Blacklick Creek Sanitary Interceptor Sewer, Section 6, Parts B & C (BCSIS)
Columbus/New Albany, OH
The Blacklick Creek Sanitary Interceptor Sewer, Section 6, Parts B & C (BCSIS) project consists of extending the existing sanitary sewer approximately 4.5 miles to the north using tunneling and shaft construction methods to expand service to the northeast region of Columbus and surrounding communities. This project will allow for future connection of the Rocky Fork Sewershed and the BCSIS tunnel will be constructed using a segmental concrete liner with a finished diameter of 10- to 12-feet. The depth of the BCSIS tunnel varies from 40-feet below grade at the southernmost end at Blacklick Ridge Boulevard to 140-feet in depth at the northern terminus at the intersection of Morse Road and Reynoldsburg-New Albany Road. These improvements will increase the Blacklick Tributary Area to 20,000 acres and provide the City of Columbus with improved sanitary system flexibility and management with future connection to the Rocky Fork sewershed. The project is estimated to cost approximately $125 million and construction will be completed by 2020.
