Sheridan Trunk Sewer Project-Duniway Park

Sewer and Stormwater
Environmental Services is designing a project to repair or replace several hundred feet of aging, large-diameter public sewer pipes in Duniway Park. Having provided over 100 years of service, the pipes require repairs to maintain reliable sewer service and protect public health and the environment.
Design started in March 2021 and will continue over the next two years. Construction is currently scheduled to begin May 2023 and will take up to a year to complete.

The project also includes relocating a mainline public sewer pipe from private property south of Sam Jackson Road near Duniway Park. Relocating the pipe will improve sewage flows and increase accessibility for future maintenance.

Project Area

The project is located in Duniway Park and in SW Sam Jackson Park Road just west of Duniway Park.  

What's Happening Now

Work crews will periodically be in the project area to perform investigative activities. Activities include site visits and evaluation, soil sampling, survey, utility locates, pipe cleaning and inspection. Some investigative activities may require restricting parking and closing travel lanes. 

Information gathered gathered will help determine the repair locations, select construction methods, and minimize construction impacts on residents, park users, and businesses.
