M-29 Outfall Improvement Project

Completed Sewer

We rehabilitated the 100+ year old M-29 combined sewer outfall and replaced the endwall on the Monongahela River. The project improvements will extend the useful life of the outfall, reduce river flow entering the combined sewer system, and begin to mitigate backups into the lower Four Mile Run neighborhoods.
