Ventura Pierpont Neighborhood Stormwater Lift Stations

The City of Ventura’s Dover and Weymouth stormwater pipelines and pump stations were built in 1970 to mitigate flooding along the Pierpont Bay Neighborhood. In addition to stormwater runoff mitigation, the reinforced concrete pump stations also serve as public access points for the beach. The pump stations had reached the end of their service life and showed signs of deterioration. Cannon was selected to provide design services for the pump station upgrades, including three 4,100-gpm mix flow pumps and one 1,600-gpm submersible pump with a lift of 17 feet. We analyzed the pumping requirements and designed two identical stormwater pump stations, including structural upgrades; new electrical Southern California Edison service; and Americans with Disabilities Act access to the beach. The design included survey, civil, electrical, mechanical, structural, and SCADA. This project met the City’s goals to increase pump station efficiency  and provide structures and pumping plants able to weather the Pacific Ocean storm long into the future.
