Project Overview

Environmental Services is continuing construction on a project to repair or replace about 16,331 feet (over three miles) of 100-year-old public sewer pipes in the Montavilla Neighborhood, north of Stark Street, that are deteriorating due to age. The project will also install 15 new manholes, repair 72 manholes, and replace 221 public sewer connections to private properties. This investment in your neighborhood will ensure continued dependable sewer service and protect the public and our environment by reducing the possibility of sewage releases to homes, businesses, and streets.

Another project in the Montavilla Neighborhood, south of Stark Street, is also being designed. For more information about the Montavilla South project, click here.


Construction is expected to continue through December 2019.
