SCOPE O~' SEItVICES
2010 ~TRBAN WA'TER IVIANAGEIVIEN~' PI,AN
~ACKGItOiJNI)
The Department of Water Resources and Conservation provides comprehensive and integrated
management of Petaluma's water resources. Delivery of a high quality, reliable supply of water,
and collection and treatment of wastewater are conducted 24 hours a day, 365 days a year for
approximately 19,400 utility customers.
Approximately 90% of the City's water supply is currently provided through water purchased
from the Sonoma County Water Agency, with approximately 10% provided by local
groundwater. Potable water is distributed to the City's customers through nine (9) pump
stations, eleven (11) storage tanks/reservoirs, five (5) pressure zones, and over 270 miles of
pipeline. After the water is used and discharged by the City's customers, it is collected through
an underground network of over 190 miles of collection system pipeline. A system of nine
collection system pump stations pumps the wastewater to the City's wastewater treatment
facility. After receiving secondary treatment at the City's Ellis Creek Water Recycling Facility
(WRF), the wastewater is released to the Petaluma River during the winter, and recycled during
the summer for irrigation of approximately 500 acres of agricultural land, turf (two golf courses)
and one vineyard. The City is expanding its recycled water program to include urban irrigation
with tertiary recycled water produced by the Ellis Creek WRF. The EIR supporting this program
was adopted in November 2008. The primary purpose of this program is to offset the use of
potable water for irrigation of landscapes that can be irrigated with recycled water. This program
will help the City meet future water demands, preserve potable water for its highest and best use
and reduce operating expenses. The City is prohibited by regulations from releasing treated
effluent into the Petaluma River from May 1 through October 20`~. The Ellis Creek WRF has an
average dry weather flow (ADWF) capacity of 6.7 mgd. ADWF in 2008 was 4.19 mgd.
The City provides wastewater service to appmximately 17,000 residential customers in Petaluma
and a~pproximately 400 equivalent single family dwelling units in the unincorporated Sonoma
County community of Penngrove under a Joint Powers Agreement with the Sonoma County
Water Agency.
As shown in Table 1, annual water demands peaked in Water Year 2001 (November 2000 -
October 2001) and have decreased since then. Total annual water demands in Water Year 2009
were at their lawest levels since Water Year 1992. Reduced water demands have resulted from
tiered water rates, increased conservation and use of recycled water.

One of the key considerations in the preparation of the 2010 UWMP is the change in water
dernands. The 2005 UWMP anticipated water demands would increase after 2005. As
illustrated in Table 1, water demands have been decreasing since 2001.

understanding of the requirements of the Urban Water Management Planning Act, and the City's
water ,and recycled water utilities. Consultant shall prepare a list of information needed from the
City far review. The list shall include, but not be limited to:
a City of Petaluma General Plan

Consultant.
o Sonoma County Water Agency 2005 Urban Water Management Plan
~ Restructured Agreement for Water Supply
~ Guidebook to Assist Water Suppliers in the Preparation of the 2005 Urban Water
Management Plan (if update is completed, review 2010 guidebook).

To gain familiarity and understanding about the utility, Consultant shall conduct site visits to the
City's water and recycled water systems, including the Ellis Creek Water Recycling Facility.
Consultant shall undertake other actions as needed to become familiar with the water and
recycled water utilities and understand their operations.
'Task 3 - Deterieiine Water Demand
The City of Petaluma 2005 Urban Water Management Plan was based on the Water Demand and
Supply Analysis Report (Report) which is included in the City of Petaluma General Plan. The
Report used 2002 as the base year for projecting future water demands. Water demands were
calculated based on the City's adopted land use plan, and planned growth through 2025. Since
then, water demands have decreased. The purpose of this task is to calculate future water
demands. This information will then form the basis for the City of Petaluma 2010 Urban Water
Management Plan.
o Make recommendation for base year.
• Identify historical and existing water use characteristics and demands.
~ Determine water demand based on General Plan 2025. Break down demands into
specified 5-year implementation periods or other appropriate period.
~ Determine and/or confirm water use factors for current and future land use categories.
Verify that water use factors are reasonable through comparison to published data and
data from other nearby agencies.
Resolution No. 2010-121 N.C.S. Page 4
• Evaluate impact of new construction standards, tier 2 conservation measures, and
legislative conservation requirements, including SB X7-7 Water Conservation
Requirements, SB 407 Plumbing Retrofit on Resale/Remodel, and AB 1420 Demand
Management Measures.
• Determine water demands through build-out of the General Plan by: 1) Using a land use
and planned growth methodology similar to what was used in the WDSA report, and 2)
By using the Demand Side Management Least Cost Planning Decision Support System
(DSS model), or alternate model acceptable to the City.
Task 4- Review Water Supplv to Meet Proiected Demands
~ Review background information on SCWA supply, groundwater, recycled water, and
water conservation.
• Review SCWA's Biological Opinion and other documents related to SCWA's water
supply.
. Assume recycled water will be delivered to customers in the quantity and form as
described in the General Plan 2025, but not necessarily as scheduled. Reduced water
usage has allowed the City to push back the schedule for completing the recycled water
projects. Re-evaluate schedule and determine when projects should be implemented
based on updated water projections and other water supply sources.
s Water conservation.
o Ensure analysis reflects data in Water Conservation Plan (2008).
o Update water conservation model to incorporate changes City has implemented
since the Water Conservation Plan was adopted, City's actual water conservation
performance, and legislative code changes.
• Review grouridwater plan included in General Plan 2025.
Task 5- Develop Assumntions and Evaluation Criteria
Develop assumptions and evaluation criteria to analyze the alternatives to be developed in Task 6
to determine the recommended water supply plan to meet the City's water demands through
buildout of the General Plan 2025.
'Tas~ 6 - IDeveloq and .Evaluated Alternatives
~ Identify up to four alternatives to be evaluated using the Water Demand and Supply
Analysis report as a basis. Analyze alternatives based on:
o Cost
o Feasibility
o Advantages/disadvantages
~ Develop alternatives in sufFicient detail to allow side-by-side comparison.
o Identify least cost alternative.
m Recommend alternative for implementation.
Taslk 7- Prepare Water Suaplv Report
Resolution No. 2010-121 N.C.S. Page 5
• Consolidate all previous tasks into a single usable dacument that outlines the
methodology used to determine the recommended approach for water supply and offset to
meet Petaluma's water demands through 2025.

~ Attend two (2) meetings to review report with City and City's comments.
o Incorporate City's comments into a final report.
~ Provide five (5) copies of final report to City.
• Provide electronic copy (PDF and MS Word) of report to City.
