Montavilla North Sewer Repair

Environmental Services continues construction of the Montavilla North Sewer Repair Project in the Montavilla Neighborhood (north of Stark Street). The project includes replacing or repairing more than three miles of deteriorating 100-year-old public sewer pipes, 87 manholes, and public sewer connections for 221 properties. These improvements will help protect the public and our environment by reducing the possibility of sewage releases to homes, businesses, and streets.

Location

The map below indicates pipe work locations and provides a construction update for the project.
