Last Seismic Improvement Pipeline Project Approved for Hetch Hetchy Water System

The San Francisco Public Utilities Commission (SFPUC) has approved the $42.5 million Peninsula Pipeline Seismic Upgrade Project (PPSU). The project will repair and replace sections of several water delivery pipelines located in northern San Mateo County to ensure these critical pipelines can withstand a major earthquake. The San Francisco Planning Commission approved the project’s Environmental Impact Report on October 17, and the SFPUC’s actions yesterday will send the project to bid. This is the last water pipeline improvement project to move into construction of the more than 80 infrastructure projects as part of the $4.6 billion Water System Improvement Program (WSIP). 

“When completed, the newly upgraded pipelines will provide the residents and businesses of northern San Mateo County and San Francisco even more assurance that water will be available for firefighting, drinking and operational use following an earthquake,” said SFPUC General Manager Harlan Kelly, Jr.

Emergency Preparedness Month

The First 72 Hours
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.

Pipeline Upgrade in Millbrae Reaches Final Phase

This fall, the contractor is working on the final phase to seismically upgrade the water pipeline located underground along the hillside behind Meadows School in Millbrae.  This pipeline conveys drinking water from the Harry Tracy Water Treatment Plant to the Peninsula.  

Phase 2 of pipeline upgrade 

Project Schedule 

Phase 1: Completed in June 2013.

Phase 2: Completed in August 2013.

Phase 3: October 1^st – December 15^th (dates subject to change). 

Equipment mobilization and material delivery will begin the week of October 1.

This phase includes excavation, welding and concrete placement for “sliplining”, placing a new steel pipe inside the existing pipe.  

Work hours will be 7:00 am to 7:00 pm. Construction truck traffic can be expected. This will be the most intense phase of construction.

We are coordinating our work around Meadows School and Happy Hall’s drop-off and pick-up schedules for safety and convenience. 

We aim to minimize construction impacts to the surrounding neighborhood and schools. We apologize in advance for any disturbance or inconvenience and invite you to call our 24-hour phone line at 

(866) 973-1476 or email us at peninsula@sfwater.org with questions or concerns. Visit the project website at www.sfwater.org/Peninsula for more information.

Project Description

Our contractor, Kiewit Infrastructure West Co., is working in multiple areas within the Harry Tracy Plant, part of the Hetch Hetchy Water System Improvement Program. Seismic retrofits and electrical upgrades will allow us to reliably provide up to 140 million gallons of water per day, for 60 days, within 24 hours of a major earthquake. Harry Tracy serves several communities on the Peninsula in addition to San Francisco.

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. 15^th to Dec. 15^th, 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 1^st. 

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.

Upcoming Construction Near Helen Drive

Starting the week of June 10th, the Harry Tracy Water Treatment Plant will conduct work in three phases during 2013 behind Meadows Elementary School on Helen Drive in Millbrae. 

A major water pipeline that brings drinking water from Harry Tracy to the Peninsula is located underground along the hill behind Meadows School. This construction project is a seismic upgrade to the pipeline by “sliplining”: placing a new steel pipe inside the existing pipe.

We are coordinating our work around Meadows School and Happy Hall's Summer Camp drop-off and pick-up schedules for safety and convenience. The work will take place on the hillside and a staging area will be located on the north end of the school parking lot. 

Project Schedule

Phase 1: June 10^th – June 14^th 

Phase 2: July 9^th – July 26^th

Phase 3: September 23^rd – December 15^th

Phases 1 and 2 entail exploratory and preparatory work, while the sliplining will occur during phase 3. Phase 1 will be exploratory work to equip the project engineers with precise mapping and geological data. Work hours will be between 7:00 am and 5:30 pm. 

Phase 2 will include a drill rig and a crane to install support structures needed for phase 3. Phase 3 will be the most intense period of work. 

Construction truck traffic can be expected in all phases of work. Temporary fencing will be placed along the north end of Meadows School’s parking lot for construction access only. We will notify residents and school parents with reminders and more details closer to the work dates.

We aim to minimize construction impacts to your neighborhood and schools.
