SUBJECT: WATER REUSE PROJECT - PROCEED TO PHASE II OF DESIGN
CAO RECOMMENDATION
Authorize the Utilities Director to direct Brown & Caldwell to proceed to phase II of the design
of the Water Reuse Project.
DISCUSSION
On December 2, 1997 the City Council approved a contract with Brown and Caldwell for the
design of the Water Reuse Project. The design is to proceed in three phases. Completion of the
fust design phase and dismissal of all protests to the City's Petition for Change of Point of
Discharge, Place of Use, and Purpose of Use of Treated Wastewater make it appropriate to begin
the second phase of the design.
In phase I.customer information has been verified, modifications needed for the Water Reclamation
Facility to meet State Department of Health Services (DOHS)water quality requirements have been
identified, the condition of the abandoned oil line in Pismo Street has been investigated,
modifications required for City sites to use recycled water have been identified, and the Engineering
Report has been prepared for submission to DOHS and the Regional Water Quality Control Board
(RWQCB). The Engineering Report defines the operation of the treatment plant, the places where
the recycled water will be used, and the procedures that the City will follow to assure that the use of
recycled water complies with State regulations. A copy of the Draft Engineering Report is available
in the Council office for review.
Phase II will evaluate: alternative pipeline alignments, storage options, sizing of the delivery
system,the potential for phasing construction, alternative rate structures,construction and operation
cost estimates; and design alternatives. Initiation of phase II was to be delayed until the completion
of the State Water Resource Control Board (SWRCB) hearing on the protests to the City's petition
for change. Council asked that staff return at that time to obtain a verbal approval to begin this
phase. Since all the protests have been dismissed and the petition is being processed
administratively, staff is confident that the petition will be approved for the project as defined in the
EIR with a minimum release of 1.7 cfs.
Phase III will include surveying and aerial mapping of the pipeline routes, geotechnical
investigation, and the preparation of plans and specifications for the construction of the Water
Reuse Project. Phase III will not begin until the City Council approves a design report presented at
the conclusion of phase II.

Council Agenda Report—Water Reuse Project- Proceed to Phase II of Design
Page 2
Starting phase II of design at this time will provide a preliminary design report for discussion of
alternatives with Council in April. At that time staff anticipates that the mitigation measures will
be defined sufficiently that the project scope and mitigation measures can be reviewed and
approved by Council.
The Agreement for Design of Water Reuse Project Distribution System specifies compensation for
each phase to be:
Phase I $98,828
Phase II $65,680
Phase III $567,449
Special Services $50,000
Contract TOTAL 781,957
Work on each phase must be completed and the Utilities Director must give written approval before
work is started on the next phase. Council must approve the scope of the project to move from
phase II to phase M. Council also asked that the project be brought back for a verbal approval to
begin IL The critical issue was the amount of water that would be available for the project. Since
all of the protests have been withdrawn and the resource agencies are supporting the project with a
minimum discharge of 1.7 cfs,the project will produce 1,233 acre-feet for irrigation and other uses
as described in the EIR.
Project Schedule
Phase I began when the contract was approved in December of 1997. Phase II is expected to take
four months, and phase III is expected to take 8 months. Bidding, award, construction, and startup
are expected to take 18 months. This schedule provides for recycled water to be used during the
summer of 2002.
FISCAL IMPACT
This action will authorize the consultant to proceed with phase II of the design of the Water
Reuse Project. The Council has previously appropriated the money and approved the contract for
this work. This phase of the design will cost $65,680.
Attachment
The Draft Engineering Report is available in the Council Office.
