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

As we look back over 2013 we’d like to say “Thank You” to our neighbors for your cooperation in our work to upgrade the aging Hetch Hetchy Water System. We send you wishes for warmth, happiness and delicious clean water this holiday season and beyond.
All our best,

This October, take time to engage in your community, discuss ideas and plans, and prepare for an emergency or natural disaster. The SFPUC’s Emergency Preparedness Month encourages all San Francisco-area residents to become more aware and prepared for the next emergency, which is almost certain to take place in our lifetimes. The first 72 hours after an emergency are often the times when community members come together to help each other out. If we prepare beforehand, we’ll be better off when an emergency occurs.
What can you do?
Meet with your family, neighbors and community organizers to get connected, develop a plan and share resources. Use SF72.org and sfwater.org/BePrepared as starting points. You’ll find tips, guidelines for supplies, a mobile app and stories from real San Franciscans.
This is our city
SF72.org was developed by San Francisco for San Francisco. Let’s protect each other and our city by using our resources and knowledge to the fullest when an emergency strikes.
Our community members are not the only ones getting prepared. The SFPUC has been improving and renovating our regional water system to ensure a safe and reliable water supply. Although San Francisco will always need to rely on this imported water from the Sierras, we are also developing additional water supplies that can be used in the event that our regional system is disrupted. For example, we are developing local wells in San Francisco to blend high-quality groundwater with our imported water supplies, and we’re producing recycled water for non-drinking purposes to reduce the amount of drinking water currently used in these ways.
Check www.sf72.org or www.sfwater.org/BePrepared for more information.

Visitors to San Andreas Trail with an astute eye may observe water levels in San Andreas Reservoir rising late this spring as our new Crystal Springs Pump Station is tested during its final stages of construction. Located near Crystal Springs Dam, the new pump station will be able to transport water from Crystal Springs Reservoir to San Andreas Reservoir with 1/3 more capacity and using less power than the old pump station, which was last substantially upgraded in the 1920s. During the testing period this spring, San Andreas Reservoir is expected to rise approximately six feet.

Like the Crystal Springs-San Andreas Transmission System, the regional water treatment plant is also undergoing major seismic and capacity upgrades as part of the Water System Improvement Program (WSIP). The Contractor has completed pouring the base for the new 11-million gallon treated water reservoir. Crews continue to work on the addition of new filters, seismic retrofits of critical processing units, and upgrades to electrical and other systems.
We can genuinely say the Hetch Hetchy Water System is more seismically reliable today than it was a year ago. Upon completion of construction, the HTWTP will be able to sustain a capacity of 140 million gallons per day (MGD), for up to 60 days, within 24 hours following a major earthquake on the San Andreas Fault.

The April 18, 1906 earthquake ranks as one of the most significant earthquakes of all time. Beginning at 5:12 a.m., with the epicenter located near San Francisco, the shocks were felt as far north as Oregon and as far south as Los Angeles.

Trucking Hours: 7:00am to 7:00pm.
Pilot cars will regulate the speed and number of trucks entering and exiting the plant gate. Long work days are necessary to ensure the concrete base slab has adequate time to dry.
More information and exact dates of two additional concrete placement activities will be posted here on our blog, www.sfwater.org/Peninsula, and will be available by email - firstname.lastname@example.org - and on our 24-hour phone line, (866) 973-1476.
We are making every effort to minimize construction impacts to surrounding neighborhoods. Please don’t hesitate to call our 24-hour phone line or email us with questions or concerns.

Residents on Crystal Springs Road should allow extra time to enter and exit driveways.
The Harry Tracy Water Treatment Plant project will conduct intensive concrete pours on four days this month, starting on April 9th. These concrete “placement activities” will require a large number of trucks to travel along Crystal Springs Road in San Bruno to create the base slab for the new 11 million gallon Treated Water Reservoir.
Pilot cars will regulate the speed and number of trucks entering and exiting the plant gate. Long work days are necessary to ensure the concrete base slab has adequate time to dry in current weather conditions.

|Coating Application on the Treated Water Reservoir|
The Harry Tracy Water Treatment Plant project will conduct four intensive, one-day concrete “placement activities” to create the base slab for the new 11 million gallon treated water reservoir. These placement activities require a large number of trucks to travel along Crystal Springs Road in San Bruno. Pilot cars will regulate the speed and number of trucks entering and exiting the plant gate.
Exact dates and more information will be posted here on our blog, www.sfwater.org/Peninsula, and will be available by email - email@example.com - and on our 24-hour phone line, (866) 973-1476.
