Q
Subject: Swim Center Improvement CIP - project priorities, funding,
and Hi-Rate Filtration System plans and specifications.
C.A.O. RECOMMENDATION:
1. By motion, approve Alternative 1 for reprioritization and funding of
CIP Swim Center Improvement Projects, in order to fund the Hi-Rate
Filtration System in FY 1991-92 as previously directed by Council.
2 . By motion, approve plans and specifications for "Swim Center
Improvement Project, Media Hi-Rate Filtration System, " City Plan No.
S-24X, and authorize soliciting of bids and contract award by the
CAO, if the lowest responsible bid is within the Engineer' s cost
estimate.
DISCUSSION
Reprioritization
The CIP Item for "Swim Center Improvements" includes six distinct
projects that were proposed to be constructed in FY 1991-92 (Pool cover
replacement, $15, 000; Alarm system replacement, $36, 000; Tot pool
dressing room $28, 000; and bank stabilization $30, 000) and FY 1993-94
(High-rate sand filtration, $84, 000; and Ozonation equipment $27, 000)
During review of the draft budget, Council indicated that these
projects should be reprioritized to complete the filtration and
ozonation projects earlier than proposed. The funds appropriated for
FY 1991-92 ($109, 000) and planned for FY 1993-94 ($111, 000) did not
reflect changes in priorities.
In response to the comments from City Council the recommended order of
priorities is:
1. Pool cover replacement project $10,948. 08 (completed)
Annual savings are estimated to be $40, 000 per year in water,
natural gas and chemicals
2 . High-rate sand filtration $84, 000
This project is eligible for a PG&E rebate of $6, 077 and will
save $17, 000 annually on the cost of water, electricity,
chemicals, filtering materials and labor. This project is
ready to go to contract.
3 . Alarm system replacement $36, 000
This is an important project in terms of Swim Center Security.
The current alarm system is over 10 years old and is no longer

reliable resulting in numerous false alarms. Design of this
project could be completed by the end of summer.
4 . Ozonation equipment $27, 000
With ozonation Public Health standards can be met with less
chorine. This will improve the quality of water and will
reduce the amount of chlorine needed at the Swim Center.
Ozonation will reduce operating costs approximately $1, 200
annually. Development of plans and specifications is in the
very early stages.
In addition to this project there is a need to modify the Swim
Center to contain a leak within the room or cabinet where the
chlorine is stored. The Uniform Fire Code, 1988 edition, M.C.
15.08.010 was modified since the Swim Center was constructed.
Reducing the amount of chlorine on site will reduce the size of '.
the containment facility. The amount of chlorine needed on
site and the scope of the containment facility will be defined
along with the design on this project. A request to modify
this project or to establish an additional CIP project will be
submitted when the need is defined. The Fire Department
concurs that this project is needed ("the sooner the better") .
5. Tot pool dressing room $28, 000
This project is proposed in order to provide separate changing
areas for parents with very young children. Plans are complete ;
and specifications are about complete.
6. Bank stabilization $30, 000
The banks on which the solar collectors are mounted are not
protected. Although this needs to be accomplished soon, in
order to assure the operation of the collectors, this is the
lowest priority of the six projects. i
This listing gives priority to cost avoidance, safety and security.
Fundinc
After the projects are reprioritized, the funding for each fiscal year
must be established. Either of two alternatives would be appropriate.
I
Alternate 1
The simplest change would be to accept the priorities and use the
existing funding. This does not fully respond to the previous
instructions of Council. The Projects would be scheduled as follows:
1991-92 Pool cover $11, 000
High-rate sand filter 84, 000
design work on some. of
the following projects 3 . 000
$ 98, 000

Alternate 2
The priorities would be in the order recommended above. Funding would
be accelerated by an increase of $77, 000 in FY 1992-93 . The FY 1993-
94 CIP program would be reduced by the same amount. This provides
substantial public safety benefits as well as significant operating
cost savings. The schedule would be as follows:
1991-92 Pool cover $111000
High-rate sand filter 84, 000
design work on some of
the following projects 3 , 000

1993-94 Bank stabilization $ 30 , 000

Filtration Proiect
Both alternatives provide for the upgrade of the filtration system
during the current fiscal year. The project is ready to go to bid.
Replacing the diatomaceous earth filters with rapid rate sand filters j
will provide higher levels of filtration at lower costs. The increased
filter capacity is also required to support the ozone system which will
be the second. part of the filtration and sanitization improvements.
The life expectancy of the new filtration system is 20 years.
Operational cost savings and a PG&E rebate are expected to repay the
investment within five years. The savings include:
Electricity savings of 101, 000 KWH per year. The new filters
accomplish the task with fewer hours of operation. ($9, 116
annually, non-escalated 1992 dollars)
A PG&E rebate of $6, 077 . 52 if the project is completed by June 1992 .
Pump repairs will be reduced by $700 per year because pumps will be
operated fewer hours.
Annual replacement of filter elements and media will be eliminated
resulting in a savings of $6, 500 annually.

Overtime will be reduced by $300 per year as the new filters can be
cleaned while the pool is in operation.
The final result will be a cleaner pool for less money.
FISCAL IMPACT
Reprioritization
In light of the City's current financial situation, staff recommends
Alternative 1 in order to stay within the funding planned in the FY
1991-93 Financial Plan.
Alternative 2 would spend the $77, 000 one year earlier than projected
in the Financial Plan. Total expenditures between now and the end of
FY 1993-94 would be the same for either alternative.
Filter Replacement Project
Engineer's Cost Estimate 84, 000 without contingencies
Funding in the amount of $84, 000 is included in CIP Swim Center
Improvements (FY 1991-93 Financial Plan pages E-9 and E-20) . The
reprioritization of the six distinct projects within this CIP provides
for funding this project from the $109, 000 appropriated in FY 1991-92 .
