Black & Veatch designs tunnel system for US$244mn project P lanning is underway for a 1.2 mile tunnel system, pump station and enhanced high-rate treatment facility in Cincinnati, Ohio, that could reduce the mixture of sewage and stormwater that enters local waterways.
Black & Veatch is designing the Lower Mill Creek Tunnel that could be a part of the Metropolitan Sewer District of Greater Cincinnati's Project Groundwork, a multiyear public works programme that will reduce combined sewer overflows by 85% and eliminate all sanitary sewer overflows. The Metropolitan Sewer District is also exploring alternatives or supplements to the tunnel, such as source control solutions, stormwater detention basins, rain gardens and stream separations.
