COUNCIL AGENDA REPORT " NUMB
From: Dave Romero Via: W. T. Hetland Prepared by: Chip Short
P.W. Director Utilities Manager OT� Water Treatment Plant Sup.
Subject: City-wide Telemetry System
Recommendation: By motion approve purchase of telemetry hardware for the water
treatment plant, a small portion of the water distribution
system, Whale Rock Reservoir and the sewer collection system.
BACKGROUND
Presently the City of San Luis Obispo operates a waste water treatment plant, a
water treatment plant, water distribution and sewer collectionrsystems. In order
to streamline operations and maximize efficiency, the City is currently involved
in the installation of a city-wide telemetry system. This will involve the process
of automating many items, areas and processes.
The method used to accomplish this goal will be the installation of the
telemetry system. Telemetry is a very simple means of remote metering.
Telemetric equipment includes the complete measuring, transmitting and receiving
apparatus for recording, or otherwise using the value of some quantity from a
remote location. In water utilities telemetric information is most often
transmitted over telephone lines. However, it is possible to transmit over
other means of communication, such as radio or microwave.
By installing telemetric receivers at some convenient central location, one
can supervise and monitor the operation of several remote stations and processes.
The utilities division budget year 1984-85 identified the need to control various
processes through the use of telemetry and funds were allocated.
City staff viewed various types of systems. Of these, staff selected the
Bristol telemetry system for installation at the wastewater treatment plant.
The Bristol equipment provided the city with all of the needed features and
was the most cost effective.
Staff recommends the city continue to single source the purchase of this
equipment for the rest of the telemetry system. This is consistant with
purchasing control procedure 201=1 for single source purchases.
To insure system wide compatibility a consultant was commissioned to
assemble a telemetry master plan. The master plan identifies control
philosophy, areas of control, types of equipment required to accomplish
the task for each of the defined areas, and a cost analysis. As outlined
in the telemetry master plan the water treatment plant, distribution system,
Whale Rock Reservoir, and the sewer collection system are all scheduled to
install Bristol telemetry.
The use of the telemetry system will provide operational personnel
with a mechanism to monitor the entire system from a central
location and to obtain information at a moments notice. It will also

allow personnel to turn pumps on/off at a central location, change
reservoir elevations, and to streamline pumping. efficiency. The
telemetry system will reduce the number of man hours spent
accomplishing these tasks at the present time.
PHASES
The project- has been divided into four (4) major phases. Phase one
consists of the identification and purchase of hardware needs for the
water treatment plant, sewer collection system, Whale Rock Reservoir,
and selected reservoirs within the water distribution system.
Due to the scope of the project and the numerous components required
for purchase and installation staff will return to you in the noted
time frames for approval of the following phases:
Phase two consists of authorization to proceed with the
communication link (8/88) .
Phase three consists of authorization to proceed with the
installation of the hardware portion (9/88) .
Phase four consists of the authorization to proceed with the
remainder of the water distribution system, hardware,
communication link and installation (2/89) .
ALTERNATIVES
1. Do not undertake the project.
Pros
1. Savings to the City of previously allocated funds:
Cons
1. Continuation of inefficient and ineffective system operation.
2. Continuation of archaic and labor-intensive system operations.
FISCAL IMPACT
The cost of Phase One is estimated to be $85,000. Funding for the
project will come from the following account numbers:
Account Number Appropriated Balance
052-9787-091-572 $ 65, 000 $ 51,271.39

There has been a total of $160,000. allocated towards the telemetry
system. Up to this point $39,555.61 has been spent towards the
purchase of the telemetry system.
The purchase of all components of the telemetry project will be in
accordance with purchasing control procedures 401-3 and 201-1. Even
though we are single sourcing the purchase of Bristol equipment,
there will be a competitive bid among the various representatives.
RECOMMENDATION
Approve the purchase of telemetry hardware for the water treatment
plant, a small portion of the water distribution system, Whale Rock
reservoir and the sewer collection system.
