Central & West Sewer Rehabilitation

The City of Columbia Sewer Utility is accepting public feedback on a proposed sewer rehabilitation project that will update sewers in many areas across central and west Columbia.

Thank you to everyone who joined us for our public meeting.

Information and diagrams showing preliminary concepts are available on this page.

The Sewer Utility has preliminary plans to rehabilitate sewer lines throughout the Flat Branch drainage basin, downtown, the Meredith Branch drainage basin and in the lower County House Branch drainage basin. Crews will rehabilitate approximately 120,000 feet of sewer pipe to repair structural deficiencies and to reduce occurrences of inflow and infiltration into the sewer main. The budget for this project is approximately $9.2 million and will be paid for by Sewer Utility funds.

The proposed method is trenchless and is less invasive than traditional methods. A contractor places a liner inside an aging pipe then blows steam to expand and harden the liner. The result is a reinforced pipe without a shovel breaking the dirt.

This page will be updated throughout the life cycle of the project. Please check back for any updates.
