SUBJECT: Resolution Accepting Completion of the Recycled Water Pump Station Upgrades
Project
It is recommended that the City Council adopt the attached resolution accepting completion of
the Recycled Water Pump Station Upgrades Project.
BACKGROUND
The City of Petaluma's recycled water system was constructed in 1981 and modified in 2009
with the completion of the Ellis Creek Water Recycling Facility (ECWRF) to continue recycling
secondary treated wastewater on golf courses and agricultural properties. During the dry -weather
season from May 1 to October 31, the City is restricted from discharging into the Petaluma River
and must recycle. The system had consisted of four pump stations and 12 miles of pipelines
which delivered water to over 1,000 acres of land. The system conveyed secondary treated
wastewater from the oxidation ponds at Lakeville Highway to irrigate of vineyards, golf courses
and agricultural lands.
In 2013, staff installed a temporary connection to allow the ECWRF tertiary filters to provide
treated waste water to recycled water users and to retire two of the old secondary effluent pump
stations adjacent to the aerated ponds. Previously, tertiary water was only used at the ECWRF as
"number 3" water for plant processing and site irrigation. The project has assisted in the
expansion of recycled water use within Petaluma City limits including an increase in the amount
of "potable water offset" credits for uses on City parks, schools and open space while improving
delivery reliability. The subject project included operational controls to better regulate flows and
pressures in the recycled water distribution system, replacing the temporary connection with a
full sized permanent connection, and added a small pump and meter to the tertiary water pump
station. The project location is shown on Attachment 2.

and Rooster Run turnouts; and additional improvements to the Tertiary Recycled Water Pump
Station, Urban Recycled Water Pipeline, Booster Pump Station 92 on Browns Lane, and turnouts
to agricultural customers.
