San Rafael, CA – June 30, 2017 – The Ross Valley Sanitary District (RVSD) Board of Directors approved the award of a $6,998,000 construction contract to fully rehabilitate two existing wastewater pump stations. Pump Station 12 (PS 12) and Pump Station (PS 13) are located adjacent to the Bon Air retail complex in Larkspur, along Sir Francis Drake Blvd.

“Pump Stations 12 and 13 were constructed way back in 1983, and have not been significantly upgraded in 30-plus years,” said Board President Mary Sylla. “We prioritized their rehabilitation in our 2013 Infrastructure Assets Management Plan because functional pump stations are the cornerstone of a functional sewer system, one that keeps sewage in the pipes.”   

The pump stations are part of a network of five pump stations used to convey between four million gallons per day (MGD) of dry weather flows and up to 60 MGD of wet weather flows to the Central Marin Wastewater Treatment Plant in San Rafael. Both pump stations will undergo comprehensive upgrades including new pumps, motors, piping, valves, odor control systems, electrical systems and backup power generators.  

As Greg Norby, P.E., General Manager of RVSD explained, “The upgrades will improve the energy efficiency of the pump stations, enhance service reliability under peak wet weather flow conditions and integrate the two stations into the CMSA regional SCADA system for improved real time monitoring.”

The construction contract was awarded to Santa Clara based Anderson Pacific Engineering and Construction.  Construction management is being provided by Covello Group of Walnut Creek. Engineering design was completed by Water Works Engineering of Redding, CA.  Construction will commence in July of 2017 and is expected to take approximately 18 months.
