This project replaces aging pumps and electrical equipment used to pump up to 20 million gallons of water daily from the Soulajule and Nicasio reservoirs to the San Geronimo Water Treatment Plant. It includes construction of a new fire-hardened electrical controls building designed to the highest seismic safety specifications to bolster water supply reliability, as well as replacement of five pumps and motors and critical valves.

Investing in your water system
Tocaloma Booster Pump Station was built in 1961 and is the primary means of conveying raw water from Nicasio Reservoir to San Geronimo Water Treatment Plant located in Woodacre. In service since the station was built, the existing electrical equipment is now obsolete, with limited repair parts available. In addition, the existing pumps aren’t nearly as efficient as modern versions. This project will allow the District to reliably and efficiently operate the station with water flow flexibility and reduce the PG&E electrical bill by lowering the start-up electrical charges.
