2021 Annual Lining Contract

Sewer lining using trenchless tech

CIP# 650404-100048will rehabilitate existing sanitary sewer mains and manholes within the City of Columbus. The sanitary infrastructure within Columbus includes miles of older sewer that have outlived their useful service life. These sewers are more prone to leaks and/or failures that may occur unexpectedly. This project has the added benefit of reducing the amount of inflow and infiltration of non-sewerage waters to the sanitary sewer system, thereby reducing occurrences of water in basements and sewerage overflows to area streams and rivers.

The project includes over 47,000 linear feet of 8-inch to 18-inch diameter sewers and 300 manholes. The sewers will be rehabilitated using cured-in-place pipe (CIPP) methods and the manholes will be rehabilitated with a cementitious liner. Construction is expected to begin in spring 2022.

Area residents will receive notifications prior to the work being performed. The notifications will give information on timing of the work, contact information and a request to restrict water usage for the short time (8-10 hours) while sewer main is being CIPP lined.

Financing for this project is being provided by a below market-rate loan through the OEPA’s Water Pollution Control Loan Fund (WPCLF) Program. Prior to granting this loan, the Ohio EPA required a detailed submittal from the Division of Sewerage and Drainage to determine the project’s eligibility.

The Ohio EPA has completed a Limited Environmental Review (LER) for this project. View the letter(PDF, 434KB) of "Notice of Issuance of a Limited Environmental Review and Final Finding of No Significant Impact to All Interested Citizens, Organizations and Government Agencies."
