USACE partners with Cahokia Heights, Illinois on sewer improvements

May 18, 2023
The USACE St. Louis District entered a cost-shared partnership with the City of Cahokia heights for a trenchless sewer rehabilitation project, improving wastewater conveyance and reducing overflows.

The U.S. Army Corps of Engineers (USACE) St. Louis District announced that it has entered into a cost-shared Project Partnership Agreement for sewer improvements in the City of Cahokia Heights, Illinois.

The sewer improvements are part of the Sanitary Sewer Trunkline Project. The $4.67 million project will involve trenchless sewer rehabilitation of the largest, deepest, and most downstream sections of the main sanitary sewer trunkline conveying flow through the city. The improvements will correct pipe deficiencies, restore structural stability, and ensure long-term reliability for the sewer conveyance system.

The Sanitary Sewer Trunkline Project is located primarily within city collector streets spanning from intersection of Jerome and Mousette lanes and continues in a westerly direct to the Levin Drive Sanitary Pump Station. These neighborhoods regularly experience street flooding, basement backups and yard flooding due to the deteriorating sanitary sewer system that results in increased inflow and infiltration in the system. This project will assist with rehabilitation of the main trunkline to reduce sewer backups into homes and overflows into receiving water.

"Infrastructure improvement projects like this are the result of partnerships among federal, regional and local agencies.," said Lt. Col. Thomas Sears, deputy commander of the USACE St. Louis District. "We are extremely proud of this project and the economic and environmental benefits it will provide to the Cahokia Heights community. This agreement we are signing today gives us the latitude for future phases moving forward.”

The St. Louis District’s environmental infrastructure programs assist communities with building, designing and/or restoring environmentally friendly water supply and wastewater treatment systems. As of this year, the district has assisted more than 10 communities in eastern Missouri and western and southern Illinois in building or rehabilitating projects.
