Columbia, Mo., approves $9.2 million sewer rehab project using trenchless technology
(UI) — The Columbia City Council has approved plans to move forward with a $9.2 million sewer rehabilitation project aimed at upgrading aging sewer infrastructure across central and west Columbia. The decision came during a public hearing at the council's Dec. 2 meeting.
The project will focus on rehabilitating approximately 120,000 feet of sewer lines in key areas, including the Flat Branch drainage basin, downtown Columbia, the Meredith Branch drainage basin, and the lower County House Branch drainage basin. The updates will address structural deficiencies and reduce inflow and infiltration into the sewer main.
Funding for the project will come from Sewer Utility funds, and crews will use trenchless technology to minimize disruptions. The method involves placing a liner inside deteriorating pipes, which is then hardened using steam. This approach reinforces the pipes without the need for extensive excavation.
"This trenchless method is less invasive than traditional techniques and ensures a more efficient rehabilitation process," officials noted.
Preliminary designs and diagrams for the project are available for public viewing. Updates will be provided throughout the project's lifecycle.
