San José-Santa Clara Regional Wastewater Facility

The San José-Santa Clara Regional Wastewater Facility is the largest advanced wastewater treatment facility in the western United States. It works 24/7 to clean Silicon Valley’s wastewater to very high national standards, protecting public health and environment and supporting the economy.

Using a treatment process that simulates the way nature cleans water, the Facility treats an average of 110 million gallons of wastewater per day (mgd), with a capacity of up to 167 mgd.

The Facility serves 1.4 million residents and over 17,000 businesses in eight cities and four sanitation districts:

  • Cities of San José, Santa Clara, Milpitas
  • Cupertino Sanitary District (Cupertino), West Valley Sanitation District (Campbell, Los Gatos, Monte Sereno, and Saratoga)
  • County Sanitation Districts 2-3 and Burbank Sanitary District (both unincorporated)

The Facility is jointly owned by the cities of San José and Santa Clara, and is managed and operated by the City of San José’s Environmental Services Department. The city councils of San José and Santa Clara, the Treatment Plant Advisory Committee (TPAC), and the Technical Advisory Committee (TAC) oversee the Facility’s activities.

Our future
A leader in wastewater innovation, the Facility is integrating cutting edge treatment technologies into its processes and rebuilding aging infrastructure through its $1.4 billion, 10-year Capital Improvement Program. This modernization will ensure a sustainable future for the Facility and the vital services it provides.
