Rebuilding for Operational Reliability, Sustainability and Regulations

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, designs, and constructs projects recommended by the 2013 
Plant Master Plan, which envisions $2 billion in Facility investments over a 30-yearspan. The first phase is a 10-year CIP with $1.4 billion of improvements, which started in July 2014.

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. 

The first phase is a 10-year CIP with a budget of 1.4 billion, which started in July 2014.
