Canal West Pump Station Upgrades
City of Antioch | Antioch, CA

Situation: Known for its beautiful landscape and large homes, the City of Antioch is mainly viewed as a “bedroom” community because the majority of its residents work in surrounding cities, as far away as Oakland and San Francisco. Dozens of new neighborhoods within the City’s jurisdiction have been developed over the past 30 years pushing the existing infrastructure beyond its capacity. The City was focused upon infrastructure improvements including the upgrade of its water treatment plant to approximately 40 million gallons per day (MGD) of untreated water.

Special Challenges: Despite the upgrade, the water treatment plant’s existing raw supply pumps were insufficient and thus inefficient. The City retained Pakpour Consulting Group (PCG) to design pump upgrades in order to meet full capacity and improve overall efficiency. PCG also provided design services for the construction of a new building to house the electrical equipment as well as the installation of a permanent 450 kW emergency generator, an automatic transfer switch, and SCADA upgrades. With the system upgrades, the City now has the ability to operate a 300-hp pump along with one 125-hp pump and its generator to maintain operations in the event of an emergency.

Services Overview: In conjunction with its electrical and mechanical subconsultant, YEI Engineers, PCG provided full design and construction support services for the electrical upgrades and replacement of the existing 200-hp pump with a more efficient 300-hp pump. This upgrade allowed for the concurrent operation of the pumps. PCG has provided various engineering and construction support services to the City since 2010.

About City of Antioch: Founded in 1850, Antioch is among the oldest cities in California. Located in the East Bay Region of the San Francisco Bay Area, the City is situated along the San Joaquin-Sacramento River Delta in Eastern Contra Costa County with a population of approximately 109,000.
