Wastewater Plant

Every drop of water we use ends up in San Francisco Bay, and it’s the job of the Regional Water Quality Control Plant to make sure it’s treated to remove pollutants before it gets there.

The Regional Water Quality Control Plant is owned and operated by the City of Palo Alto for the communities of Los Altos, Los Altos Hills, Mountain View, Palo Alto, Stanford University and the East Palo Alto Sanitary District. The Plant is an advanced treatment facility that uses gravity settling, biological treatment with microorganisms and dual media filtration to remove unwanted organic materials and toxins from the approximately 22 million gallons a day of wastewater generated by the service area’s 220,000 residents. The Plant’s treated effluent meets all of the stringent requirements for discharge to the sensitive South San Francisco Bay.

To contact the Watershed Protection Group and for questions regarding grease traps and restaurants, discharging wastewater, medicine disposal and our schools program call 650.329.2122.
