Ross Valley Sanitary District Completes Upgrades to Pump Stations at Bon Air and Greenbrae

San Rafael, CA  June 12, 2019 – Ross Valley Sanitary District (RVSD) held a community ribbon cutting on June 11 to mark the recent completion of upgrades made at Bon Air Pump Station 12 and Greenbrae Pump Station 13, both located in the Bon Air Shopping Center. The celebration at Pump Station 12 took place between Patxi’s Pizza and the Chevron Station.

“The District would like to thank community members, and especially the Bon Air Shopping Center community, for their patience while construction took place at both pump stations,” said General Manager Steve Moore. “This celebration is an opportunity to come learn about the innovative technologies and approaches being used for odor and noise control, as well as the historical significance of this important community asset.”

The system infrastructure at both Pump Stations 12 and 13 has been upgraded and/or replaced to enhance local wastewater system reliability and efficiency and to improve system performance during wet weather. These ratepayer-funded projects are needed to protect public health and the environment by reducing the risk of sewer overflows.

Project benefits at Pump Station 12 include increased capacity and reliability to move wet weather wastewater inflows of about 2 million gallons per day (mgd). The larger Pump Station 13 was upgraded to convey up to 13 mgd in wet weather. Dry weather flows at Pump Station 12 and 13 are about 0.2 mgd and 0.4 mgd, respectively. Upgrades to both pump stations include added bypass pumping capacity and related improvements that allow for planned station bypass during maintenance as well as for emergency operations if necessary, new and upgraded piping, valves, and new electrical and control systems. Both pump stations have diesel emergency standby generators with on-site fuel storage.

Pump stations collect, pump and transport millions of gallons of wastewater per day. RVSD operates and maintains 19 pump stations that transport wastewater from our homes and businesses to the Central Marin Sanitation Agency treatment plant—via a system of approximately 200 miles of collection sewer lines all over our Marin County region.

Ventilation systems at both pump stations have been replaced and improved to meet the requirements of NFPA 820 Standard for Fire Protection in Wastewater Treatment and Conveyance Facilities. Both pump stations also have improved odor control systems that scrub the air being ventilated to prevent odor migration off-site.
