See where your water goes after it's poured down the drain!

Every drop of water used in and around homes and businesses in the RWQCP service area travels to San Francisco Bay. Sink, shower, and toilet water travels to the RWQCP for wastewater treatment where biological wastes are removed. Stormwater travels to creeks and the Bay without treatment, so remember to only let rain down the stormdrain. Check out our infographic to see the map of where your water travels after its used.

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.

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.

NEW 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.
