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 10th – June 14th 
Phase 2: July 9th – July 26th
Phase 3: September 23rd – December 15th

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.
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. 

Project Description 
Our contractor, Kiewit Infrastructure West Co., is working in over 20 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.
