Project Summary
Current Phase: Planning
Sponsor Project Manager: Dung (Young) Huynh, Department of Transportation and Environmental Services
Managing Project Manager: Lindsay Burleigh, Department of Project Implementation
Project Description
Under the Old Town Combined Sewer Condition Assessment Project, two sanitary sewers at King and Strand were found to be in poor condition, which require them to be replaced. If they are not replaced, there is the potential for the sewer to collapse leading to sanitary sewer backups and sanitary sewage being discharged into the environment.
This project will replace a total of 110 feet of sewers, consisting of an existing 90 foot 8 inch sanitary sewer and a 20 foot 8 inch pipe in the 100 block of Strand Street near King Street. As part of the sewer replacement, the pipes will also be upsized to meet the City's design and construction standards.
The project consists of three phases with the planning phase to be completed by fall of 2024. The design and construction phases are anticipated to begin late 2024 and early 2026, respectively.

- Replacement Recommendation – Reviewed inspection reports and photos and it was determined that the two sewer segments at King/Strand were at a risk of failure and were proposed for replacement.
- Cost Estimate – a planning level cost estimate was performed for design and construction services.
