Third Avenue Relief Sewer – Phase 3

This project includes design and construction of a replacement / relief sanitary sewer along West Third Avenue between Edgehill Road and Northwest Boulevard. The project also includes new and replacement concrete sidewalks and curb ramps to complete a continuous pedestrian path from Edgehill Road to Northwest Boulevard.

The project is included in the City of Columbus Integrated Plan and 2015 WWMP Update Plan originally approved by Ohio EPA in December 2015 to address wet weather issues in the collection system.

The project will install approximately 2,800 LF of new 36 inch sanitary sewer, manholes, bedding and service connections to mitigate activations at four Designed Sanitary Reliefs (DSRs: 105, 110, 151 and 154).  The existing 10, 12 and 15 inch sanitary sewer will be abandoned in place.

The project area is on West Third Avenue from Edgehill Road to Northwest Boulevard. View the project area map(PDF, 93KB).

Pending final approval from OEPA, construction will start second quarter of 2022 and be completed second quarter of 2023.

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 letter(PDF, 299KB) of "Notice of Issuance of a Limited Environmental Review and Final Finding of No Significant Impact to All Interested Citizens, Organizations and Government Agencies."
