Hayes Sewer Improvements Project
Overview
As part of the SFPUC's wastewater capital investments, the Hayes Sewer Improvements Project will rehabilitate the existing 100+ year old sewer mains located under several streets located Hayes Valley.
-
Project Background
Wherever possible and to minimize impacts to the roadway and adjacent residences and businesses, most of the sewer mains will be rehabilitated with a trenchless method called Cured-in-Placed Pipe (CIPP). Where CIPP cannot be performed, the sewer mains will be replaced or rehabilitated with open-excavation. Construction will include improvements to sewer lower laterals within the project area, which may also require open-excavation. When completed, this project will increase the reliability of our City’s critical sewer system infrastructure.
