Project Clean Lake – Reducing Pollution, Protecting Our Water in Lake Erie, Northeast Ohio

Project Clean Lake was developed to address ongoing water quality concerns resulting from the discharge of untreated sewage during heavy rain events. The program will reduce sewage overflows into Lake Erie by over 4 billion gallons per year, improving both the environmental and public health of the region.

At the heart of the project are seven massive underground tunnels, ranging from two to five miles in length and up to 24 feet in diameter, designed to store excess stormwater and sewage during rain events. This stored water will then be treated, preventing the overflow of untreated sewage into local waterways.

Wastewater Treatment Plant Pipe Rehabilitation Design in Cincinnati, OH

Using Danby liner and grout, Stiver Engineering provided a pipe rehabilitation design for a 93-inch arch pipe at a wastewater treatment plant in Cincinnati, Ohio. The existing pipe section along with the Danby liner and grout allowed us to create a composite section. The composite section was designed so the contractor could provide a clear span over existing utilities. Stiver also designed bulkheads inside the existing 93-inch arch pipe to provide access for the pipe’s rehabilitation.
