Prepare Water Master Plan (Project No. 600144):
During Phase I and II of the project, additional information on the City system has been developed
regarding the existing City wells and reservoirs. Some of the wells have structural defects and have
reached their limit of useful life while an additional study of the structural integrity of reservoirs has
resulted in a re-priodtization of the repair costs and schedule.
The master plan will combine and update the results of the new information with existing studies into one
report which will recommend the necessary improvements to maintain the water system for the next 20
years. The plan will address life expectancy of wells, storage upgrades, proposed improvements to the
distribution system and a CIP update.
The existing City computer model will be revised and a state-of-the-art computer model will be developed
to analyze the hydraulics, of the City system. This model will be used to:
Determine which portions of the backbone pipeline system will require upgrading to use
high capacity wells.
Model water demand and. supply conditions so that the City can maximize use of lower
cost local groundwater.
Analyze the system to determine water quality parameters throughout the entire
distribution system. This model will be beneficial in allowing City operations staffto meet
changing water quality requirements.
Subtotal $37.500
TOTAL Phase III
$655,000
BACKGROUND
Discussion
In 1992, the City Council reviewed and approved a funding plan to support a twelve year development
program to construct the recommended water system improvements. Although significant progress had
been made as of 1995, the total program was approximately two years behind schedule. In an effort to
expedite the program, ASL Consulting Engineers was retained through a competitive proposal process
to provide program management services for the City. These services include preparation of requests for
proposals, selection of consultants, negotiation of contracts, management of consultants, plan checking,
coordination, preparation of CEQA documents, meetings and reports. The program management contract
was structured in five phases, with each phase requiring separate approval by City Council.

Significant progress has been made during Phases I and II. The following is a list of these
accomplishments.
Phase I
A 7-year program along with a budget has been developed for completion of the CIP.
A preliminary plan for the Main Street site has been completed.
Appraisals have been completed and land acquisition for two parcels required to construct
the Main Street site. One property is in escrow and an offer for the other property is being
developed.
A preliminary site plan for the Rawlings Zone II Booster Pump Station was completed.
A detailed structural analysis of the Foothill, Simon Ranch and Rawlings Reservoirs has
been completed. This analysis indicated that minor repairs are required at Foothill
Reservoir while major structural repairs are required at Simon Ranch Reservoir. In
addition, it was determined that due to major structural inadequacies, the Rawlings
Reservoir should be demolished and a new, larger reservoir constructed at the site.
A preliminary site plan for Simon Ranch Booster Pump Station was completed.
Five water main replacement projects were designed and constructed involving 17,179 feet
of water main at a cost of $1,003,715.
The remaining item in Phase I is the.final acquisition of the two parcels required to construct the Main
Street site.
Phase II
The following items have been completed:
A design consultant has been selected for Main Street project (Black & Veatch).
CEQA documents and a preliminary design report have been completed for Main Street
site.
A design consultant has been selected for Main Street Well No. 4.
Demolition plans for Main Street site have been completed.
Plans and specifications for drilling of Well No. 4 have been completed.
An agreement with OCWD for funding assistance for Well No. 4 have been completed.
A design consultant for Rawlings Zone II Pump Station (Daniel Boyle Engineering) has
been selected.
A preliminary design report for Rawlings Zone II Pump Station has been completed.
Final plans and specifications for the Rawlings Zone II Pump Station have been completed
to the 90% stage.

A design consultant for Simon Ranch Pump Station (AKM Consulting Engineers) has been
selected.
Preliminary design report for Simon Ranch Pump Station has been completed.
Design consultants for 13,766 feet of water main improvement projects has been selected
(SA Associates and Daniel Boyle Engineers).
Design of 13,766 feet of water main replacements has been completed.
Consultant selection for chlorination and electrical upgrades to existing wells has been
completed (MacDonald Stephens Engineers).
Analysis of useful life of existing City wells has been completed.
A preliminary design report for chlorination and electrical upgrades has been completed.
The remaining work under Phase II includes:
Completion of final plans and specifications for Main Street Reservoir (currently at 90%
complete).
Completion of final plans and specifications for Rawlings Zone II Pump Station (currently
at 90% complete).
Completion of final plans and specifications for Simon Ranch Pump Station (currently at
35%)
Completion of final design of chlorination and electrical upgrades to existing wells
(currently at 50% complete).
The majority of ASL's efforts during Phase IH will be to provide construction management services and
construction observation for the following projects:
Main Street Well No. 4
Main Street Demolition
Main Street Reservoir
Rawlings Pump Station
Simon Ranch Pump Station
Electrical and Chlorine Upgrades
These construction projects are planned to start in May and be completed in approximately 15-18 months.
The total construction costs are estimated to be approximately $9 million.
In addition to these construction management services, ASL will also provide program management
services for the Foothill Reservoir and the Pasadena Avenue Well and design water main replacement
projects on 17' Street and Prospect Avenue. Phase III of the contract is the largest phase due to the
amount of construction involved. During this phase up to five different contractors will be working
simultaneously.

An additional task to prepare a comprehensive water master plan for the City was budgeted in the FY97-
98 Capital Improvement Program and has been added to Phase Ill of the contract.. The results of studies
performed during Phases I and II revealed that some of the City's existing wells are approaching the end
of their useful life. New, larger capacity replacement wells may require backbone pipeline distribution
system to be modified due to a change in the system from numerous small wells to fewer high capacity
wells. The master plan will update the existing water system hydraulic model and will evaluate the City's
ability to provide groundwater to serve the system. A comprehensive plan to use the lower cost
groundwater in lieu of the more expensive purchased water will be developed. In addition, the City's
required storage, emergency power and CIP will be evaluated, updated and documented.
To date ASL Consulting Engineers has provided substantial assistance to the City staff. Specialized
expertise and additional manpower provided by ASL has helped to keep the overall CIP program moving
towards completion. Attached is a schedule indicating which projects will be completed as part of Phase
III. Timely completion of the Main Street Reservoir, Well No. 4 and Rawlings Pump Station will result
in significant savings in the future by reducing the amount of high cost imported water which the City
purchases.
The consultant contract terms will remain the same and the consultant has agreed to hold hourly rates at
the 1995 level. In addition, the contract will continue to be paid only upon completion of milestones. The
staff.to date has been very pleased with the performance of ASL and recommends that the City continue
the contract by adding Phase III.
