Description
Project Description:
The City intends to replace the two parallel 8-inch concrete sewer lines along Columbia Avenue N.W. with one 15-inch polyvinyl chloride (PVC) sewer line. The project will include reinstating sewer service to residences, installing new manholes, and all work required to replace the sewer lines.
Project Justification:
In 2022, the City performed a closed-circuit television inspection of the sewer lines along this stretch of road. The inspection identified deficiencies, including root intrusions, pipe sags, and failed joints, and revealed that both sewer lines were reaching capacity during high demand periods. Replacing the existing concrete sewer lines with a single PVC line will ensure capacity requirements for the area are met.
