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. The project will rehabilitate existing sanitary sewers within the City of Columbus, reducing inflow and infiltration to the City’s sanitary system and mitigating sanitary sewer overflows to basements and waterways.
This project rehabilitates sewers using cured-in-place pipe (CIPP). CIPP lining is a cost-effective, trenchless method for repairing damaged sewer or water pipes without excavation, typically lasting over 50 years. It involves inserting a resin-coated, flexible liner into the old pipe, which is then cured with heat, steam, or UV light to create a new, durable pipe inside the existing one. This method provides for fast installation, minimal property damage, improved flow, and high corrosion resistance.
This is a consent order project. The City entered into two consent orders (2002 and 2004) with the Ohio EPA to eliminate sewage backups and combined sewer overflows during wet weather. To comply with the consent orders, the City developed the Wet Weather Management Plan in 2005 which evolved into Blueprint Columbus, an integrated, greener approach utilizing sewer lining, roof drain redirection, sump pumps, and green infrastructure to handle rain water instead of relying totally on underground sewers. This plan serves as a national model, aiming to meet environmental regulations while enhancing neighborhoods and mana...
