As of winter 2015, the Harry Tracy Water Treatment Plant project is more than 95% complete and on schedule to finish major construction at the end of February.
Since work began in 2011, construction workers have logged more than 1.2 million hours on the job for this important infrastructure investment. In recent months, the Contractor has completed building five new filters and two new washwater tanks. Work continues on the new Treated Water Sampling Building and in several locations throughout the plant.
The new 11 million gallon Treated Water Reservoir (TWR) is the largest and most complex part of the Harry Tracy construction. The new TWR is expected to finish the final testing phase in February and begin serving wholesale customers in March 2015.
|The new Treated Water Reservoir was filled with water late in 2014.
||Filtration capacity is being expanded at the plant.
This project will increase the Plant’s capacity and reliability for treating drinking water for San Francisco and San Mateo County.
Our Contractor, Kiewit Infrastructure West Co., is working in multiple areas within the Harry Tracy Plant, part of the Hetch Hetchy Water System Improvement Program. Seismic retrofits and electrical upgrades will allow us to reliably provide up to 140 million gallons of water per day, for 60 days, within 24 hours of a major earthquake. Harry Tracy serves several communities on the Peninsula in addition to San Francisco.
