Terms and Definitions
Term Definition
Average dry
weather flow
(ADWF)
Average flow rate or pattern from days without noticeable inflow or infiltration
response. ADWF usage patterns for weekdays and weekends differ and must
be computed separately. ADWF can be expressed as a numeric average or as
a curve showing the variation in flow over a day. ADWF includes the influence of
normal (non-rain event) groundwater infiltration.
Basin
Sanitary sewer collection system upstream of a given location (often a flow
meter), including all pipelines, inlets, and appurtenances. Also refers to the
ground surface area near and enclosed by the pipelines. A basin may refer to
the entire collection system upstream from a flow meter, or if flow meters are
aligned in series (flowing into each other), a basin may exclude separately
monitored basins upstream.
Depth/diameter
(d/D) ratio
Depth of water in a pipe as a fraction of the pipe’s diameter. A measure of
fullness of the pipe. This term is used as a part of Capacity Analysis.
Design storm
A theoretical storm event of a given duration and intensity that aligns with
historical frequency records of rainfall events. For example, a 10-year, 24-hour
design storm is a storm event wherein the volume of rain that falls in a 24-hour
period would historically occur once every 10 years. Design storm events are
used to predict I/I response and are useful for modeling – to approximate how a
collection system will react to a given set of storm event scenarios.
Infiltration and
Inflow
Infiltration and inflow (I/I) rates are calculated by subtracting the ADWF flow
curve from the instantaneous flow measurements taken during and after a storm
event. Flow in excess of the baseline consists of inflow, rainfall-responsive
infiltration, and rainfall-dependent infiltration. Total I/I is the total sum in gallons
of additional flow attributable to a storm event. This is calculated by subtracting
the expected ADWF totalized flow from the measured real-time totalized flow
across the limits of the storm event.
Infiltration,
Groundwater
Groundwater infiltration (GWI) is groundwater that enters the collection system
through pipe defects. GWI depends on the depth of the groundwater table
above the pipelines as well as the percentage of the system submerged. The
variation on groundwater levels and subsequent groundwater infiltration rates
are seasonal by nature. On a day-to-day basis, groundwater infiltration rates are
relatively steady and will not fluctuate greatly.
Infiltration,
Rainfall
Dependent
Rainfall Dependent Infiltration (RDI) is similar to groundwater infiltration but
occurs as a result of storm water. The storm water percolates into the soil,
submerges more of the pipe system, and enters through pipe defects. RDI is the
slowest component of storm-related infiltration and inflow, beginning gradually
and often lasting 24 hours or longer. The response time depends on the soil
permeability and saturation levels.
Infiltration,
Rainfall
Responsive
Rainfall Responsive Infiltration (RRI) is storm water which enters the collection
system through pipe defects, but normally in sewers constructed close to the
ground surface such as private laterals. RRI is independent of the groundwater
table and reaches defective sewers via the pipe trench in which the sewer is
constructed, particularly if the pipe is placed in impermeable soil and bedded and
backfilled with a granular material. In this case, the pipe trench serves as a
conduit similar to a French drain, conveying storm drainage to defective joints
and other openings in the system.
Inflow Inflow is defined as water discharged into the sewer system, including private
sewer laterals, from direct connections such as downspouts, yard and area
City of San Luis Obispo
Sanitary Sewer Flow Monitoring and Inflow/Infiltration Study

Term Definition
drains, holes in manhole covers, cross-connections from storm drains, or catch
basins. Inflow creates a peak flow problem in the sewer system and often
dictates the required capacity of downstream pipes and transport facilities to
carry these peak instantaneous flows. SSOs are often attributable to high inflow
rates.
Normalization
To run an “apples-to-apples” comparison amongst different basins, calculated
metrics must be normalized. Each basin will have different runoff areas, pipe
lengths and sanitary flows. Normalization is typically completed in three different
methods. Depending on the information available, one or all methods can be
applied to a given project:
Pipe Length: The metric is divided by the length of pipe in the upstream
basin expressed in units of inch-diameter-mile (IDM).
Basin Area: The metric is divided by the estimated drainage area of the
basin in acres.
ADWF: The metric is divided by the average dry weather sanitary flow
(ADWF).
Normalization,
Inflow
The peak I/I flow rate is used to quantify inflow. Although the instantaneous flow
monitoring data will typically show an inflow peak, the inflow response is
measured from the I/I flow rate (in excess of baseline flow). This removes the
effect of sanitary flow variations and measures only the I/I response:
Pipe Length: The peak I/I flow rate is divided by the length of pipe (IDM) in
the upstream basin. The result is expressed in gallons per day (gpd) per
IDM (gpd/IDM).
Basin Area: The peak I/I flow rate is divided by the geographic area of the
upstream basin. The result is expressed in gpd per acre.
ADWF: The peak I/I flow rate is divided by the average dry weather flow
(ADWF). This is a ratio and is expressed without units.
Normalization,
GWI
The estimated GWI rates above typical accepted GWI rates as defined by the
Water Environment Federation is used to identify basins with high GWI:
Pipe Length: The GWI flow rate is divided by the length of pipe (IDM) in the
upstream basin. The result is expressed in gallons per day (gpd) per IDM
(gpd/IDM).
Basin Area: The GWI flow rate is divided by the geographic area of the
upstream basin. The result is expressed in gpd per acre.
ADWF: The GWI flow rate is divided by the average dry weather flow
(ADWF). This is a ratio and is expressed without units.
Normalization,
RDI
The estimated RDI rates at a period 24 hours or more after the conclusion of a
storm event are used to identify basins with high RDI:
Pipe Length: The RDI flow rate is divided by the length of pipe (IDM) in the
upstream basin. The result is expressed in gallons per day (gpd) per IDM
(gpd/IDM).
Basin Area: The RDI flow rate is divided by the geographic area of the
City of San Luis Obispo

Term Definition
upstream basin. The result is expressed in gpd per acre.
ADWF: The RDI flow rate is divided by the average dry weather flow
(ADWF). This is a ratio and is expressed without units.
Normalization,
Total I/I
The estimated totalized I/I in gallons attributable to a particular storm event are
used to identify basins with high total I/I. Because this is a totalized value rather
than a rate and can be attributable solely to an individual storm event, the
volume of the storm event is also taken into consideration. This allows for a
comparison not only basin-to-basin, but also storm event-to-storm event:
Pipe Length: Total gallons of I/I are divided by the length of pipe (IDM) in
the upstream basin and the inches of rain of the storm event. The result is
expressed in gallons per IDM per inch-rain.
Basin Area (R-Value): Total gallons of I/I are divided by total gallons of
rainfall water that fell within the acreage of the basin area. This is a ratio
and expressed as a percentage. R-Value is described as “the percentage
of rain that falls that enters the collection system.” Systems with R-Values
less than 5%1 are often considered to be performing well.
ADWF: Total gallons of I/I are divided by the ADWF and the inches of rain
of the storm event. The result is expressed in gallons (x 106)per MGD of
ADWF per inch-rain.
Peaking factor
Ratio of peak measured flow to average dry weather flow. This ratio expresses
the degree of fluctuation in flow rate over the monitoring period. This is used for
Capacity Analysis.
Surcharge
When the flow level is higher than the crown of the pipe, then the pipeline is said
to be in a surcharged condition. The pipeline is surcharged when the d/D ratio
is greater than 1.0.
Synthetic
hydrograph
A set of algorithms developed to approximate the actual I/I hydrograph. The
synthetic hydrograph is developed strictly using rainfall data and response
parameters representing response time, recession coefficient and soil saturation.
Weekend/weekday
ratio
The ratio of weekend ADWFs to weekday ADWFs. In residential areas, it is
typical that this ratio would be slightly higher than 1.0. In business districts,
depending on type of service, this ratio can be significantly less than 1.0.

EXECUTIVE SUMMARY
Scope and Purpose
V&A completed sanitary sewer flow monitoring, rainfall monitoring and inflow/infiltration (I/I) analysis
within the City of San Luis Obispo, California (City). Flow and rainfall monitoring occurred over two
wet weather seasons and one dry weather season as follows:
Year 1 Wet Weather Flow Monitoring: January 29, 2010 to March 31, 2010 at 19 open
channel flow monitoring sites, seven pump stations and four rainfall monitoring sites.
Year 2 Wet Weather Flow Monitoring: January 18 to March 8, 2011 at 18 open channel
flow monitoring sites (flow locations different from Year 1).
Dry Weather Flow Monitoring: average dry weather flows were established by conducting
flow monitoring from October 20 to November 9, 2010.
The purpose of this study was to measure sanitary sewer flows at the flow monitoring sites and
conduct analyses pertaining to capacity and I/I occurring in the basins upstream from the flow
monitoring sites. Year 1 flow monitoring concentrated on the larger basins within the City to get an
aggregate idea of how the system was performing in terms of I/I. Analysis of Year 1 flow monitoring
results was applied to the Year 2 flow metering locations, placed strategically to better isolate basins
with I/I issues.
System Limitations Criterion
Per City experience, when peak hourly wet weather flows to the City's Water Reclamation Facility
(WRF) approaches or exceeds 25 million gallons per day (mgd), the City is at greater risk of a
sanitary sewer overflow within the collection system, as well as at greater risk of an overflow within
the WRF itself. The plant is allowed under the current permit to utilize an equalization basin and
“blend” peak flows. There are concerns that future permits may not allow blended flows. Inflow
directly relates to peak flows.
Rain dependent infiltration (RDI) results more typically in sustained elevated flows. Because the City
owns and operates its own treatment facility, there is less direct cost impact for treatment of sustained
RDI flows. The following important decision criterions are identified:
Reduction of inflow is identified as more critical to the City than reduction of RDI.
25 mgd at the WRF was used as the threshold value for peak wet weather flow
Estimated 10-Year, 24-Hour Storm Event Peak Flows: System
V&A conducted synthetic I/I hydrograph modeling of the collection system at the flow monitoring sites
to estimate the peak flow response for a 10-year, 24-hour storm event, with the following key results:
The peak wet weather flows to the WRF were estimated at between 31 mgd and 35 mgd.
This exceeds the 25 mgd threshold established by the City.
Conclusion: I/I reduction projects are required to identify and mitigate I/I, and specifically
inflow, within the collection system.

Collection System Inflow Results
Figure 1 summarizes the inflow results for the 19 flow monitoring basins and sub-basins that were
isolated during this study2. With the assumption that 50% inflow reduction could be achieved with a
dedicated I/I rehabilitation CIP program, the reduction in peak flows is estimated as follows:
I/I Rehabilitation, Top 9 Basins: 3.96 mgd reduction in peak flow (Basins A.2, B.1, D.1, E.2,
F.2, H.3, J.2, Q.1, R.1)
I/I Rehabilitation, Top 12 Basins: 4.97 mgd reduction in peak flow (Basins A.2, B.1, D.1, D.2,
E.2, F.2, H.2, H.3, I.2, J.2, Q.1, R.1)

Flow Monitoring Capacity Results
Peak measured flows and the flow levels (elevations) are important to understand the capacity of the
flow monitoring system. Figure 2 shows a bar graph of the d/D ratios for the flow monitoring
locations. Peak flows and flow levels are illustrated in Figure 3; results reported were from the peak
measurements as taken across the entirety of the flow monitoring period3. Capacity analysis data is
presented on a site-by-site basis and represent the hydraulic conditions only at the point site
location. Hydraulic conditions in other areas of the collection system will differ; a collection system
model would be required to properly predict capacity deficiencies within an entire collection system.
The following results are noted:
Sites H.1, M.1 and Q.1 surcharged above the pipe crown during this study, and Site A.1 was
very close to surcharging above the pipe crown.
I/I reduction efforts in the basins upstream from Sites A.1, H.1 and Q.1 may help alleviate
stress on the capacity through these sites. It is unlikely that I/I reduction efforts upstream
from Site M.1 will alleviate capacity issues.

Conclusions
The peak wet weather flows to the WRF are estimated at between 31 mgd and 35 mgd for a
10-year, 24-hour storm event. This exceeds the 25 mgd threshold established by the City.
To reduce peak wet weather flows to acceptable levels for a 10-year, 24-hour storm event,
the City needs to reduce peak flows by 6 to 10 mgd.
Reduction of peak flows are achieved by a focused I/I reduction CIP program; this program
should be focused on reduction of the inflow component of I/I.
Assuming 50% reduction in peak I/I flows with a focused I/I reduction program, peak flows
are estimated to be reduced by the following flow rates:
♦ I/I Rehabilitation to Basins A.2, B.1, D.1, E.2, F.2, H.3, J.2, Q.1, R.1 (Top 9 Inflow
Basins): approximately 4 mgd reduction in peak flow
♦ I/I Rehabilitation to Basins A.2, B.1, D.1, D.2, E.2, F.2, H.2, H.3, I.2, J.2, Q.1, R.1 (Top 12
Inflow Basins): approximately 5 mgd reduction in peak flow
♦ Note: the entire City collection system was not evaluated as a part of this study.
Additional effective inflow reduction may be possible in the unmonitored areas of the
collection system, including the downtown areas of the City.
Recommendations
Preface: Typical recommendations for identifying and locating sources of inflow would include smoke
testing and possible CCTV work. However, it is understood that the City has undertaken smoke
testing and CCTV efforts in the past with minimal success, and that the City is interested in exploring
other options of I/I Reduction. The programs recommended as follows are listed in this regard:
Lower Lateral Replacement Program: The City should budget and plan for a lower lateral
replacement program for the highest inflow basins, including the following items:
♦ Pilot Project(s): Pilot studies should be conducted for the initial rehabilitation work to
evaluate the effectiveness of lower lateral replacement and rehabilitation. Pilot
replacement projects should be scheduled in smaller neighborhoods that can be
effectively isolated for accurate flow monitoring (next bullet).
♦ I/I Effectiveness Study: Before and after construction flow monitoring should be
performed to determine the effectiveness of the I/I rehabilitation and replacement
projects. A sample I/I Effectiveness Study is shown in Appendix E.
♦ Alternatives: The City can plan for both lower and upper lateral replacement CIP
projects, including pilot projects with I/I effectiveness studies. This would be more
effective and more definitive in reducing inflow, but likely more difficult due to lateral
ownership issues.
Sewer Lateral Grant Program: the City should institute a sewer lateral grant program to
encourage residents to replace upper laterals. This program involves partial subsidization of
lateral replacement. The property owner would apply for a grant from the City to partially pay
for the lateral replacement. To be approved for this program, the lateral would have to be
replaced according to standards and specifications set by the District. This program has been
City of San Luis Obispo
Sanitary Sewer Flow Monitoring and Inflow/Infiltration Study
09-0578 SLO 2010-2011 FM and II Final Report.docx Page 6 of 44
utilized within several municipalities with success. Several sample Lateral Grant Programs
are shown in Appendix C.
Sewer Lateral Testing Ordinances: the City should pass a City ordinance requiring the
testing of sewer laterals upon property sale or upon property construction upgrade requiring a
re-evaluation of the property. Private laterals would have to pass a pressure test prior to the
final sale of a property. The costs of lateral replacement can be planned for in escrow. This
program is similar to requiring a termite inspection. Several sample Lateral Testing
Ordinances are shown in Appendix D.
In the event that inflow sources not related to sewer laterals are located via other means, or by
reconsidered CCTV or smoke testing work, the following recommendations are made:
Storm Drain Connections: Perform closed-circuit television (CCTV) and/or dye tracing to
determine the mode and path of the identified storm drain cross-connections. Upon
confirmation of cross-connection of the storm sewer system to the sanitary sewer system,
consider removing the cross-connection and repairing the affected pipelines.
Area Drain Connections: Perform closed-circuit television (CCTV) and/or dye tracing to

INTRODUCTION
Scope and Purpose
V&A has completed sanitary sewer flow monitoring, rainfall monitoring and inflow/infiltration (I/I)
analysis within the City of San Luis Obispo, California (City). Flow and rainfall monitoring occurred
over two wet weather seasons and one dry weather season as follows:
Year 1 Wet Weather Flow Monitoring: January 29, 2010 to March 31, 2010 at 19 open
channel flow monitoring sites, seven pump stations and four rainfall monitoring sites.
Year 2 Wet Weather Flow Monitoring: January 18 to March 8, 2011 at 18 open channel
flow monitoring sites (flow locations different than Year 1).
Dry Weather Flow Monitoring: average dry weather flows were established by conducting
flow monitoring from October 20 to November 9, 2010.
The purpose of this study was to measure sanitary sewer flows at the flow monitoring sites and
conduct analyses pertaining to capacity and infiltration and inflow (I/I) occurring in the basins
upstream from the flow monitoring sites. Year 1 flow monitoring concentrated on the larger basins
within the City to get an aggregate idea of how the system was performing in terms of I/I. Analysis of
Year 1 flow monitoring results was applied to the Year 2 flow metering locations, to be placed
strategically to better isolate basins with I/I issues.
Relocation of flow meters results in different data and different storm events for the newly defined
basins and sub-basins. An “apples-to-apples” comparison of basins to each other is made by
applying synthetic I/I hydrograph methodology (this section of the report starts on Page 32). The
general strategy for capturing as much relevant data as possible and applying I/I analysis techniques
to best isolate and optimize I/I analysis within the entirely of the collection system is shown as follows:
1. Season 1
a. The City selects basins for flow monitoring with 19 flow meters. Additionally, pump station
monitoring was conducted at seven pump stations.
b. V&A conducts preliminary analysis of the flow monitoring and I/I data. I/I analysis utilized
baseline flows established from Season 1 data. (Note: Dry weather flow data would be
obtained during dry weather flow monitoring to be conducted later in the year. Refined I/I
analysis would be conducted as a part of the Season 2 study utilizing the dry weather
flow data.)
c. Basins with higher infiltration and inflow rates were considered for either additional flow
monitoring and sub-basin isolations. Basins with lower I/I rates may not be considered
for sub-basin monitoring.
2. Dry Weather Monitoring: Dry weather monitoring to take place to establish baseline flow
rates though Season 1 (past) and Season 2 (future) flow monitoring sites.
3. Season 2
a. The City selects additional basins for flow monitoring with 18 flow meters.

b. I/I analysis is conducted on Season 2 flow monitoring results.
4. Final Analysis
a. Synthetic hydrograph analysis methods are used for normalization of Season 1 and
Season 2 flows amongst the different basins and sub-basins.
b. A 10-year, 24-hour design storm event is used for final estimation of basin and sub-basin
response and basin and sub-basin normalization of flows.
c. Both Year 1 and Year 2 flow monitoring results are summarized in a final report.
System and Plant Limitations
Per City experience, when peak wet weather flows to the City's Water Reclamation Facility (WRF)
approaches or exceeds 25 mgd, the City is at greater risk of a sanitary sewer overflow within the
collection system, as well as at greater risk of an overflow within the WRF itself. These excessive
flows also put the City at greater risk of a permit violation (specifically, turbidity levels). The WRF
relies on the ability to “blend” flows during periods of excessive flow. There is concern that “blended”
flows will not be allowed under future permits. For the purposes of this study, 25 mgd at the WRF will
be used as the threshold value for peak wet weather flow.
Flow Monitoring Sites and Basins
Flow Monitoring Sites: Flow monitoring sites are the locations where the flow monitors were placed.
Flow monitoring site data may include the flows of one or many drainage basins. To isolate a flow
monitoring basin, an addition or subtraction of monitored flows may be required4. Capacity and flow
rate information is presented on a site-by-site basis.
Flow Monitoring Basins: Flow monitoring basins are localized areas of a sanitary sewer collection
system upstream of a given location (often a flow meter), including all pipelines, inlets, and
appurtenances. The basin refers to the ground surface area near and enclosed by the pipelines5. A
basin may refer to the entire collection system upstream from a flow meter, or if flow meters are
aligned in series (flowing into each other), a basin may exclude separately monitored basins
upstream. I/I analysis in this report will be conducted on a basin-by-basin basis.
The flow monitoring sites and rain gauge sites are listed in Table 1 and illustrated in Figure 4. The
flow monitoring basins are described in Table 2 and illustrated in Figure 5. Detailed descriptions of
the individual flow monitoring sites, including photographs, are included in Appendix B.
4 There is error inherent in flow monitoring. Adding and subtracting flows increases error on an additive basis. For example, if
Site A has error ±10% and Site B has error ±10%, then the resulting flow when subtracting Site A from Site B would be ±20%. 5 Data for the basin areas (in acres) were estimated by V&A based on sewer maps provided by the City.

Rain Gauges
V&A captured rainfall data from nine different rain gauges scattered across the City. San Luis Obispo
has varying topography and the volume and intensity of rainfall can vary across terrain. Figure 6
shows the rain gauge locations utilized for this study.

METHODS AND PROCEDURES
Confined Space Entry
A confined space (Photo 1) is defined as any space that is large enough and so configured that a
person can bodily enter and perform assigned work, has limited or restricted means for entry or exit
and is not designed for continuous employee occupancy. In general, the atmosphere must be
constantly monitored for sufficient levels of oxygen (19.5 to 23.0%), and the absence of hydrogen
sulfide (H2S) gas, carbon monoxide (CO) gas and lower explosive limit (LEL) levels. A typical
confined space entry crew has members with OSHA-defined responsibilities of: Entrant, Attendant
and Supervisor. The Entrant is the individual performing the work. He or she is equipped with the
necessary personal protective equipment needed to perform the job safely, including a personal four-
gas monitor (Photo 2). If it is not possible to maintain line-of-sight with the Entrant, then more
Entrants are required until line-of-sight can be maintained. The Attendant is responsible for
maintaining contact with the Entrant(s) to monitor the atmosphere on another four-gas monitor and
maintaining records of all Entrants, if there are more than one. The Supervisor develops the safe
work plan for the job at hand prior to entering.

Flow Meter Installation
Two different types of flow meters were used on this project. The mounting and installation
techniques utilized are described below.
Isco 2150 meters use submerged sensors with a pressure transducer to collect depth readings and
an ultrasonic Doppler sensor to determine the average fluid velocity. The ultrasonic sensor emits
high-frequency (500 kHz) sound waves, which are reflected by air bubbles and suspended particles in
the flow. The sensor receives the reflected signal and determines the Doppler frequency shift, which
indicates the estimated average flow velocity. The sensor is typically mounted at a manhole inlet to
take advantage of smoother upstream flow conditions. The sensor may be offset to one side to lessen
the chances of fouling and sedimentation where these problems are expected to occur. Figure 7
shows a typical flow meter installation.
A Flo-Dar flow meter is a non-contact flow meter that uses radar to measure velocity and a down-
looking ultrasonic sensor to measure depth. Figure 8 shows a sketch of a typical Flo-Dar installation.

Manual level and velocity measurements were taken during installation of the flow meters and again
when they were removed. These manual measurements were compared to simultaneous level and
velocity readings from the flow meters to ensure proper calibration and accuracy. The pipe diameter
was also verified in order to use the correct geometry in calculating flows. The continuous depth and
velocity readings were recorded by the flow meters on a 5-minute interval.
Flow Calculation
Data retrieved from the flow meters was placed into a spreadsheet program for analysis. Data
analysis includes data comparison to field calibration measurements, as well as necessary geometric
adjustments as required for sediment (sediment reduces the pipe’s wetted cross-sectional area
available to carry flow). Based on site hydraulic conditions, data was analyzed for velocity outliers
and level drift. In cases of velocity sensor failure due to fouling, gaps were filled using the correlation
between level and velocity in the remaining data. The adjustments made were based on best
engineering practices in reducing systematic error in the measurements. Area-velocity flow metering
uses the continuity equation,
AVQ⋅=,
where Q is the volume flow rate, V is the average velocity as determined by the ultrasonic sensor,
and A is the cross-sectional area of flow as determined from the depth of flow.
In a circular pipe, the following formula is used to calculate the cross-sectional area:

Rainfall: Rain Gauge Triangulation
Method
The rainfall affecting the sanitary sewer collection system basins must be calculated based on the
proximity to the rain gauge locations. The mean precipitation for each site was calculated by taking
data from three local rain gauges and using the inverse distance weighting (IDW) method. IDW is an
interpolation method that assumes the influence of each rain gauge location diminishes with distance.
The approximate geographic coordinates of each site were determined and a weighted average was
taken of the precipitation data from nearby rain gauge locations. In the IDW function,
∑=
p
p
d
dw1

the weight w depends on the distance d and a user-defined power p (p > 0).
The most common choice for hydrological studies of watershed areas is p = 2. Figure 9 illustrates the
IDW method with sample data. The IDW method was applied to the sewerage basins for San Luis
Obispo and the weighting distribution per rain gauge per basin is shown in Table 4.

weather flows. Average dry weather flows were established during the dry season flow monitoring
that took place from October 20 to November 9, 2010. Table 5 lists the average dry weather flow
(ADWF) recorded during this study for the flow monitoring sites. Figure 10 shows a schematic
diagram of the average dry weather flows and flow levels. Detailed graphs of the flow monitoring
data on a site-by-site basis are included in Appendix B.

Flow Monitoring: Peak Measured Flows and Pipeline Capacity Analysis
Peak measured flows and the flow level (elevation) at the peak flow is important to understand the
capacity of the flow monitoring system. The peak flows and flow levels reported are from the peak
measurements as taken across the entirety of the flow monitoring period. These may or may not
correspond to a rainfall event. It did not appear that there were any elevated flow levels due to
blockages, grease or roots during the flow monitoring study.
The following capacity analysis terms are defined as follows:
Peaking Factor: Peaking factor is defined as the peak measured flow divided by the average
dry weather flow (ADWF). A peaking factor threshold value of 3.0 is commonly used for
sanitary sewer design.
d/D Ratio: The d/D ratio is the peak measured depth of flow divided by the pipe diameter. A
d/D ratio less than 0.75 is a common threshold value used for pipe design. The d/D ratio for
each site was computed based on the maximum depth of flow for the flow monitoring study.
Table 6 summarizes the peak recorded flows, levels, d/D ratios and peaking factors per site during
the flow monitoring period. The following items are noted:
Capacity analysis data is presented on a site-by-site basis and represents the hydraulic
conditions only at the point site location. Hydraulic conditions in other areas of the collection
system will differ.
Due to different flow data capture periods, the peak flows and peak levels should not
necessarily be directly compared to each other.

Inflow / Infiltration Analysis: Definitions and Identification
Inflow / Infiltration (I/I) consists of storm water and groundwater which enters the sewer system
through pipe defects and improper storm drainage connections, defined as follows:
Inflow Definition
Definition: Storm water inflow is defined as water discharged into the sewer system,
including private sewer laterals, from direct connections such as downspouts, yard and area
drains, holes in manhole covers, cross connections from storm drains, or catch basins.
Impact: This component of I/I creates a peak flow problem in the sewer system and often
dictates the required capacity of downstream pipes and transport facilities to carry these peak
instantaneous flows. Because the response and magnitude of inflow is tied closely to the
intensity of the storm event, the short-term peak instantaneous flows may result in
surcharging and overflows within a collection system. Severe inflow may result in sewage
dilution, resulting in upsetting the biological treatment (secondary treatment) at the treatment
facility.
Cost of Source Identification and Removal: Inflow locations are usually less difficult to find
and less expensive to correct. These sources include direct and indirect cross connections
with storm drainage systems, roof downspouts, and various types of surface drains.
Generally, the costs to identify and remove sources of inflow are low compared to potential
benefits to public health and safety, or the costs of building new facilities to convey and treat
the resulting peak flows.
Graphical Identification: Inflow is usually recognized graphically by large magnitude, short
duration spikes immediately following a rain event.
Infiltration Definition
Definition: Infiltration is defined as water entering the sanitary sewer system through
defective pipes, pipe joints, and manhole walls, and may include cracks, offset joints, root
intrusion points, and broken pipes.
Impact: Infiltration typically creates long-term annual volumetric problems. The major impact
is the cost of pumping and treating the additional volume of water, and of paying for treatment
(for municipalities that are billed strictly on flow volume).
Cost of Source Detection and Removal: Infiltration sources are usually harder to find and
more expensive to correct than inflow sources. Infiltration sources include defects in
deteriorated sewer pipes and/or manholes, and may include cracks, offset joints, root
intrusion points, and broken pipes. The sources may be wide-spread throughout a sanitary
sewer system.
Graphical Identification: Infiltration is often recognized graphically by a gradual increase in
flow after a wet weather event. The increased flow typically sustains for a period after rainfall
has stopped and then gradually drops off as soils become less saturated, and as
groundwater levels recede to normal levels.
Figure 14 shows sample graphs indicating the typical graphical response patterns for inflow/
infiltration.

Figure 14. Inflow / Infiltration Graphical Response Patterns
Infiltration Components
Infiltration can be further subdivided into components as follows:
Groundwater Infiltration – Groundwater infiltration depends on the depth of the
groundwater table above the pipelines as well as the percentage of the system submerged.
The variation on groundwater levels and subsequent groundwater infiltration rates are
seasonal by nature. On a day-to-day basis, groundwater infiltration rates are relatively
steady and will not fluctuate greatly.
Rainfall Dependent Infiltration – This component occurs as a result of storm water and
enters the sewer system through pipe defects similar to groundwater infiltration. The storm
water first percolates directly into the soil and then migrates to an infiltration point. Typically,
the time of concentration for rainfall related infiltration may be 24 hours or longer, but
depends on the soil permeability and saturation levels.
Rainfall Responsive Infiltration is storm water which enters the collection system indirectly
through pipe defects, but normally in sewers constructed close to the ground surface such as
private laterals. Rainfall responsive infiltration is independent of the groundwater table, and
reaches defective sewers via the pipe trench in which the sewer is constructed, particularly if
the pipe is placed in impermeable soil and bedded and backfilled with a granular material. In
this case, the pipe trench serves as a conduit similar to a French drain, conveying storm
drainage to defective joints and other openings in the system. Note: this type of infiltration
can have a quick response and graphically can look very similar to inflow.

Inflow / Infiltration: Analysis Methods
After differentiating I/I flows from ADWF flows, various calculations can be made to determine which
I/I component (inflow or infiltration) is more prevalent at a particular site, and to compare the relative
magnitude of the I/I components between drainage basins and between storm events.
Inflow Indicators
Peak I/I Flow Rate: Inflow is characterized by sharp, direct spikes occurring during a rainfall event.
Peak I/I rates are isolated for inflow analysis7. After determining the peak I/I flow rate for a given site,
and for a given storm event, there are three ways to normalize the peak I/I rates for an “apples-to-
apples” comparison amongst the different drainage basins:
Peak I/I Flow Rate per IDM: Peak measured I/I rate divided by length of pipe within the
drainage basin, expressed in units of inch-diameter-mile (IDM) (miles of pipeline multiplied by
the diameter of the pipeline in inches). Final units are gallons per day (gpd) per IDM.
Peak I/I Flow Rate per Acre: Peak measured I/I rate divided by the basin size of the
drainage basin, basin units expressed in acres. Units are gpd per acre.
Peak I/I Flow Rate to ADWF Ratio: Peak measured I/I rate divided by average dry weather
flow (ADWF). This is a ratio and is expressed without units.
The inflow indicators were normalized by all methods in this report; rankings were determined by the
per-IDM method.
Infiltration Indicators
Dry Weather Groundwater Infiltration: GWI analysis is conducted by looking at minimum dry
weather flow to average dry weather flow ratios and comparing them to established standards, which
may result in quantifying the rate of excess ground water infiltration. Similar to the discussion on
inflow, GWI infiltration rates can be normalized by means of pipe length (IDM), basin area (acres)
and/or dry weather flow rates (ADWF). These methods are discussed in further detail in the
Groundwater Analysis section later in this report.
Rainfall Dependent Infiltration: Infiltration occurring after the conclusion of a storm event is
classified as rainfall dependent infiltration. Analysis is conducted by looking at the infiltration rates at
set periods after the conclusion of a storm event. Depending on the system and the time required for
flows to return to ADWF levels, different set periods may be examined to determine the basins with
the greatest or most sustained rainfall dependent infiltration rates.
The infiltration indicators were normalized by all methods in this report; rankings were determined by
the per-IDM method.
7 I/I flow rate is the realtime flow less the estimated average dry weather flow rate. It is an estimate of only flows attributable to
rainfall. By using peak flow rates (inclusive of ADWF) The I/I flow rate can be skewed higher or lower depending on whether
the storm event I/I response occurs during low flow or high flow hours.

Combined I/I Indicators
Total Infiltration: The total inflow and infiltration is measured in gallons per site and per storm event.
Because it is based on total I/I volume, it is an indicator of combined inflow/infiltration and is used to
identify the overall volumetric influence of I/I within the monitoring basin. As with inflow, pipe length,
basin area and dry weather flow are used to normalize combined I/I for basin comparison:
Combined I/I Flow Rate per IDM: Total infiltration (gallons) divided by length of pipe (IDM)
and divided by storm event rainfall (inches of rain). Final units are gallons per day (gpd) per
IDM per inch-rain.
R-Value: Total infiltration (gallons) divided by the total rainfall that fell within the acreage of
that basin (gallons of rainfall). This is expressed as a percentage and is explained as “the
percent of rain that falls that enters the sanitary sewer collection system.” Systems with R-
Values less than 5%8 are often considered to be performing well.
Combined I/I Flow Rate per ADWF: Total infiltration (gallons) divided by the ADWF (gpd)
and divided by storm event rainfall (inches of rain). Final units are gallons (x 106) per MGD of
ADWF per inch-rain.
The combined I/I flow indicators were normalized by all methods in this report; rankings were
determined by the per-IDM method.
Realtime flows were plotted against ADWF flows to analyze the I/I response to rainfall events. Figure
16 illustrates a sample of how this analysis is conducted and some of the measurements that are
used to distinguish infiltration and inflow. Similar graphs were generated for the flow monitoring sites
and can be found in Appendix B.

Inflow / Infiltration: Analysis Plan and Strategy
There were different flow metering sites for the Year 1 and Year 2 data sets. Year 1 flow monitoring
concentrated on the larger basins within the City to get an aggregate idea of how the system was
performing in terms of I/I. Analysis of Year 1 flow monitoring results was applied to the Year 2 flow
metering locations, to be placed strategically to better isolate basins with I/I issues.
Relocation of flow meters results in different data and different storm events for the newly defined
basins and sub-basins. An “apples-to-apples” comparison of basins to each other is made by
applying synthetic I/I hydrograph methodology (next section). The general strategy for capturing as
much relevant data as possible and applying I/I analysis techniques to best isolate and optimize I/I
analysis within the entirely of the collection system is shown as follows:
1. Season 1
a. The City selects basins for flow monitoring with 19 flow meters. Additionally, pump station
monitoring was conducted at seven pump stations.
b. V&A conducts preliminary analysis of the flow monitoring and I/I data. I/I analysis utilized
baseline flows established from Season 1 data. (Note: Dry weather flow data would be
obtained during dry weather flow monitoring to be conducted later in the year. Refined I/I
analysis would be conducted as a part of the Season 2 study utilizing the dry weather
flow data.)
c. Basins with higher infiltration and inflow rates were considered for additional flow
monitoring and sub-basin isolations. Basins with lower I/I rates may not be considered
for sub-basin monitoring.
2. Dry Weather Monitoring: Dry weather monitoring to take place to establish baseline flow
rates though Season 1 (past) and Season 2 (future) flow monitoring sites.
3. Season 2
a. The City selects additional basins for flow monitoring with 18 flow meters.
b. I/I analysis is conducted on Season 2 flow monitoring results.
4. Final Analysis
a. Synthetic hydrograph analysis methods are used for normalization of Season 1 and
Season 2 flows amongst the different basins and sub-basins.
b. A 10-year, 24-hour design storm event is used for final estimation of basin and sub-basin
response and basin and sub-basin normalization of flows.
c. Both Year 1 and Year 2 flow monitoring results are summarized in a final report.

Inflow / Infiltration: Synthetic Hydrographs
In order to model design storms, synthetic hydrographs were developed to approximate the actual
RDI/I hydrograph shape in terms of parameters representing time to the peak and the recession
coefficient. The actual RDI/I hydrograph was best matched with a synthetic hydrograph by separating
the synthetic hydrograph into seven volume components (R1, R2, R3, R4, R5, R6, R7). The seven
components represent different response times to the rainfall event and, therefore, different infiltration
or inflow paths into the sewer system. R1 is characterized by a short response time and is assumed
to consist of mainly inflow. R7 represents slower response and longer recession times and consists of
mostly infiltration. Levels of soil saturation are also considered. Using synthetic hydrograph analysis,
appropriate time and recession parameters were estimated by a iterative procedure until a good
match was obtained. For example, the hydrograph and its component hydrographs for the period of
February 1 to March 2, 2010 for Site D.1 is shown in Figure 17.

Design Storm Development
With the I/I response modeled by a synthetic hydrograph, design storms can be applied. This serves
two functions: (a) predicted flows are based on one like storm event and are hence normalized to
each other, making for easier and better comparisons, and (b) the resulting I/I flows can be predicted
for a design storm event. This helps to calibrate modeling efforts that will determine if the collection
system has adequate capacity to handle very large storm events.
V&A used a 10-year, 24-hour design storm for this analysis. Storm events were taken from the
NOAA Precipitation-Frequency Atlas of the Western United States. Figure 18 summarizes the design
storm magnitude and profile. This particular profile distribution also fits the NOAA criterion for 2-hour

Design Storm Response Summary
The 10-year, 24-hour storm event was applied to the synthetic I/I hydrograph components developed
specific to each flow monitoring site. This method effectively models and extrapolates the best
estimated response to the design storm events. These results assume full ground saturation, and the
peak I/I flows from the design storm coincide with peak dry weather flows to get a “worst-case”
scenario of peak wet weather flows. Figure 19 shows the synthetic hydrograph response for the
design storm event at Site D.2. Table 7 summarizes the final results for each design storm on a site-
by-site basis.

9 Total I/I was measured through Day 12 for this study (only through Day 5 shown on above graph).
10 For this analysis, the RDI rate was is the average rate of I/I during Day 4 of the design storm. This is over 24 hours after the
conclusion of rainfall and all I/I can be considered rain dependent infiltration with no influence from inflow. The RDI rates
shown in the above table is not a component of the peak I/I or peak flow rates.

Notes: A decent percentage of the collection system, including basins within the downtown area, was
not monitored as a part of this study. Using a system average dry weather flow of 4.6 mgd, the
extrapolated peak flow at the treatment facility for a 10-year, 24-hour design storm event would
measure between 31 and 35 mgd.

Attenuation
Flow attenuation in a sewer collection system is the natural process of the reduction of the peak flow
rate through redistribution of the same volume of flow over a longer period of time. This functions as
a result of friction (resistance), internal storage and diffusion along the sewer pipes. Fluids are
constantly working towards equilibrium. For example, a volume of fluid poured into a static vessel
with no outside turbulence will eventually stabilize to a static state, with a smooth fluid surface without
peaks and valleys. Attenuation within a sanitary sewer collection system is based upon this concept.
A flow profile with a strong peak will tend to stabilize towards equilibrium, shown in Figure 20.
TimeFlow TimeFlowTime
Vol. X Volume Y
Volume X = Volume Y
Figure 20. Attenuation Illustration
Within a sanitary sewer collection system, each individual basin will have a specific flow profile. As
the flows from the basins combine within the trunk sewer lines, the peaks from each basin will (a) not
necessary coincide at the same time, and (b) due to the length and time of travel through the trunk
sewers, peak flows will attenuate prior to reaching the treatment facility. The sum of the peak flows of
the individual basins within a collection system will be greater than the peak flows observed at the
treatment facility. For this project, an attenuation factor11 of 0.85 was applied to upstream basins.
11 The attenuation factor of 0.85 is an estimated system-wide number used and applied based on V&A’s experience in flow
monitoring and observation of peak flow reduction. Actual attenuation will differ on a site-by-site basis and would need to be
measured individually between basins using advanced flow monitoring techniques beyond the scope of this study.

Inflow Results Summary
Table 8 summarizes the peak measured I/I flows and inflow analysis results for the design storm
event (refer to the I/I Methods section for more information on inflow analysis methods). Inflow rates
were normalized by the “per-ADWF” and the “per-ACRE” methods. Temperature maps of both
methods are shown in Appendix A. A temperature map by overall ranking is shown in Figure 21.

CONCLUSIONS
The peak wet weather flows to the WRF are estimated at between 31 mgd and 35 mgd for a
10-year, 24-hour storm event. This exceeds the 25 mgd threshold established by the City.
To reduce peak wet weather flows to acceptable levels for a 10-year, 24-hour storm event,
the City needs to reduce peak flows by 6 to 10 mgd.
Reduction of peak flows are achieved by a focused I/I reduction CIP program; this program
should be focused on reduction the inflow component of I/I.
Assuming 50% reduction in peak I/I flows with a focused I/I reduction program, peak flows
are estimated to be reduced by the following flow rates:
♦ I/I Rehabilitation to Basins A.2, B.1, D.1, E.2, F.2, H.3, J.2, Q.1, R.1 (Top 9 Inflow
Basins): approximately 4 mgd reduction in peak flow
♦ I/I Rehabilitation to Basins A.2, B.1, D.1, D.2, E.2, F.2, H.2, H.3, I.2, J.2, Q.1, R.1 (Top 12

♦ Note: the entire City collection system was not evaluated as a part of this study.
Additional effective inflow reduction may be possible in the unmonitored areas of the
collection system, including the downtown areas of the City.
RECOMMENDATIONS
Preface: Typical recommendations for identifying and locating sources of inflow would include smoke
testing and possible CCTV work. However, it is understood that the City has undertaken smoke
testing and CCTV efforts in the past with minimal success, and that the City is interested in exploring
other options of I/I Reduction. The programs recommended as follows are listed in this regard:
Lower Lateral Replacement Program: The City should budget and plan for a lower lateral
replacement program for the highest inflow basins, including the following items:
♦ Pilot Project(s): Pilot studies should be conducted for the initial rehabilitation work to
evaluate the effectiveness of lower lateral replacement and rehabilitation. Pilot
replacement projects should be scheduled in smaller neighborhoods that can be
effectively isolated for accurate flow monitoring (next bullet).
♦ I/I Effectiveness Study: Before and after construction flow monitoring should be
performed to determine the effectiveness of the I/I rehabilitation and replacement
projects. A sample I/I Effectiveness Study is shown in Appendix E.
♦ Alternatives: The City to plan for both lower and upper lateral replacement CIP projects,
including pilot projects with I/I effectiveness studies. This would be more effective and
more definitive in reducing inflow, but likely more difficult due to lateral ownership issues.
Sewer Lateral Grant Program: the City should institute a sewer lateral grant program to
encourage residents to replace upper laterals. This program involves partial subsidization of
lateral replacement. The property owner would apply for a grant from the City to partially pay
for the lateral replacement. To be approved for this program, the lateral would have to be
replaced according to standards and specifications set by the District. This program has been
utilized within several municipalities with success. Several sample Lateral Grant Programs
are shown in Appendix C.

Sewer Lateral Testing Ordinances: the City should pass a City ordinance requiring the
testing of sewer laterals upon property sale or upon property construction upgrade requiring a
re-evaluation of the property. Private laterals would have to pass a pressure test prior to the
final sale of a property. The costs of lateral replacement can be planned for in escrow. This
program is similar to requiring a termite inspection. Several sample Lateral Testing
Ordinances are shown in Appendix D.
In the event that inflow sources not related to sewer laterals are located via other means, or by
reconsidered CCTV or smoke testing work, the following recommendations are made:
Storm Drain Connections: Perform closed-circuit television (CCTV) and/or dye tracing to
determine the mode and path of the identified storm drain cross-connections. Upon
confirmation of cross-connection of the storm sewer system to the sanitary sewer system,
consider removing the cross-connection and repairing the affected pipelines.
Area Drain Connections: Perform closed-circuit television (CCTV) and/or dye tracing to
determine the mode and path of the area drain cross-connections. Work with the property
owner to confirm the illicit connection. Upon confirmation of a connection, coordinate with the
property owner to remove the connection.
Roof Leader Connections: Work with the property owner to confirm the illicit connection.
Upon confirmation of a connection, coordinate with the property owner to remove the
connection.
Faulty Cleanouts: Consider ways to ensure that homeowners maintain cleanouts on their
property. At a minimum, missing or broken cleanout caps should be replaced.

WHAT iS A SEWER LATERAL?
Within the Castro Valley Sanitary District (CVSan), the
building lateral is defined as the portion of the sewer
system, beginning at the junction with the building
plumbing system, usually located within two (2) feet of
the foundation wall of the building, and extending to
and including the connection to the public sewer main
(see Figure #1, at right). The building lateral is the pri-
vate property of the property owner who is, therefore,
responsible for all costs relating to the installation, con-
nection, maintenance, repair, construction, alteration,
abandonment or removal of the building lateral.
These building laterals are often a significant source of
infiltration and inflow (“I/I”). The Lateral Replacement
Grant Program (LRGP), is designed to help defray a
portion of the costs when the property owner or their
agent is required to replace the entire lateral including
the connection to the main.
AMOuNT OF gRANT
The maximum amount of assistance for any one resi-
dential building lateral replacement or repair is 50% of
the approved cost up to a maximum reimbursement of
$2,000. Only complete replacement of the building
lateral or repair in excess of $2,000, that completely
eliminates infiltration and inflow is eligible for the
program. Not all applications will be granted. All ap-
plications are subject to a Condition Rating by CVSan.
The property owner is responsible for notifying their
selected contractor that their entire building lateral
must pass CVSan inspection requirements (even if only
a partial replacement was performed) in order to be eli-
gible for reimbursement. Grant payment shall be made
to the property owner(s).
Notice: All work for the LRGP must be performed by
a licensed contractor qualified by CVSan. For a list of
CVSan qualified contractors, please visit www.cvsan.org
or contact CVSan at 510-606-1300.
BEFORE BEgiNNiNg ANY CONSTRuCTiON WORK:
A. A video inspection must be performed by a contractor, and
witnessed by CVSan personnel.
B. Property owner must submit a completed application, including
price quotes from at least three (3) CVSan Qualified Contractors.
C. A Letter of Approval must be issued by CVSan to property owner.
iMPORTANT
REquiREMENTS
Warning: If the above requirements are not met prior to commencement of construction work, no funds will be
obligated to the property owner.
LR g P
CHECKLiST
LATERAL iNSPECTiNg
Lateral inspection must be performed prior to repair or
replacement of the building lateral in order for grant
funding to be considered. Inspecting and testing
methods shall include the following technique:

What is a Condition Rating?
Condition rating is an assessment of the sewer lateral to
determine the degree of defects to the line. Condition ratings
take into consideration: pipe cracks, roots, water infiltration
evidence, and other defects. Each defect is given a numerical
designation (this is similar to the method used on public sanitary
sewer lines). Those laterals in poor condition (condition rating)
will receive grant funding.

Lateral Grant Application
Guidelines
ENGINEERING DEPARTMENT
450 Civic Center Plaza
Richmond, California 94804
Introduction
In 2006, the City of Richmond adopted an ordinance requiring all private sewer mains and laterals to be
certified as meeting the standards set forth in Richmond Municipal Code Chapter 12.17. To obtain the
required “Certificate of Lateral Compliance,” many property owners must incur significant costs to repair
or replace private mains or laterals. To help defray the costs to property owners, the City has budgeted
$100,000 per fiscal year for ten years to be distributed as grants of up to $3,000 each to qualifying
applicants. Residents who own their homes and tax-exempt public service organizations owning property
within the Richmond Sanitary Sewer District may apply for a grant of up to $3,000 as reimbursement for
costs incurred to bring a private sewer main or lateral into compliance.
Eligibility Guidelines:
1. Eligible applicants own property served by the Richmond Sanitary Sewer District and they are
either (i) the occupying owner(s) of a residence, or (ii) a tax-exempt public service organization.
Owners of property within the City of Richmond served by the Stege Sanitary District or West
County Wastewater District are not eligible to receive City grants. Tax-exempt organizations must
attach proof of tax-exempt status to the grant application. Before awarding any grants, the City
will verify property ownership.
2. Prior to applying for a grant, the eligible applicant must have the private sewer main or lateral
inspected in accordance with Richmond Municipal Code Section 12.17.050. If the inspection
reveals that the private main or lateral requires repairs or replacement in order to meet the City’s
standards (set forth at RMC Chapter 12.17), then the property owner must seek competitive bids
from a minimum of three contractors duly licensed in California to perform the necessary work in
order to be eligible for a grant. Copies of at least three bids must be attached to the grant
application, unless the applicant received a Certificate of Lateral Compliance prior to May 16,
2008. If the applicant holds a valid Certificate of Lateral Compliance issued prior to May 16, 2008,
she or he must attach to the grant application a receipt from a duly licensed contractor for work
performed on the subject private main or lateral in order to bring it into compliance. Only the
property owner who paid for the work will be eligible for a grant; a person who acquired the
property after the Certificate of Lateral Compliance was issued will not be eligible for a grant.
Eligible property owners who received Certificates of Compliance prior to May 16, 2008 may
submit grant applications for a period of two years from the date of the Certificate of Lateral
Compliance.
3. Complete grant applications must be received by 5 pm on the published deadline. Each fiscal
year, the City will accept grant applications by mail or in person on the date and at the place
published in the Notice of Grant Availability. The Notice of Grant Availability will be minimally
posted on the City’s website, at the Engineering counter, and at the Building Services counter, and
it will be published in the West County Times. The City reserves the right to reject all incomplete
applications. Grant recipients will be notified by mail or, if an e-mail address is provided, by e-mail
within sixty days from receipt of the application.
2009-09-21 Page 2 of 2
4. Funds will be disbursed to grant recipients after they have received Certificates of Compliance.
Every grant recipient must complete the work necessary to bring the private sewer main or lateral
into compliance with Richmond Municipal Code Chapter 12.17 and receive a Certificate of
Compliance before the City will issue a check for the grant funds.
Award Limits:
1. Grants will not exceed one half of the lowest competitive bid for the required work, or, in the
case of applicants holding a Certificate of Lateral Compliance issued prior to May 1, 2008, one
half of actual costs incurred for the required work, up to a maximum award of $3,000.
2. Each fiscal year the City will provide $100,000 to be awarded in private sewer main or lateral
repair or replacement grants. Any funds remaining at the end of each fiscal year shall roll over to
the next fiscal year. Because funds are limited, it is possible that not every eligible applicant will
receive a grant. Persons not awarded a grant due to unavailability of funds may reapply the
following fiscal year. Each property owner is eligible for no more than one private sewer main or
lateral repair or replacement grant.

City of Pacifica Sewer Lateral Replacement Program:
Program Guidelines
Background
The City of Pacifica municipal code requires that property owners or persons in possession of
property properly maintain side, or lateral, sewer lines connecting privately-owned buildings to
the City’s main sewer lines at the owners’ own costs.
On Oct. 17, 2011, City of Pacifica will begin their Sewer Lateral Replacement Program
(“Program”) to enable the City to (a) inspect potentially defective, leaking and/or failed laterals
connecting private residences to the City’s main sewer line, and (b) offer grants to reimburse
property owners a portion of the cost of replacing qualifying defective, leaking and/or failed
laterals. The Program will focus on areas that have shown to have the highest storm water
infiltration based on flow studies that were done last winter. Those studies showed the highest
infiltration rates in the lower Linda Mar area followed by Pedro Point, Vallemar and Fairway Park
(both East & West Fairway).
Eligibility
To be eligible for a lateral inspection under this Program:
1. the property must be a private, single-family primary residence or the property must be
owned and operated by a nonprofit organization, on a not-for-profit basis, as temporary
or transitional housing or related services for homeless persons;
2. the property must not have already received benefits through this Program;
3. the lateral must be at least ten years old or there must be a reasonable basis to believe
that the lateral is defective, leaking and/or failed, as determined by City staff.
To be eligible for a grant for lateral replacement reimbursement under this Program:
1. the above criteria for lateral inspection must be met;
2. the lateral must have been inspected through this Program;
3. the lateral must have been found by City staff to be leaking due to root infiltration,
breaks, cracks, failed pipe, “Orangeburg” pipe, or alignment problems;
4. the property owner must submit evidence that the lateral has been replaced in
conformance with current City codes and specifications, including receipt of required
permits, by a contractor licensed to perform such replacement;
5. the property owner must submit evidence of full payment to the contractor.
Award Limits
For each grant given under this Program, reimbursements are limited to $1,000 per property.
When the City has reached the maximum budget for the Program in any fiscal year, the
Program may be suspended until further funds are available. When the City has reached the
maximum aggregate budget for the Program, the Program may be terminated.

Lateral Replacement Grant Program Guide
An Innovative Program to
Protect Human Health & the Environment
Ross Valley Sanitary District
The Ross Valley Sanitary District Board of Directors approved the
Lateral Replacement Grant Program on August 25, 2009.
Dear Customers:
Thank you for helping us protect the community by repairing your end of the pipe!
As you may have learned, nearly 50% of all sewer spills are caused by leaky lateral pipes on
private property. This program is designed to help encourage property owners like you to
repair your pipe and help protect our environment.
Here is how to take advantage of our innovative grant program:
•The District will fund either $4,000 or half of the total cost of the lowest bid to
replace your lateral pipe, whichever is less.
•Three bids from any of the District’s pre-qualified contractors must be submitted
to the district along with a DVD of the lateral inspection performed by a
contractor and observed by a District Inspector. You will need to coordinate the
video recording of your damaged pipe with our district staff so we can be on hand
for the inspection.
•Once the inspection is completed and you have your DVD and bids, you’ll
submit them to the district along with our Lateral Grant Application.
•The district will review the DVD, bids and your application then notify
you about the status of your grant funding request.
A flow chart of these steps, an application and a list of pre-qualified contractors is included
on the following pages. Contractors who are interested in being added to the list should con-
tact the District or the local builder’s exchange.
Many contractors already understand the program and can assist you in applying for it.
Naturally we are more than happy to assist you as well.
Please contact us with your questions.
Sincerely,
Brett Richards

Sewer Lateral Test Ordinance 1329
MUNICIPAL CODE SECTION 15.12.110
Click here for Sewer Lateral Ordinance Test Results
PRIVATE SEWER LATERAL AND TESTING PROCEDURE AND REQUIREMENTS
Ordinance No. 1329, which was adopted July 7, 1986 and became effective August 7, 1986 and was modified by Ordinance 1623
on March 23, 2000, requires the abatement of sewer laterals and cleanouts which are found to contain leaks or separations;
laterals covered are from the building served to the cleanout in the City right-of-way. The ordinance also requires the testing and
repair of laterals prior to the sale of the property if the building was constructed 25 years or more before the date of sale. Date of
construction shall be the date the Building Permit was finaled. In addition, testing is required if two (2) or more plumbing fixture
units are added to a property. The following procedures and requirements are adopted to implement Ordinance No. 1329.
It shall be the owner's responsibility to determine if testing is needed. Contact the Building Department to determine the age of
the structure and if the lateral had been tested and/or repaired within the past ten (10) years. It can be assumed that testing and
repairs have not been done unless the property has been sold after August 1986. If the lateral needs testing, the property owner
shall obtain a contractor or plumber to perform the test. The test shall be performed as follows:
The test must be witnessed by a City representative to meet the ordinance requirements. The contractor or owner shall
first obtain an Encroachment Permit from the Public Works Department in City Hall and pay the $303 testing fee.
Obtaining the permit can be done before or concurrently with scheduling an appointment but is required at the time of the
test. All arrangements and set up should be completed by the time the City representative arrives to witness the test. Call
(650) 558-7670 to schedule an appointment.
Each lateral is to have a cleanout located in the City right-of-way. If a cleanout does not exist, then one is required to be
installed. The private owner's contractor will install the cleanout with an Encroachment Permit from the Department of
Public Works. City personnel will spend a limited amount of time to assist in locating the cleanout or lateral. A cleanout
located adjacent to the building will be a help in testing and repairing and is also required by the Uniform Plumbing Code.
A Plumbing Permit from the Building Department is required for the cleanout adjacent to the building or for any work done
on private property.
Testing will be accomplished by either a water exfiltration test or an air test. The air test shall be used in hillside areas
where the hydraulic head pressures could damage the pipe.
Water Exfiltration Test: The contractor shall furnish all materials and equipment, except the calibrated bucket. The
contractor shall plug the lateral and riser at the City cleanout and then surcharge the line with water to a point equal to
the foundation grade (floor joist level) or slab floor level. The minimum height of the water level shall be two feet (2'-0")
above the lateral at the City cleanout. If there is any fixture inside the structure lower than the testing water level, the
contractor shall have to either plug the fixture or the lateral at the building. An approved backwater valve shall be
installed if there are any plumbing fixtures below the level of the City cleanout. A Plumbing Permit is required for this
work. The contractor may also install or use an existing cleanout near the structure at the foundation grade (floor joist
level) or slab floor level to establish the minimum two feet (2'-0") water level. (See Standard Drawing No. SS-2_3) [pdf]
The lateral shall be surcharged for 30 minutes and the amount of water lost shall be measured. The lateral shall be
considered acceptable if the amount of water lost is less than four (4) gallons. No increase or allowance is allowed for long
laterals or for laterals larger than the 4-inch minimum size.
Air Test: The contractor shall furnish all materials, equipment and labor for making the test, except the pressure test
gauge. Air test equipment shall be approved by the City. The contractor shall clean pipe and plug the lateral at the
building line and the City cleanout. (If a cleanout is within two feet (2'-0") of the building, the lateral may be plugged at
the cleanout.)
The leakage test of the lateral shall be conducted in the presence of the City in the following manner:
Air shall be slowly supplied to the plugged lateral until the internal air pressure reaches 4.0 pounds per square inch greater
than the average back pressure of any groundwater that may submerge the pipe. The air pressure shall be regulated by a
suitable regulator valve.
At least two minutes shall be allowed for temperature stabilization before proceeding further. The rate of air loss shall
then be determined by measuring the time interval for the internal pressure to decrease from 3.5 to 2.5 pounds per
square inch greater than the average back pressure of any groundwater that may submerge the pipe.
The lateral shall be considered acceptable if the time interval measured for the internal pressure to drop from 3.5 to 2.5
pounds per square inch is 10 seconds or greater. Air test data is on Standard Drawing No. SS-2-4. [pdf]
If the lateral passes the test, it shall be certified as acceptable and the sale can take place without any further action. The
certification shall be placed in the Building Department file. This certification shall be effective for ten (10) years.
If the lateral fails the test, the lateral shall be either repaired or replaced and retested until the lateral passes. There will
City of Burlingame CA : Sewer Lateral Test Ordinance 1329 http://www.burlingame.org/Index.aspx?page=351

be a $10 fee for the second retest and each retest thereafter, payable at the Department of Public Works. A Plumbing
Permit will be required for any repairs or replacement. A complete replacement from building to City cleanout is effective
for 25 years. A repaired and tested lateral is effective for ten (10) years.
The City neither has nor will make any determination as to who will pay for the testing and repairing. That is to be decided
between the parties involved in the sale.

Sewer Lateral Compliance Plan ‐ 3
Section 1 – Purpose and Applicability
Overall this plan will reduce the leakage of sewage into public receiving waters and the
infiltration and inflow (I & I) of storm, ground and tidal waters from private laterals into
the City of Richmond’s (COR) publicly owned sanitary sewer collection system.
The primary result of a poorly operating or failed lateral allowing I & I is hydrological
overloading (surcharging) of the COR sanitary sewer collection system during rain
events contributing to sanitary sewer overflows. Additionally, the lack of their integrity
promotes ex-filtration causing standing sewage on private and public property,
discharges of sewage to the storm drains, public health, general nuisance and wellbeing
problems. There are approximately 18,000 private laterals in the Richmond Municipal
Sewer District, an estimated 2721 miles in total length. Following the guidelines from
the California Regional Water Quality Control Board, San Francisco Bay Region
(CRWQBSFB) Resolution number R2-2005-0059, “In Support of Program for Inspection
and Rehabilitation of Private Sewer Laterals,” and the direction of CRWQCBSFB
Resolution Number R2-2003-0095, “In Support of Collaboration between the Regional
Board and Bay Area Clean Water Agencies to Report and Manage Sanitary Sewer
Overflows,” is the purpose of this plan, and to collectively maintain the beneficial use of
all receiving waters.
The purpose of this plan is to establish fair and consistent policies and procedures for
the testing, repair, and replacement of all defective sewer laterals. To effect the
purposes of this plan, the COR may enter upon private property for inspecting, testing,
and repair of the sewer laterals.
A sewer lateral is defined as the portion of the sewer serving a property starting at the
structure or building and running to and including the connection to the COR’s main line.
The sewer lateral is owned by the property owner, who paid for the installation and
therefore is also responsible for its maintenance and repair; at no time has the COR
accepted transfer of the ownership of a private lateral. This plan does not reduce,
negate, change, modify, or eliminate this basic understanding.

Section 3 – Compliance Inspection
Testing may be accomplished by either a water ex-filtration test or an air test or Closed
Circuit Video recording observation. If a Closed Circuit Video recording observation is
selected as the preferred method of inspection then the video shall meet the following
requirements:
1) shall be in DVD format
2) shall be in color (any black & white, cloudy, fuzzy, or otherwise unclear video
will be returned for resubmission)

At the City Engineer’s discretion, the video may be returned for resubmission in
accordance with the above requirements if any of the above requirements are not
strictly adhered to. The selected inspection method can be performed by contractors
who have a current state license. The City Engineer will notify the property owner(s) and
tenants regarding when a sewer lateral inspection is required except when it is required
due the sale of property, otherwise the inspection is initiated as part of all applicable
sections of Richmond Municipal Code Chapter (RMC) 12.17. The inspection of the
lateral may be initiated by any of the following:
● Capital Improvement Project Sewer Rehabilitation
The project-by-project inspection program will not preclude the COR from testing sewer
laterals in conjunction with other projects anywhere in the City of Richmond. It does not
preclude a property owner from testing their sewer lateral at any time and making
repairs at their expense.
9/30/2011
Sewer Lateral Compliance Plan ‐ 7
● Repair of the Sewer Lateral
Whenever a sewer lateral fails during normal usage or is broken into before making any
repair to the sewer lateral.
● Sale of Property
Whenever a property is to be sold or there is a transfer of title, a sewer Certificate of
Lateral Compliance” must be obtained. The procedures herein must be followed by the
property owner to obtain a Certificate of Lateral Compliance.
● Upgrades and Remodeling
Whenever property located in the City of Richmond is remodeled to include the addition
of two or more plumbing fixtures that discharge into a sanitary sewer system, the sewer
lateral(s) to the property shall be tested. Before final building inspection, all repairs or
replacements necessary to bring a lateral into compliance shall be performed.
● Issuance of a Building Permit
When a building permit is issued by the City or County requires compliance with all
applicable Codes
● Evidence of a improper sewer connection
Failure of the property owner to comply with RMC section 12.17.020 or 12.17.040 may
require them to conduct testing by direction of the City Engineer and obtain a Certificate
of Lateral Compliance at anytime. (RMC12.17.080)
● Home Owners Associations and Cooperatives
The City of Richmond Engineering Division has become aware of the need to clarify
sanitary sewer lateral inspections as it relates specifically to Homeowners Associations
and Cooperatives during property sales. Each property owner is responsible for
obtaining a Certificate of Lateral Compliance of a single family dwelling, or an
arrangement between the property owners and the cooperative or homeowners
association for ensuring compliance in the stated regulatory time frames for property
sales will need to be provided to the City Engineer. If the lateral is jointly shared then
an arrangement between the property owners and the cooperative or homeowners
association for ensuring compliance in the stated regulatory time frames for property
9/30/2011
Sewer Lateral Compliance Plan ‐ 8
sales will need to be provided to the City Engineer. The mains servicing the
development will need to be tested every fifteen (15) years by an arrangement between
the property owners and the cooperative or homeowners association. All arrangements
between the cooperative or homeowners associations for compliance of this ordinance
need to be on record with the City Engineer.
As of March 20, 2007 arrangements between the property owners and the cooperative
or homeowners association for ensuring compliance in the stated regulatory time
frames for property sales will need to be provided to the City Engineer for review by
April 1, 2008. After a satisfactory review and approval of the arrangement the lateral
inspections and any subsequent repairs or required unified plumbing updates need to
be completed and the Certificate of Lateral Compliance obtained no later than April 1,
2009 and every fifteen year thereafter.
● Waiver of Inspections:
1. The house/dwelling/structure lateral was constructed within the last 15 years, and a
Certificate of Lateral Compliance was obtained within 5 years of its construction.
2. The lateral was completely replaced within the last 5 years.
(have the receipts/invoices from the contractor that show the repair/replacement
done.)
3. Have previously obtained a Certificate of Lateral Compliance
The waiver of inspection still requires the issuance of a Certificate of Lateral
Compliance to record the 15 year inspection requirement in the City’s database.
9/30/2011
Sewer Lateral Compliance Plan ‐ 9
Section 4 – Compliance
The sewer lateral will be evaluated based upon a review and evaluation of the test
results. COR designated staff will perform this evaluation and determine if the lateral
complies with RMC 12.17.070, “Lateral Certification.” Broken pipe, offset and/or
distorted joints, root intrusion, lack of cleanouts, all constitute deficiencies that do not
comply with Standard Specifications and will require either repair or replacement.
Repairs or replacements will be required prior to the close of escrow in the case of
property transfer, or within one month of the lateral test results.
● Properties in escrow
The COR has no intention of holding up sales transactions for properties in escrow.
However, an extension of 60 days to obtain a Certificate of Lateral Compliance will be
verbally granted by the City Engineer on a case by case need. The extension is
documented in the escrow addendum. The property owner is responsible to ensure the
documentation occurs stating who will complete the compliance action and the
timetable of compliance. Generally monies can be left in escrow by the seller to pay the
contractor’s fees for any necessary repairs.
If the buyer elects to assume all responsibility for obtaining a Certificate of Lateral
Compliance a notarized letter or a statement in the escrow addendum stating that the
requirements will be met sixty (60) days after the close of escrow is necessary.
A copy of the signed addendum or notarized letter must be received by the City
Engineer’s office no later than the close of escrow.
● Upgrades and Remodeling Extension
Currently extensions of up to one year to complete this requirement for upgrades or
remodeling are available upon approval by the City Engineer. This is the responsibility
of the property owner.
9/30/2011
Sewer Lateral Compliance Plan ‐ 10
Section 5 – Lateral Work
The property owner shall be responsible for making any and all repairs and
replacements of the sewer lateral. All work shall be done according to standards in the
latest edition of the Uniform Plumbing Code as adopted by the COR in its Standard
Specifications and Drawings, and any standards issued by the City Engineer. Repairs
must bring the lateral into full compliance with these standards.
● Shared Sewer Lateral Corrections
General:
When any repairs or replacements are done to those laterals that are jointly shared
by more than one building or structure from different properties, each shall require a
discrete connection to the City’s sanitary sewer main as part of the repair. If a
property with two buildings or structures with plumbing fixtures requiring drainage is
subdivided, each building or structures shall require a discrete connection to the
City’s sanitary sewer main as a condition of subdividing (RMC 12.17.050). At the
discretion of the City Engineer a statement of agreement between the subject
property owners will be filed with the escrow/title company, County Clerk or on
record with the deed stating who is responsible for any necessary repairs as
required by RMC. This statement of agreement, approved by the City Engineer can
supersede the requirement to install discrete connections.
If the sewer lateral is shared with other properties or structures, the necessary
repairs, separation of the system, or relocation of the system will be as approved by
the City Engineer.
Such work shall be done according to standards issued by the City Engineer, and in
the latest edition of the Unified Plumbing Code and COR’s Standard Specifications
and Drawings.
Exceptions:
If a letter of agreement exists with the property deed explaining that joint
responsibilities between property owners or the following:
The City will need to have a record of the notarized agreement that is filed with the
finalized deed. It is recommended the agreement should at least state:
1. The location of any private easement on the subject easement property
2. What section or sections of the joint lateral each property owner is responsible to
individually maintain and pay associated costs.
9/30/2011
Sewer Lateral Compliance Plan ‐ 11
3. What section or sections of the joint lateral that the maintenance and associated
costs are shared by both or all involved parties.
4. The duration of the agreement
5. The right to terminate the private easement agreement in writing and within a
reasonable timeframe for the purpose of property improvements or plumbing
relocation by the subject private easement property owner.
● Backflow valve or overflow device required
When any repairs are done to lateral that does not have an existing backflow valve or
overflow device, the property owner shall install the appropriate valve or device. It shall
be the responsibility of the property owner to maintain the backflow valve or overflow
devise in proper operating condition (RMC 12.17.050).
9/30/2011
Sewer Lateral Compliance Plan ‐ 12
Section 6 – Fee, Permits and Inspections
● Permits
The property owner, or property owner’s contractor, must obtain a Sewer Permit from
the COR before any work is done on sewer laterals. Failure to obtain the Permit shall
subject the property owner to a monetary penalty as set forth in the Richmond Municipal
Code and/or such further and different penalties as set forth by the City Engineer. The
property owner is responsible for obtaining permits. Encroachment Permits from the
City Engineer may also be needed if any work is performed in the public right-of-way.
● Inspection
Inspection procedures and requirements shall be according to standards issued by the
City Engineer and the COR’s Standard Specifications.
The City Engineer can require the inspection of a lateral at any time in order to protect,
sewage from entering receiving waters.
● Right of entry
The City Engineer will give written note to property owner and occupants ten (10)
business days to prior entering the property in order to conduct an inspection, or collect
wastewater samples and test any buildings, structures, or premises to secure
compliance or prevent a violation. (RMC 12.17.120)
● Fees
Fees and charges for the Permit, inspection, penalties, and issuance of “Certificates
Lateral of Compliance” shall be in accordance with the City’s fee and rate schedule.
This lists of all city services, penalty associations, interest, permit fees, and hourly
personnel and equipment rates and is kept on file with the City Clerk.
9/30/2011
Sewer Lateral Compliance Plan ‐ 13
Section 7 – Certification of Sewer Laterals
● Certificate of Lateral Compliance
A Certificate of Lateral Compliance will be issued by the City Engineer when a lateral
complies with Specifications as determined upon completion of a successful test.
The City will maintain a record of all certificates issued, including the date of issuance. A
Certificate will be valid until subsequent testing is performed and a new Certificate
issued for the following periods of time:
● Point of Sale
Not to exceed fifteen (15) years or more if constructed before this period of time. The
COR has no intentions of holding up the escrow process, and will allow extension of up
to 60 days past the close of escrow.
● General Requirements
All properties shall be tested by the property owner at a minimum fifteen (15) years
unless the dwelling was a new construction within the previous two years.
A Certificate of Lateral Compliance will be issued after a sewer lateral has been
satisfactorily tested, without repair, or repaired and/or replaced. This Certificate will be
valid until a subsequent inspection is performed and a new Certificate issued, or fifteen
(15) years which ever comes first. Certificates will be filed with the COR Engineering
Services Department.
● Exceptions
If the property construction was completed and signed off within the last two (2) years
the certificate is issued at no cost since the fees were collected with the construction
permit.

Section 8 – Long Term Compliance
It is the intent of the COR that the testing, repair, and replacement of the sewer laterals
are a continual and ongoing program. The COR may, at any time, evaluate the level of
infiltration and inflow from properties and, if it is determined that excessive infiltration
and inflow exists, all sewer laterals within the property requires compliance with
applicable RMC.
Section 9 – Appeal of City Engineer’s Assessment
All decisions of the City Engineer can be challenged in writing to the City Engineer
within two (2) days prior to the date required to complete the inspection and or repairs
and or subsequent citations. The appeal must be in writing and must state the basis of
the appeal.
Section 10 – Failure to Comply
● General
Should any property owner(s) fail to repair or replace their sanitary sewer lateral within
the time limits set forth by Section 7, the City Engineer is hereby authorized to proceed
with all necessary work to bring the lateral in compliance, including but not limited to
hiring of contractors, and entering upon private property.
Section 11 - Notification to Property Owner
Prior to proceeding with the necessary work, the City Engineer shall notify the owner of
the intent to proceed with such work. Such notice shall be served personally on the
owner or by mailing such notice to the owner addressed to the post office address last
shown on the Contra Costa County secured assessment rolls, and by positing a copy of
such notice on the property. Notice shall be given at least ten (10) days prior to the
commencement of the work. No further notice need be given. (RMC 12.17.120)

Section 18-5 ABATEMENT OF IMPROPER SEWER CONNECTIONS.
Subsection 18 -5-11 Private Sewer Lateral Testing Procedure and Requirements.
The property owner, or his/her appointed contractor shall obtain a plumbing permit for sewer lateral
testing prior to commencing with the testing procedure. The test procedure shall be performed as
follows:
a. Each lateral is to have a two -way cast iron clean-out, as shown on Standard Drawing 8396-34 or
8397-34, located in the City right-of-way, on private property adjacent to the City right -of-way, or on a
Public Utility Easement. If one does not exist, a clean-out shall be installed prior to performing any
testing. Installation of the clean-out, if necessary, shall require a plumbing permit; shall be run to grade
and covered by a meter box and lid as detailed on standard drawing 8396-34. A clean-out located
adjacent to, (within 30" inches), the building will be a help in the test and repair of the lateral and is
required by the Uniform Plumbing Code for any new construction.
b. The test must be witnessed by a City Inspector. All arrangements and set up should be completed
by the time the City Inspector arrives to witness the test.
c. Testing may be accomplished by either a water exfiltration test or an air test.
1. Water Exfiltration Test. The owner's contractor shall furnish all materials and equipment at
owner's expense, except the calibrated bucket. The contract shall plug the lateral and riser at the City
clean-out, and surcharge the line with water to a point equal to the foundation grade (floor joist level) or
slab floor level. The minimum height of the water level shall be two (2') feet above the lateral invert at
the City clean -out. If there is any fixture inside the structure lower than the testing water level, the
contractor will have to either plug the fixture or the lateral at the building. An approved backwater valve
must be installed if there are any plumbing fixtures whose level is below the City clean-out. A plumbing
permit is required for this work.
The lateral shall be surcharged for thirty (30) minutes and the amount of water lost shall be measured.
The lateral shall be considered acceptable if the amount of water lost is less than four (4) gallons for a
four (4") inch lateral. On an individual basis, the amount of allowable water loss may be adjusted by the
City Engineer for a six (6") inch diameter lateral, or unusually long lateral lengths. See Standard
Drawing 8277-32, available from the City Engineer, for a visual procedure reference.
2. Air testing shall be conducted in accordance to Section 306-1.4.4 of the Standard Specifications
for Public Works Construction, American Public Works Association, latest edition, with the exception
that "Engineer" shall be replaced with "City Inspector" and "Contractor" with "Owner's Contractor"
respectively. (Ord. No. 2404 N.S.; Ord. No. 2533 N.S. §21)

Oakland CA sewer lateral EBMUD waste
water control ordinance
October 21st, 2010
Update as of May 2011
As a home seller in Oakland or Piedmont California you will soon be obligated to conduct a sewer
lateral scope inspection and upon transfer of the home to a new Buyer someone will be obligated
to make any repairs needed to comply with the new city of Oakland sewer lateral ordinance and
the EBMUD waste water ordinance. If you are a Buyer considering a home prior to January 1,
2011 you would be well advised to perform your own camera inspection to make sure that you
are not unwittingly assuming someone else’s very expensive problem.
A number of East Bay Cities and Sanitary
Districts require that sewer laterals be
inspected and brought into conformance as
a part of the sale of property. A recent
court order will require the cities of
Oakland, Emeryville, Piedmont, Berkeley,
Alameda, Albany, Kensington, El Cerrito
and the Richmond Annex of the City of
Richmond to require homeowners to fix or
upgrade their sewer lines when a home is
sold or upgraded. The East Bay Municipal
Utility District (“EBMUD”) Wastewater
Control Ordinance will require property
owners in certain areas of the EBMUD
wastewater service area to obtain a
compliance certificate that shows their
private sewer laterals are without defects
and have proper connections. The private
sewer lateral program requirements for
property owners will be in effect on January
1, 2011. The ordinance specifies three
conditions which require property owners
to test and, if needed, repair or replace
their private sewer laterals:
1-Prior to selling the property
2-When obtaining any permit from the construction or modification of the property estimated to be
greater than $100,000
3-When increasing or decreasing EBMUD water service that requires a change in meter size.
These EBMUD requirements will only affect properties in the EBMUD wastewater service area in
Emeryville, Oakland, and Piedmont. The cities of Alameda, Albany, Berkeley and the Stege
Sanitary District (which serves KensiSellers and Buyers are advised to check with the local
Building Inspection Department or Sanitary District for more information.

Spring Street Phase I and II Lateral Rehabilitation: I&I Reduction Effectiveness Study
Page 1
1 EXECUTIVE SUMMARY
V&A has completed an Infiltration and Inflow (I&I) Reduction Effectiveness Study for the East Spring
Phase 1 and Phase 2 Lateral Rehabilitation and Replacement Project. The District performed
improvements to lateral sewers in the neighborhoods around East Spring Street during the summer of
2007. The purpose of this pilot study was to measure and analyze the pre-construction and post-
construction dry weather and wet weather flows at three locations immediately downstream from the
majority of the targeted construction zones. V&A was tasked to perform I&I analysis to differentiate
base flows from I&I flows, and conduct synthetic hydrograph analysis to determine the I&I response
factors at the three locations. These pre-construction and post-construction response factors were
compared to determine the percentage of I&I reduction achieved by the East Spring Street Phase 1
and 2 I&I Reduction Projects.
Pre-construction flow monitoring was conducted over a 3.5-month period from December 1, 2006
through March 15, 2007. Post-construction flow monitoring was conducted over a 2.5-month period
from December 18, 2008 through March 10, 2009. The East Spring Street Project limits and the
three flow monitoring sites are shown below in Figure 1-1.

1.1 Results Summary
The flow metering data and rainfall data acquisition was successful. Flows and rain data were
obtained and precise I&I hydrograph response components were calculated. For this analysis, the I&I
components were applied to a 10-year, 24-hour storm event as a means for determining a metric
standard by which to estimate total I&I reduction.
The results from the synthetic I&I hydrograph and 10-year design storm event are shown in Table
1-1, and are illustrated in Figure 1-2, Figure 1-3 and Figure 1-4.

Total Seasonal Effects: Over the course of the flow monitoring period, which spanned a majority of
the wet weather season, approximately 15.8 inches of rainfall was measured in the East Spring Street
region between December 18, 2008 and March 4, 2009. The total gallons of I&I that did not enter the
collection systems as a result of the East Spring Phase 1 and Phase 2 Lateral Rehabilitation and
Replacement Project is estimated in Table 1-2. Note: the 2008/2009 rainfall season totals were less
than seasonal averages.

2 INTRODUCTION
V&A was retained by Winzler & Kelly Consulting Engineers (W&K) to perform post-construction
sanitary sewer flow monitoring and inflow and infiltration (I/I) analysis for the East Spring Phase 1 and
Phase 2 Lateral Rehabilitation and Replacement Project. The post-construction flow monitoring and
analysis completed an Infiltration and Inflow (I&I) Reduction Effectiveness Study for the East Spring
Phase 1 and Phase 2 Lateral Rehabilitation and Replacement Project that started in 2007.
Pre-construction flow monitoring was conducted during the 2006/2007 wet weather season to
establish I&I response curves specific to the three site locations shown in Figure 1-1. The District
performed improvements to lateral sewers in the neighborhoods around East Spring Street during the
summer of 2007. V&A was tasked to perform post-construction flow monitoring and I&I analysis at
the same flow monitoring locations to establish the new (post-construction) I&I response curves. The
pre-construction and post-construction response factors would be normalized to a 10-year, 24-hour
design storm event and compared to determine the percentage of I&I reduction achieved by the East
Spring Street Phase 1 and 2 I&I Reduction Projects.
The post-construction flow monitoring was conducted over a 2.5-month period from December 18,
2008 through March 10, 2009.
Detailed descriptions of the individual flow monitoring sites, including photographs, are included in
Appendix A.

3.1 Rainfall
Rainfall information was taken from a centrally located rain gauge that V&A installed within the Alta
Heights Elementary School (Refer to Figure 1-1 for rain gauge location). Figure 3-1 graphically
displays the rainfall events recorded over the flow monitoring period (December 18, 2008 through
March 8, 2009).

Figure 3-2. Rainfall Accumulation Plot
The historical average rainfall is shown for comparison to the rainfall that occurred over the course of
the flow monitoring period (December 18, 2008 through March 8, 2009). The historical data was
taken from the Western Regional Climate Center (WRCC) at Station 046074 in Napa, California.
Rainfall data from the years 1970 through 2000 were used to determine these averages. The
historical average over the monitoring period is 13.32 inches. The rain gauge indicated a rainfall total
of 16.06 inches, approximately 121% of normal levels for this period of time.
It is noted that a majority of the rainfall for the year occurred within the monitoring period. The total
rainfall for the entire season (July 1, 2008 through June 30, 2009) was less than average.
3.2 Flow Monitoring and I&I Results
Baseline flow determination and I&I analysis to differentiate base flows from I/I flows was conducted
per the methods described in the Flow Monitoring and I&I Study Final Report that was submitted in
conjunction with this document. Flow monitoring results are presented in Appendix A for the three
flow monitoring sites that are included in this study.

3.3 Synthetic Hydrographs
In order to model design storms, synthetic hydrographs were developed to approximate the actual
rainfall dependent I&I (RDI&I) hydrograph shape in terms of parameters representing time to the peak
and the recession coefficient. The actual RDI&I hydrograph was best matched with a synthetic
hydrograph by separating the synthetic hydrograph into seven volume components (R1, R2, R3, R4,
R5, R6, R7). The seven components represent different response times to the rainfall event and
different infiltration or inflow paths into the sewer system. R1 is characterized by a short response
time and is assumed to consist of mainly inflow. R7 represents slower response and longer recession
times and consists of mostly infiltration. Levels of soil saturation are also considered. Using synthetic
hydrograph analysis, appropriate time and recession parameters were estimated by a trial-and-error
procedure until a good match was obtained. A sample synthetic hydrograph and its component
hydrographs for the period of February 14 to 28, 2009 for Site 1 is shown in Figure 3-3 (post-
construction). The pre-construction synthetic hydrograph and its component hydrographs for the
period of February 8 through March 3, 2007 for Site 1 is shown in Figure 3-4.

3.4 Design Storm
With I&I components defined, design storms can be applied and the resulting I&I flows can be
predicted. The design storm used for this analysis was a 10-year storm event taken from the NOAA
Western U.S. Precipitation Frequency Maps.
Figure 3-5 summarizes the design storms per hour and shows the storm profile for the 10-year event.
This particular profile distribution also fits the criterion for a 2-hour, 6-hour and 24-hour event.

3.5 Synthetic Hydrograph Comparison: Reduction of I&I
The 10-year design storm event was applied to both sets (pre- and post-construction) of I&I
components to obtain an appropriate comparison between 2007 and 2009 storm event responses
and determine the effectiveness of the I&I rehabilitation.
The results from the synthetic I&I hydrograph and 10-year design storm event are shown in Table
3-1, and are illustrated in Figure 3-6, Figure 3-7 and Figure 3-8.

Total Seasonal Effects: Over the course of the flow monitoring period, which spanned a majority of
the wet weather season, approximately 16.06 inches of rainfall was measured in the East Spring
Street region between December 18, 2008 and March 4, 2009. The total gallons of I&I that did not
enter the collection systems as a result of the East Spring Phase 1 and Phase 2 Lateral Rehabilitation
and Replacement Project is estimated in Table 3-2. Note: the 2008/2009 rainfall season totals were
less than seasonal averages.
