Dugway West Interceptor Relief Sewer Project Creatively Combining Trenchless Techniques to Complete the St. Clair Ave. Relief Sewer

摘要

Originally designed as an Open-Cut sewer installation, the westernmost terminus of the St. Clair Ave. Relief Sewer, part of the Northeast Ohio Regional Sewer District’s (NEORSD) $58 Million Dugway West Interceptor Relief Sewer (DWIRS) Project, had its share of potential pitfalls. Faced with the prospects of required utility relocations estimated to exceed $2 Million, and several months of traffic hassles resulting from the long-term closure of one of the most congested thoroughfares in Cleveland, OH, the NEORSD elected to explore trenchless alternatives to complete the sewer run. After collaborative discussions with the DWIRS project General Contractor, Walsh-Super Excavators Joint Venture II, a plan was developed to perform the sewer installation via Hand-Mine Tunneling.
