Project Background

Underground water and sewer pipes that are approaching the end of their useful life will be upgraded to maintain critical utility services and avoid disruptive emergency repairs.

In addition to replacing water mains and sewer mains, this project will also install earthquake resistant ductile iron pipe that will be part of the seismic backbone for water support to San Francisco General Hospital in the event of an earthquake.

The project will also build curb ramps to facilitate accessibility in accordance with the Americans with Disabilities Act.
