About the Plant
The Donald M. Somers Water Pollution Control Plant is an advanced wastewater treatment facility serving residents, businesses and industries in the city of Sunnyvale.
Wastewater draining from indoor sources in Sunnyvale flows through sewer pipes that direct the wastewater to the Water Pollution Control Plant for treatment before being discharged to the San Francisco Bay. If left untreated before discharge, residential, commercial and industrial wastewater would upset the delicate ecosystem of southern San Francisco Bay.
In addition to wastewater treatment, services include regulatory permitting and inspections of pretreatment facilities and storm water management for business and industry in Sunnyvale, information on water pollution prevention and environmental education services to schools and youth.
Funded by user fees, the mission of the 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.
Originally constructed in 1956, the plant utilizes primary, secondary and tertiary treatment processes to treat the wastewater. Click on one of the following links for additional information on the Water Pollution Control Plant.

Wastewater Treatment Reuse
The City of Sunnyvale is within the Santa Clara Basin Watershed, which drains rainfall and other water runoff through creeks and rivers to the South San Francisco Bay. Sunnyvale and the other agencies in this watershed that have responsibility for water quality are pursuing a regional or "watershed approach" to addressing issues. This means bringing all interested stakeholders together to discuss problems within the natural geographic framework in which they occur (a watershed). It is hoped that by working cooperatively, the most effective and efficient solutions can be developed.
For a description of two of these regional, watershed-wide efforts, the following links are provided.
