VIDEO: Peninsula Projects Launch at Crystal Springs Reservoir

On March 30th the San Francisco Public Utilities Commission (SFPUC) and Bay Area officials launched $320M in seismic and reliability upgrades to the Hetch Hetchy Regional Water System. Peninsula projects include improvements to Lower Crystal Springs Dam, Harry Tracy Water Treatment Plant, and Crystal Springs Pipelines. This event also marked the mid-point of this $4.6B Water System Improvement Program with active regional construction totaling $2 billion.

Removal of Construction Materials from North Shaft in San Mateo

With the seismically advanced New Crystal Springs Tunnel and Pipeline in service, the project team is in the process of demobilizing their equipment and materials from the construction sites in San Mateo.

Over the next several weeks, crews will begin removing construction related materials from the North Shaft site located near the intersection of Crystal Springs Road and Polheumus Road in San Mateo. Crews will remove equipment, grade the soil on site, backfill soil, remove fencing and remove the k-rail concrete protective structures along the site of the roadway.

Please drive the posted 10 m.p.h speed limit on Crystal Springs Road and be aware of workers, trucks and equipment in or near the roadway during this demobilization work.

Once they remove the posted 10 m.p.h speed limit signs, the speed limit will return to normal.

Shoulder Work on Polhemus Road in April

For the next few weeks, you may notice "Road Work Ahead" signs along Polhemus Road between the New Crystal Springs Bypass Tunnel 'South Shaft' site (near Bunker Hill Road) and Crystal Springs Road in San Mateo.

The contractor will have a few workers working along the shoulder of Polhemus Road. They will be grouting inclinometer holes in accordance with county and state monitoring well standards.

The New Crystal Springs Bypass Tunnel project is nearing completion and the new tunnel and pipeline are in service.

Town of Millbrae: Water Treatment Plant Upgrades

Water Treatment Plant Upgrades (Millbrae) - Last week of March:

Construction preparation work will be starting for upgrades to the Harry Tracy Water Treatment Plant. This plant treats drinking water from the Crystal Springs Reservoir System (Upper and Lower Crystal Springs Reservoirs and San Andreas Lake) for delivery to northern San Mateo County and San Francisco.

All work for this project will take place within the SFPUC property.

Residents near the northern end of Sycamore Drive and Crestview Drive in Millbrae may see some ground-clearing as the grounds within the Plant property are prepared for construction trailers. A visual and sound reduction fence will also be placed to maintain privacy for adjacent homeowners.

Work Begins at San Andreas Lake and Continues at Sawyer Camp Trail

Is the San Andreas Trail one of your regular hiking spots? If so, you may see workers near San Andreas Lake preparing for or beginning construction. San Andreas Trail will remain open for everyone throughout construction.

Water pipeline and structure upgrade projects are beginning in the area. Crews are mobilizing at the Lower Crystal Springs Dam to complete necessary hydraulic improvements to the dam.

Please Be Aware: Parking may become more limited near the Sawyer Camp Trailhead, as construction activity increases. The project team realizes that parking is already difficult at Sawyer Camp Trail, and will make every effort to preserve access. Stay tuned for more details!

Please contact us any time with questions or concerns. 24 hours a day, toll-free:

Pipeline work on El Camino Real starting in March

Do you drive along El Camino Real? Learn more about an upcoming pipeline project in the area. SFPUC contractor Ranger Pipelines plan to install the first segment of Crystal Springs Pipeline No. 2 (CSPL2) this May along El Camino Real. A second installation is planned this June in South San Francisco.

To prepare for pipeline installation, limited construction work will begin in late March and continue through April. This minor work will include potholing to locate underground utilities along El Camino Real. Some limited excavation may be required to locate utilities such as cable and telephone lines. In addition, some preparation for the pipeline installation access pits may be completed at this time.
