The Crystal Springs/San Andreas Transmission System Upgrade project team will be pouring concrete at the Harry Tracy plant September 17 through 19 (Monday to Wednesday) from 2 p.m. to 7 p.m. Truck traffic on Crystal Springs Road in San Bruno is expected during those hours, with flaggers and pilot cars directing the concrete deliveries.
A special type of concrete --called cell-crete, an aerated and foam-like concrete-- will be used for this work. The machinery may be louder than the typical concrete pours that have taken place at the plant this year. Noise monitors will be present to ensure compliance.
The Harry Tracy Water Treatment Plant treats water from nearby San Andreas Lake before that water is distributed to our wholesale customers. The evening concrete pours at the plant this week are part of the ongoing seismic improvements to this critical transmission system.
Crews have made tremendous progress on the reservoir foundation and are on schedule for an early October completion of pile driving.
