The Regional Water Quality Control Plant (RWQCP) protects San Francisco Bay by treating wastewater from its service area and works with residents, industry and businesses to prevent pollution before it starts. The RWQCP is owned and operated by the City of Palo Alto and serves its partner communities of the East Palo Alto Sanitary District, Los Altos, Los Altos Hills, Mountain View, Palo Alto, and Stanford University.
Stormwater is runoff generated when precipitation flows over land or impervious surfaces (streets, parking lots, building rooftops, etc.) without infiltrating into the ground.
This runoff picks up pollutants as it flows into storm drains, leading directly into creeks and the San Francisco Bay. Storm drain systems are separate from sanitary sewers and flow into our watershed without any treatment. During heavy rainfall, excess runoff causes flooding to occur.
