Portage Interceptor Sewer Rehabilitation Project

On April 18, 2022, the City of Portage, IN broke ground on its $1.5M Sewer Rehabilitation Project.

Mayor Sue Lynch, Col. Paul Culberson, Commander, U.S. Army Corps of Engineers Chicago District, Mark Lopez, Chief of Staff for Rep. Frank Mrvan of IN 1st District, representatives from the City, Commonwealth Engineers, and Grimmer Construction, gathered to celebrate the construction kick-off for this project.

Project Purpose

The purpose of this project is to reduce excess flow in the wastewater system due to inflow and infiltration and to reduce the risk of sanitary sewer overflow events adjacent to wetland areas.

Project Description

The proposed project extends from Stone Avenue in the south up to Central Avenue in the north. This section of the interceptor is approximately 4,600 feet in length. It includes 30-inch and 36-inch diameter reinforced concrete pipes (RCP) along with two (2) 20-inch diameter siphon pipes. The siphon is restricting flow in the interceptor so a third pipe will be added. The existing siphon structures are in poor condition and are being replaced. Weirs are being constructed to improve the hydraulics and the siphon. The interceptor will be lined with cured-in-place pipe (CIPP) from Stone Avenue to the siphon. Some manhole rim elevations are below the 100-year floodplain elevation and will be raised as part of this project as well. This project is part of the Calumet Region Environmental Infrastructure Section 219 program and has been allocated $1,437,500 of federal funding.

The contract was awarded to Grimmer Construction, Inc. of Highland, IN for $1,532,076.
