Merrill Street Combined Sewer Rehabilitation
Dealing with increasingly ailing infrastructure and the need to “go green” when possible, the Indianapolis Department of Public Works (DPW) contacted Wessler Engineering to provide services for the rehabilitation of the Merrill Street sewer to extend its useful life and increase pipe capacity.
The Merrill Street combined sewer is a 60 to 66-inch reinforced concrete sewer handling both sanitary and stormwater flow through the heart of downtown Indianapolis. Installed in the late 1940s and roughly 30 feet deep, the sewer serves two major downtown customers: Eli Lilly & Company and the U.S. postal hub. Approximately 2,900 linear feet of sewer was rehabilitated along Merrill Street.
The selected rehabilitation method was Cured in Place Pipe (CIPP) with this project featuring the largest diameter CIPP liner DPW had undertaken. The project crossed five major thoroughfares without a single road closure.
The Wessler team was responsible for the design and bid phase and provided construction administration assistance for this landmark project.
