The mission of the Regional Water Quality Control Plant (RWQCP) is to protect San Francisco Bay by cleaning and treating wastewater before it is discharged to San Francisco Bay.

Owned and operated by the City of Palo Alto, the Plant treats wastewater for the communities of Los Altos, Los Altos Hills, Mountain View, Palo Alto, Stanford University and the East Palo Alto Sanitary District.

Biosolids Facility Plan

The RWQCP is planning and designing a new biosolids facility.


The RWQCP is pursuing the construction of an additional outfall pipe to convey effluent (cleaned and treated wastewater) to San Francisco Bay. The new pipe would run adjacent to the existing outfall pipe which releases effluent near the Palo Alto Airport.

Construction efforts would also include maintenance for the existing 52-year old outfall pipe, and pump replacement for effluent discharged to nearby Renzel Marsh adjacent to East Bayshore Road. Together, these projects would ensure reliable transport of treated effluent under projected climate change and sea level rise scenarios. Both projects are recommendations of the Long Range Facilities Plan (LRFP), completed in October 2012 and accepted by Council in July 2012 (Staff Report ID 2914).

A public meeting to discuss this project has been scheduled for Wednesday, January 17, 2018, 5-6:30pm. The meeting will be held at Cubberley Community Center, Room D1.
