Wastewater

The Wastewater Division of the Public Works Department is responsible for the wastewater collection system throughout the City including all sewer mains, manholes, lower laterals, and 7 lift stations. Wastewater treatment is handled under a Joint Powers Agreement with the City of South San Francisco. Approximately 3.4 million gallons of effluent per day are pumped from San Bruno through the Shaw Road Pump Station to be treated at the South San Francisco/San Bruno Water Quality Control Plant.

The treatment plant, which is located on Belle Air Road in the City of South San Francisco, just north of the San Francisco International Airport, is operated and maintained by the City of South San Francisco. Treated wastewater is discharged two miles out into San Francisco Bay via a join outfall pipe shared by the San Francisco Airport and the cities of:

• San Bruno
• South San Francisco
