Renovating One of the Oldest Wastewater Treatment Plants on the West Coast

Built in 1956, the City of Sunnyvale’s Water Pollution Control Plant is considered one of the oldest treatment plants on the West Coast and needs renovation. The City‘s first step in renovation is building a new Primary Treatment Facility. The magnitude of this construction required extensive site and sequencing preparation to maintain treatment during construction, bring the new system online, and then subsequently demolish outdated facilities.

Psomas provided pre-construction services, extensive constructability reviews, and bid-phase management during the preparation stage. Construction management and inspection services are being provided during the construction phase.

The three-step (tertiary) treatment facility removes pollutants from wastewater to make it clean enough to safely discharge into San Francisco Bay or recycle for non-potable uses such as landscape irrigation. In addition to producing about 300 million gallons of recycled water, the treatment process will yield more than 2,500 dry tons of nutrient-rich biosolids, that will be used for agriculture annually.
