WCW protects our local waters, including the San Pablo/San Francisco Bay, and saves valuable drinking water by treating wastewater for clean, safe release or reuse. We rigorously test our treated water, ensuring viruses, bacteria, and other contaminants do not survive. Nearly all of our discharged water is used as recycled water in industrial cooling towers and boilers, keeping more potable water available for drinking and lessening the amount released into the Bay. This also saves energy by reducing the amount of electricity used to pump water to the Bay.
In addition, we test for contaminants at the source, working with local commercial customers to prevent pollution before it enters the wastewater system. Our team also responds to sewage and overflows around the clock. Without immediate attention, overflows often end up in rivers, lakes, streams, creeks, and oceans, and can lead to beach closures.
Our Water Quality and Resource Recovery Plant has repeatedly received the National Association of Clean Water Agencies Peak Performance Award, demonstrating 21 years of complete and consistent National Pollutant Discharge Elimination System permit compliance.
