Named APWA's 2019 Project of the Year

Cornerstone Engineering was recognized as the American Public Works Association, Kentucky Chapter’s Project of the Year in 2019.

This project was the Clifton Heights Combined Sewer Overflow Project. Louisville MSD's Clifton Heights Wet Weather Flow Storage and Pumping Facilities are a key part of the utility company's program to control sewer overflows and improve water quality in Louisville and Jefferson County.

Clifton Heights Combined Sewer Overflow Project:

The Clifton Heights CSO basin is a below-grade, cast-in-place concrete tank approaching the size of a football field. It’s filled by gravity and emptied by pumping. The basin holds 7.0 MG of CSO water when the basin is full to a depth of 26 feet and empties at a maximum pumping rate of 9.0 MGD. A single-sided basin wall forming method was used in lieu of a double-sided forming method. This resulted in reduced blasting, excavation, rock removal, and concrete wall reinforcement requirements while saving Louisville MSD approximately $2 million.
