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 St. regulator combined sewer overflows and South Side Interceptor sewer wet weather flows into OARS Shaft 3.
Also included is the design to redirect Moler Street Storm Sewer to convey stormwater flow to the Scioto River by flowing north along High St. and west along Gates St. The redirected Moler Street Storm Sewer will address Water in Basement occurrences with future inflow redirection within the Moler combined sewer area.
This project is included in the City’s combined sewer overflow Consent Order and must be operational by July 1, 2025.
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.
Pending final approval from OEPA, construction will start winter of 2023 and be completed summer of 2024.
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.
