Sunol Valley WTP Ozonation Design Milestone

SAN FRANCISCO—CDM Smith has completed the design phase on the Sunol Valley Water Treatment Plant (SVWTP) Ozonation project. The design received an Envision Silver Award from the Institute for Sustainable Infrastructure (ISI), reflecting its exemplary progress toward sustainability. These milestones mark the project team’s significant progress and support for the San Francisco Public Utilities Commission (SFPUC).

The goal of the project is to install ozone treatment facilities at the 168 million-gallons-per-day (mgd) SVWTP, a long-term water treatment solution to mitigate taste and odor events encountered in the raw water supply. The existing plant has a unique design, and implementing ozonation into the existing process, mechanical and electrical systems posed design and construction challenges for the team. The design utilizes a small footprint on the existing site and provides flexibility to either blend or treat water sources separately. The construction phase will carry into 2028.
