Harry Tracy Work Schedule Update

The Harry Tracy Water Treatment Plant is scheduled to resume full operations by April 1st. Since late February, water treatment has been “shut down” to allow for specific construction activities.

The weekend of March 22 and 23, the project team will work both Saturday and Sunday from 7 a.m. to 5 p.m. We expect indoor activities only before 9 a.m. and on Sunday.

The plant is typically online during construction, drawing and treating water from the Crystal Springs Reservoir System for delivery to wholesale customers. To accommodate project construction and connections to the system, it is taken off-line for limited periods.

If you have any questions or concerns about the project, please call us 24-hours a day at (866) 973-1476.

Truck Hauling on Helen Drive, March 10 to 14

Crews from the nearby Crystal Springs/San Andreas Transmission System Upgrade project are seismically reinforcing a tunnel at San Andreas Lake.

From March 10th through 14th , trucks will be using the Helen Gate entrance of the Harry Tracy Water Treatment Plant to deliver a lightweight type of concrete called “cell-crete.”

We expect approximately 10 round trips a day along Helen Drive in Millbrae during the project work hours, 7 a.m. to 6 p.m. Flaggers will be present for safety and trucks will be scheduled to avoid the Meadows Elemetary School drop-off and pick-up times.

A wheel washing station is set up at the plant’s exit to clean truck tires before they return to Millbrae streets.

Please call us 24-hours a day with any questions or concerns about this work at (866) 973-1476.

San Bruno Traffic Advisory for March 3rd and 4th

On Monday morning, March 3rd, a large crane will be delivered to the Harry Tracy Water Treatment Plant in San Bruno before 7 a.m. in order to avoid the morning rush hour. The crane will be escorted and piloted up Crystal Springs Road from Cunningham Drive.

On both Monday and Tuesday, March 3 and 4, large machinery will be delivered to the plant between 9:15 a.m. and noon. We expect traffic delays on Crystal Springs Road between Cunningham and Crestmoor Drive during these periods.

Traffic control specialists will direct traffic through one open lane on Crystal Springs Road for most of the morning. The entire road will close for approximately 10 minutes for the equipment to turn the corner into the plant entrance.

Please call us at (866) 973-1476, 24-hours a day, with any questions or concerns.

Harry Tracy Construction Update

Saturday Work
This Saturday, February 22nd, our neighbors along Crystal Springs Road may hear more noise than usual, as work continues on a small building close to the main road. A noise monitor will be present to ensure compliance with local limits. Saturday work hours are 9 a.m. to 5 p.m. No work is scheduled for Sunday. 

Helen Drive in Millbrae
From March 10th through 14th, crews for the Crystal Springs/San Andreas Transmission System upgrade project will seismically reinforce a tunnel at San Andreas Lake.

Limited truck hauling is planned on Helen Drive to deliver materials via the Helen Gate entrance. Approximately 10 round trips per day are expected during the hours of 7 a.m. and 7 p.m. Flaggers will be present to ensure safety.

Night Work
This month marks our sixth full plant shutdown since the project began in March 2011.

The plant is typically online in order to draw raw water from the Crystal Springs Reservoir System and treat water for our wholesale customers. Plant operations are occasionally “shut down” for designated short periods to allow for intensive construction.

Evening shifts and night work are not currently planned, but could be scheduled any time between now and April 1st. The project work hours are 7 a.m. to 7 p.m., Monday to Friday, and Saturdays 9 a.m. to 5 p.m.

You may notice increased daytime work during this period. If a night shift is scheduled, the project team will make every effort to keep activities limited to indoor work. Please subscribe (see right) to this site for automatic schedule updates.

Please call us 24 hours a day at (866) 973-1476 with any questions or concerns.

The Crane’s Eye View

By mid-December, the Harry Tracy Water Treatment project will conclude two months of intensive work on new pipeline segments and upgrades to the treatment plant.  During this period regular operations have been suspended.  The project is over 65% complete, thanks in part to the swing shift started earlier this year to complete the new treated water reservoir. When the Plant comes back online later this month, the swing shift is expected to conclude. Extended hours and swing shifts may again be required in the future to stay on schedule or due to the demands of the work.

Work will continue throughout the Plant from 7 a.m. to 5 p.m. including most Saturdays from 9 a.m. to 5 p.m.
Steel-reinforced concrete columns are currently being constructed inside the new 11 million gallon treated water reservoir (photo above). The yellow metal forms are reused after each column has hardened. The columns will soon support a reinforced concrete roof. Waterproofing and water quality testing will follow before placing the new reservoir into service. 
Meanwhile construction of the reservoir walls is almost finished. The inner wall is more than 75% formed, and the outer wall is now complete except for a temporary opening for equipment and materials.


These new below-grade filters will increase our reliability 
to process raw water into drinking water.


What to Expect

  • Building materials are delivered via Crystal Springs Road in San Bruno. Flaggers control truck traffic at the Plant gate and pilot cars escort trucks along the road for safety.
  • Truck off-hauls occasionally begin at 7:00 a.m.
  • Noise levels are monitored to maintain compliance with local ordinances.

The contractor is working to minimize disruption to our neighbors. Please don’t hesitate to call our 24-hour phone line at (866) 973-1476, or email peninsula@sfwater.org with questions or suggestions.
