The US$66m Dugway West Interceptor Relief Sewer is a connecting facility for almost all of the combined sewer overflow control projects in the Northeast Ohio Regional Sewer District's easterly service area. When complete, it will provide flow management to reduce the frequency and volume of overflows in the Dugway area and eliminate or consolidate several regulators to ease operation and maintenance.
Under the contract, Aecom will provide preliminary and detailed design and construction management services. The project includes construction of approximately 3,230m of main-line relief sewer, 1,220m of connecting sewers and modification of more than 40 existing system regulators. It requires large diameter shallow rock tunneling, microtunneling and open-cut construction in a tight, congested urban area.
"Aecom is excited to play a major role in this important project, which will improve the water quality and reduce flooding in the area," said Aecom president and chief executive officer John Dionisio.
The project is slated for completion in 2016.
