Construction Update for San Bruno and Millbrae

Forming the walls of the 11 million gallon
treated water reservoir
Seismic and reliability upgrades are continuing at over 20 locations in the Harry Tracy Water Treatment Plant. A swing shift will continue to operate until 2:00 a.m. most Mondays through Saturdays. Construction lights used in work areas may be visible during the evenings; however, the contractor is working to minimize any disruption to nearby neighbors.  

San Bruno Update
Truck off-hauls from the site will occasionally begin at 7:00 a.m. Concrete trucks and other material deliveries will continue along Crystal Springs Road in San Bruno.

The new 11 million gallon treated water reservoir is over 60% complete as its concrete walls are forming into a full circle. The next structural installations will include 49-foot tall columns to support a “floating” cap with points of contact rather than an attached roof, to help the reservoir withstand a major seismic event.

Millbrae Update
An intensive period of work is scheduled from Oct. 15th to Dec. 15th, when the contractor will be sliplining the Millbrae pipeline. A new steel pipe will be placed inside the existing pipe that runs from the Plant down the hill to Helen Drive, behind Meadows School and Happy Hall Daycare. Equipment mobilization and materials delivery will begin the week of October 1st. 

Upon completion of construction, the treatment plant will be able to reliably provide up to 140 million gallons per day, for up to 60 days, within 24 hours following a major earthquake on the San Andreas Fault.

We strive to minimize disturbances to surrounding neighbors. The contractor monitors noise levels to maintain compliance with local ordinances. Flaggers regularly control traffic at the Plant gate on Crystal Springs Road and pilot cars escort trucks along the road for safety.

Please don’t hesitate to call our 24-hour phone line at (866) 973-1476, or email us at peninsula@sfwater.org with questions or concerns.
