Through Phase One of the SSIP, our planned improvements will upgrade our critical aging and seismically vulnerable grey infrastructure like pump stations and treatment facilities into a state of good repair.


SEP building with large pipes

Southeast Treatment Plant

The SSIP will upgrade components of the Southeast Treatment Plant. As one of the first projects, the SFPUC will build a new biosolids digester facility to replace the aging system.

OSP Digesters with Stairs

Oceanside Treatment Plant

The SSIP will improve treatment performance, prevent corrosion and increase seismic reliability of the Oceanside Treatment Plant and associated facilities which treat 20% of the City's flows.

NPF Front of the Facility

Northpoint Wet Weather Facility

The SSIP will address major improvements to the North Point Facility, Northshore Pump Station, and associated outfalls to ensure the NPF continues to serve San Franciscans wastewater needs.

CBSIP pipes

Central Bayside System Improvement Project

The first phase of SSIP will look into improving the capacity, conveyance and reliability of the collection system on the Bayside of the City.
