CSO plans for Cincinnati
- Planning is underway for a $244 million deep tunnel CSO interceptor as part of a multi-billion, multi-year public works program designed to reduce sewer overflows into the local waterways of the city of Cincinnati, Ohio. Black & Veatch is designing the 1.2 mile (2km) Lower Mill Creek Tunnel that could be a part of the Metropolitan Sewer District of Greater Cincinnati's Project Groundwork that aims to reduce combined overflows by 85% and eliminate sanitary sewer overflows all together.
- The tunnel system with a pump station and an enhanced high-rate treatment facility would reduce combined sewage and stormwater overflows to local waterways and improve the quality of life for the more than 2 million people living in the metropolitan area.
- Alternatives or supplements to the tunnel, such as source control solutions, stormwater detention basins, rain gardens and stream separations, are also being explored by the Metropolitan Sewer District.
- "Tunnels are an inherently sustainable design method for capturing combined sewer and sanitary sewer overflows," said David Egger, Vice President and Heavy Civil Lead in Black & Veatch's global water business. "The underground option creates fewer disturbances and disruptions to the local community when compared with alternatives."
- "Tunnel design and implementation for reducing sewer overflows is a steadily growing practice at Black & Veatch," said Dan McCarthy, President and CEO of Black & Veatch's global water business. "We expect this growth to continue as more cities, both large and small, work to reduce their sewer overflows."
