Final Phase of Pile Driving at Harry Tracy

Pile driving at the Harry Tracy Water Treatment Plant (located off Highway 280 near San Bruno and Millbrae) is expected to begin on August 7^th and continue for approximately 6 to 8 weeks. This will be the final phase of pile driving for the new 11 million gallon treated water reservoir.  The new reservoir will allow us to provide up to 140 million gallons of water per day, for 60 days, within 24 hours of a major earthquake.

The Harry Tracy plant is also expanding water filtration capacity as part of the ongoing construction. Beginning next week and continuing for 3 weeks, trucks will off-haul excavated soil from the site of the new filters. All trucks go through the wheel washer before leaving the plant to prevent tracking dirt onto Crystal Springs Road, and truckloads are securely covered. In addition, soil is tested before the off-haul to ensure there are no contaminants present. Truck hauling will operate between 7:30 a.m. and 4 p.m. Pilot cars will continue to escort trucks along the road to restrict speed and ensure safety.

Please call us with any questions or concerns about the upgrades and seismic improvements underway at the plant at (866) 973-1476.
