Seacliff 1 & Seacliff 2 Pump Stations and Force Main Upgrades

What's a Pump Station and Force Main?

Our combined sewer system is mostly gravity operated, but in some parts of the City, pump stations are necessary to pump combined wastewater flows to treatment facilities. To convey the flows from the pump stations, force mains are the pressurized pipes that help move flows from the pump station and through the system. 

Project Benefits:

• Maintain critical sewer system services by upgrading both Seacliff 1 and Seacliff 2 Pump Stations and Force Mains
• Meet seismic standards
• Increase sewer system reliability
• Protect water quality and aquatic life in the Bay

Seacliff 1 Pump Station & Force Main Upgrade:

This pump station and force main are operating beyond their service life and are located in an area that is difficult to access for repairs or upgrades. To continue serving this neighborhood, a new pump station is proposed to be constructed in a more accessible location and within the public right-of-way. The proposed pump station will be constructed to meet the current level of service requirements; thereby, providing additional protection from system overflows during heavy storms. The project also proposes to replace nearly 1,000 linear feet of force main that serves the pump station.

• Anticipated Construction Schedule: Construction is anticipated to begin in 2025, with an estimated duration of 1 year.

Seacliff 2 Pump Station & Force Main Upgrade: 

This pump station and force main are operating beyond their service life, and a more comprehensive upgrade is now being undertaken. This project will rehabilitate the existing pump station, replace most of the mechanical & electrical equipment; retrofit the underground structures; and provide architectural and safety upgrades. The project will also replace and upsize the existing 80-year-old force main.

• Anticipated Construction Schedule: Construction is anticipated to begin in 2025, with an estimated duration of 2 years.
