Sewers in our County

Operated under Santa Clara County, our waste water is transported from our buildings through sewer mains by way of pumping stations to a treatment facility at the San Jose-Santa Clara Water Pollution Control Plant (WPCP). The WPCP has the capacity to treat 167 million gallons each day, and is also utilized by other cities in Santa Clara County.The wastewater is then treated in three stages: primary treatment, activated sludge secondary treatment, and advanced tertiary treatment. The fresh water is then discharged to the South San Francisco Bay or delivered to the South Bay Water Recycling Project.
