The Value of Recycling

The primary mission of the Sunnyvale Water Pollution Control Plant is to conduct a cost-effective wastewater management program that is environmentally sound and regulated to protect public health, safety, property, and the quality of the Bay. But while consistently meeting this goal, the Plant becomes a significant water and energy conservation generator. It reuses many byproducts of the treatment process. These include producing electricity and mechanical power from waste gases, recovering heat from engines, producing an alternative to soil for daily landfill cover or a soil amendment for agricultural and pasture land, and supplementing the city water supply by producing recycled water distributed through a separate system for non-potable uses.

For Sunnyvale water customers, recycled water is produced by diverting a portion of the flow and providing additional treatment. This additionally treated water meets all non-potable Title 22 standards established by the State. It is distributed through a separate underground piping system to provide irrigation for industrial parks, the Sunnyvale Municipal Golf Course, Baylands Park, and sports complexes. In 2018, the plant produced a total of 263 million gallons (MG) for recycling.

These efforts will augment the City’s existing water conservation programs.
