Project Overview

Environmental Services will begin construction the week of April 8, 2019, on a project to extend the public sewer system in NW 24th Avenue between NW Thurman and NW Raleigh streets. The project will construct 248 feet of mainline public sewer pipes, 3 manholes, and 75 feet of service laterals, which will connect private properties to the new public sewer. This project will provide public sewer service to a new development and resolve nonconforming sewer connections for three properties.


The project will construct two sewer extensions in NW 24th Avenue – one south of NW Thurman Street and another south of NW Savier Street.

Project Map


Construction will begin the week of April 8, 2019. The project will take up to two months to complete. General work hours will be from 7 a.m. to 6 p.m., Monday through Friday, and Saturday if needed.

Construction Methods

Crews will install mainline public sewer pipes using open trench excavation. It will be necessary to dig a trench in the street to install the pipes. Crews will construct sewer service laterals using a trenchless method to avoid an existing telecommunications line and other utility conflicts in the public right-of-way.

After sewer construction, crews will backfill the trenches and apply a temporary asphalt patch. After all work has passed inspection, crews will return to restore the patched trenches with a fresh new asphalt surface.
