The WSIP Turns 10!

This year the Water System Improvement Program (WSIP) turns 10! One of the largest infrastructure projects in the nation, the WSIP is repairing, replacing and upgrading our aging water infrastructure to ensure we can deliver water to customers following an earthquake. We’ve gotten a little nostalgic about how far we’ve come in the last 10 years, and we would like to share this video with you.



Now 80 percent complete, the WSIP has already provided increased reliability to the water supply for customers as a result of the completion of some of the program’s major projects. The program has created over 6 million construction craft hours to date, employing more than 11,000 workers since 2007. Nearly half of those workers live in our four-county service area.

Upcoming Night Work at Harry Tracy

The project team expects night work to begin at the plant on Tuesday, May 27^th. The new shift is scheduled from 5:30 p.m. to 4:00 a.m., Monday through Friday until mid-July. Saturday work will continue as usual, 9 a.m. to 5 p.m.

This swing shift is needed to construct a 78-inch treated water pipeline within the plant property. The new pipeline runs through the main road of the plant. Work in this area must be scheduled at night to avoid conflict with daytime construction and normal plant operations.

The plant is currently online to treat water from the Crystal Springs Reservoir System and provide water to wholesale customers in San Mateo County.

Please subscribe to this site (see right) for automatic updates to the work schedule.

Night lighting is pointed downward and faced away from residential areas. Noise monitors will be present every night during the swing shift to maintain compliance with local ordinances, and deliveries are scheduled during the day shift.

Please call our 24-hour phone line at (866) 973-1476 with any questions or concerns.

Concrete Deliveries on Helen Drive – Monday, May 12th

Project crews expect three concrete trucks to access the Harry Tracy Plant via Helen Drive on Monday afternoon, May 12.    Deliveries will occur between 12:30 and 2:30 p.m., approximately one trip each way every thirty minutes.

Traffic control measures will be present where needed to ensure safety.

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

Latest Look Inside New Treated Water Reservoir

The Harry Tracy Water Treatment Plant project is nearly 80% complete and on schedule to finish major construction in December 2014.

Inside the new Treated Water Reservoir on April 15, 2014

Since work began in 2011, construction workers have logged more than 900,000 hours on the job for this important infrastructure investment. In recent months, the Contractor has continued building new filters, washwater tanks, and a new Treated Water Sampling Building.

The new 11 million gallon Treated Water Reservoir is the largest and most complex part of the Harry Tracy construction. The Contractor has completed concrete placement for each of the 88 columns inside the reservoir that will help it withstand a major seismic event. 

The plant is currently online and capable of drawing raw water from the Crystal Springs Reservoir System to provide to our customers. By December 2014, Harry Tracy will be able to reliably provide up to 140 million gallons per day, for 60 days, within 24 hours of a major earthquake on the San Andreas Fault.

Please call our 24-hour phone line at (866) 973-1476 with questions.

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.
