What to Expect During Construction

  • The contractor will be working Monday through Friday, from 8 a.m. to 5 p.m.
  • Most construction will be using the Open Trench method. The Trenchless Method (slip-lining) is planned for road crossings at San Bruno Avenue, Cherry Avenue and Sneath Lane.
  • Parking will be restricted in the work zone. Please see posted signs for exact details.
  • No interruption in water service or quality is expected during construction.
  • Neighbors should expect some noise and limited dust during this work. The project team will work to minimize disruption to normal neighborhood activity; however there will be occasional inconveniences due to heavy equipment movement and other construction activities.
  • Residents in the work zone will maintain access to their garages, although there may be temporary delays.

The Hetch Hetchy Regional Water System is owned and operated by the San Francisco Public Utilities Commission (SFPUC), a department of the City and County of San Francisco. The system provides drinking water to 2.7 million people in Alameda, Santa Clara, San Mateo and San Francisco counties.
