Modernizing Today for Tomorrow’s Wastewater Challenges

Learn about the CIP

As a vital business and residential center, Silicon Valley requires a modern, state-of-the-art treatment plant to reliably clean its wastewater. The Facility is addressing this need through its Capital Improvement Program (CIP), rebuilding infrastructure worn from over 60 years of nonstop service, and updating treatment processes with exciting new technologies.

The CIP plans and carries out selected projects recommended by the 2013 Plant Master Plan, which envisions $2 billion in Facility investments over the next 30 years. Key CIP elements include:

  • Infrastructure rehabilitation at all stages of the treatment process for greater efficiency and reliability.
  • New, more efficient biosolids (sludge) dewatering and drying processes to better control odors and reduce the operational footprint.
  • New methods of generating energy to sustainably power Facility operations.
