Water and Sewer

Mine Creek Outfall Gravity Sewer Replacement

Replacement project to prepare sewer system for wet weather events that may produce higher amounts of storm water.

We’re excited to announce an important upgrade to our sewer system designed to handle increased stormwater and keep our community safe and resilient.

This project will improve approximately 15,500 linear feet of gravity sewer with larger-diameter pipes and 13,000 linear feet of existing pipe with a structural liner. These upgrades will help the sewer system better manage wet weather flows, protect it from potential damage, and extend its useful life.

The work will begin near Crabtree Creek by I-440, continue along Mine Creek to West Millbrook Road, and extend along both the east and west sides of Shelley Lake up to North Hills Drive. To complete the project, crews will make necessary road crossings at North Hills Drive (two locations), West Millbrook Road, and Shelley Road.

We appreciate your patience and understanding as this important work takes place, and we’re committed to keeping the process safe, efficient, and minimally disruptive.

History

The existing sewer line is currently unable to handle heavy rain events, and its limited capacity has sometimes caused backups. Water modeling confirmed that during severe storms, there’s a risk of sanitary sewer overflows. This finding helped secure funding for the project.

A design option was selected, and the project engineer moved forward with the Preliminary Engineering Report (PER) and pre-design work. In January 2021, a meeting was held to review the PER, which has now been completed.

Brown and Caldwell conducted a detailed cost analysis for the design, submitted in Fall 2021, and completed the final design in 2025 to support required permit applications. The permitting process began shortly afterward, and review meetings with the City were held at key milestones throughout the design process.
