About the Project
The Kings Run Project focuses on removing stormwater from the combined sewer system to reduce combined sewer overflows (CSOs) into the Kings Run stream and the Mill Creek.
This federally mandated project, part of MSD’s solution for the Mill Creek, began in November 2017 and should be completed by 2019. The project will eliminate an estimated 98 million gallons of CSOs into the Mill Creek each year.
The Kings Run Project will:
- Control more than 90% of the combined sewer flows into the Kings Run stream and the Mill Creek.
- Restore Kings Run as a tributary of the Mill Creek.
- Improve the water quality of the two streams.
The project includes five phases:
- Phase A: Construction of three new stormwater detention basins and modification of a fourth existing basin in the upper part of the watershed has been completed. The basins capture and hold stormwater during rainstorms and slowly release the water back into the combined sewer system.
- Phase A-2: Construction of new storm sewers, new sanitary sewers, and relocated combined sewers along Kings Run Drive and Winton Ridge Lane has been completed.
- Phase A-3: Construction of relocated combined sewer along Kings Run Drive has been completed.
- Phase B: Construction is still underway for a 0.67 million gallon underground storage system (pipe array) at CSO 217 and stream stabilization to control erosion along the Kings Run stream, including rock and log riffles, rock armoring, and planting of native trees and shrubs.
- Phase C: Construction of new storm and sanitary sewers along Winton Road has been completed. The new storm sewer in the northern reach of Winton Road discharges into the Kings Run stream. The new storm sewer in the southern reach of Winton Road discharges into the Mill Creek.
