DISCUSSION:
On June 26, 2001, the City Council authorized the award of the Zone III and IV Pump
Station Electrical Improvements contract to Rich Construction. The contract provided
for the installation of the pumps, motors, and electrical controls to run both the Zone III
and IV pump stations. The Zone III pump station was also equipped with variable
frequency drives to provide a more energy efficient system for this pressure zone,
which serves one -third of the City. In addition, a backup generator was installed to
provide emergency power to the Zone III pump station. The Zone IV pump station was
already equipped with a diesel driven backup pump in case of a power failure.
By replacing the pumps and motors and utilizing the new variable frequency drives in
the Zone III controls, energy costs can be reduced by twenty -five percent. This equates
to a yearly cost savings of approximately $55,000.00.
The project completion was delayed because of operational constraints on the City's
water system. Final testing and certification of the station was approved and the
contract has now been completed to the satisfaction of the Public Works and Utilities
Departments. A summary of the contract cost is as follows:

Environmental Review:
The project was determined to be exempt from the California Environmental Quality Act
(CEQA) pursuant to Section 15302 of the CEQA Implementing Guidelines at the time
the project was authorized by the City Council. This exemption covers the maintenance
and alteration of existing public facilities with negligible expansion of the facilities in
areas that are not environmentally sensitive.
