The U.S. EPA has approved the Metropolitan Sewer District of Greater Cincinnati’s (MSD) remedy for removing 1.78 billion gallons of combined sewer overflows (CSOs) annually from the Mill Creek.
This Lower Mill Creek solution – officially approved on May 30, 2013 – will be implemented in place of a deep, underground storage tunnel. All projects must be constructed by 2018, during Phase 1 of Project Groundwork, MSD’s Consent Decree program.
This sustainable remedy will not only improve water quality but will serve as a catalyst to improve local neighborhoods and create new jobs. It focuses on reducing the amount of stormwater in MSD’s combined sewer system through the use of stormwater detention basins, new storm sewers, and restoration or daylighting of stormwater and natural drainage flows, among other projects.
The total cost is estimated at $244 million (in 2006 dollars), which is about $200 million less expensive for ratepayers than the deep tunnel.
The remedy includes projects in the Lick Run, Kings Run, West Fork and Bloody Run watersheds.
