The Wastewater Utility implements an annual sanitary sewer rehabilitation and/or replacement project as part of its ongoing capital improvement program. The replacement project consists of various sewer main, manhole, and side sewer replacements. The sewer infrastructure to be replaced was chosen based on the severity of existing issues found through field observations and inspections. The project is located within city right-of-way and on private property within city easements.

This project will fix or replace defective sanitary sewer facilities in seven different sites in the north half of Renton and is divided into two phases. Phase 1 is comprised of right-of-way work for Sites 1, 2, 3 and 6. Phase 2 is comprised of private and right-of-way work for Sites 4, 5 and 7.
