Eliminating Sewer Overflows Protects the Environment

Collaborative project delivery for phased construction to convert the City of Euclid’s conventional wastewater treatment plant to membrane bioreactor (MBR) technology.


Minimizing sewer overflows requires change, and Euclid entrusted Kokosing to help them make the changes to their system.  The project includes construction of a new headworks facility, retrofitting the existing treatment process tanks with the new membrane bioreactor system, a new wet weather equalization tank and relief sewer. The construction of the Edgecliff Relief Sewer provides emergency bypass for peak flows beyond design capacity, and the new headworks complex will provide coarse screening, fine screening, grit and grease removal and flow metering. Additionally, the project includes improvements to process piping, pumping equipment, electrical systems, control systems and site work.


Many communities are working to eliminate sewer overflows during rain events or other times of system overcapacity.  The City of Euclid is working to tackle this same issue in their own system. Kokosing’s experience in constructing and restoring wastewater treatment plants spans decades and contributes to our ability to provide innovative insights on projects, such as this one for the City of Euclid.  The Construction Manager at Risk (CMAR) model allowed Kokosing to add value by evaluating scope options, constructability and the budget during all phases of the project.

Kokosing was the right choice for this project and is already demonstrating this knowledge in the design phase by providing important constructability and value engineering input.
