This project will redirect Moler Street Regulator combined sewer overflows that discharge to Scioto River into OSIS Augmentation and Relief Sewer (OARS) Shaft 3. When constructed, the Moler Street Overflow Intercepting Sewer will convey both Moler Street regulator combined sewer overflows and South Side Interceptor sewer wet weather flows into OARS Shaft 3.
The project area is generally bounded by: W. Moler Street on South, S. High Street on East, Scioto River on West and W. Gates Street on North. View the project area map(PDF, 87KB).
Pending final approval from OEPA, construction will start summer of 2024 and be completed fall of 2025.
Financing for this project is being provided by a below-market rate loan obtained through the OEPA’s Water Pollution Control Loan Fund (WPCLF) and the debt is being serviced through the City of Columbus sanitary sewer user fees.
The Ohio EPA has completed a Limited Environmental Review (LER) for this project. View the LER and the letter(PDF, 605KB) of "Notice of Issuance of a Limited Environmental Review and Finding of No Significant Impact.”
