WHAT IS THE REGIONAL WATER QUALITY CONTROL PLANT?

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

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.

SMOKING ORDINANCE CHANGE

The City of Palo Alto recently took additional steps to protect public health and reduce litter by expanding the City's Smoking Ordinance. The revised ordinance prohibits smoking in multi-family housing (inside, common areas and buffer areas or sidewalks) and places restrictions on the sale of tobacco products. Smoking restrictions remain for outdoor commercial areas, outdoor dining areas, public events, work sites and service locations.

POLYSTYRENE ORDINANCE

On March 1, 2016 revisions to a 2009 City of Palo Alto ordinance went into effect to further reduce litter from expanded plastic foam products (e.g., Styrofoam™). The ordinance prohibits both the retail sale and distribution of plastic foam ice chests, egg cartons, packaging materials and foodware. This measure is one of several to reduce litter in creeks, streets, and the Bay. Learn more.
