A Discussion of the Brewery District Sewer Improvements—Franklin Main Interceptor Sewer Rehabilitation Project in Columbus, Ohio

For more than a decade, the City of Columbus, Ohio has utilized trenchless technology to renew its existing infrastructure. A renewal method popular with the City is cured-in-place pipe (CIPP), technology that has been used extensively to rehabilitate its collections system in the historic, congested and heavily traveled areas of downtown. Many of these sewers are brick combination lines or interceptors that were originally installed as early as the late 1800's. The City's recent focus to revitalize these downtown areas has led to new development that is attracting more businesses and new permanent residents. One such community, the Brewery District, is undergoing a major facelift. Located just south of downtown, an area that was once an eyesore is developing into a local attraction. Improvements to the infrastructure have been given a high priority in areas of development. This report discusses the "Brewery District Sewer Improvements — Franklin Main Interceptor Sewer Rehabilitation Project" constructed by Rinker Pipeline Renewal (formerly CSR Hydro Conduit — Pipeline Rehabilitation). The project was funded by the city and private developers and involved the renewal of the southern section of the Franklin Main Interceptor with National Liner^TM CIPP, installation of new precast structures, pipe preparation, cementitious grouting and manhole rehabilitation. The CIPP lining operation was accomplished in two (2) setups; currently the longest and largest successful inversions of National Liner^TM ever recorded.
