Reducing pollution. Being a catalyst for environmental change, one project at a time.
CLEVELAND, OHIO – Since 2016, we have provided construction inspection services to the Northeast Ohio Regional Sewer District (NEORSD) for the four yearlong E. 140th St. Relief and Consolidation Sewer Project. This project is part of Project Clean Lake, a 25-year program to reduce pollution to Lake Erie and its tributaries.
When completed in 2020, the E. 140th St. Relief and Consolidation Sewer Project, spanning between the East side of the City of Cleveland near Bratenahl, OH, and East Cleveland, OH will redirect the sanitary sewers of several neighborhoods to a new connection to the Heights-Hilltop Interceptor which, via gravity flow, conveys sewage to the Easterly WWTP for treatment. Provisions are also included to redirect combined sewer overflows (which typically occur during a rain or melt event) to temporary storage via a connection to the future Dugway Storage Tunnel.
The E. 140th St. Relief and Consolidation Sewer Project consists of approximately 14,000 linear feet of 60-inch to 84-inch pipe-in-tunnel, 8 access shafts, a gate control vault, 6,800 feet of 12-inch to 54-inch diameter consolidation and relief sewers, an 84-inch diameter overflow sewer, a new regulator structure and connection to the Heights-Hilltop Interceptor, three stormwater detention basins, 12,000 feet of 12-inch to 54-inch diameter storm sewers, regulator improvements, junction chambers, and other sewer improvements.
Working with District personnel as well as other team members including the design engineer, other inspection firms and a variety of contractors, H.R. Gray has provided ongoing inspection services. The large scope of this project requires extensive coordination with all parties involved to ensure timely execution of tasks.
