Kings Run Project
The Kings Run sub-watershed is about 1,000 acres in size and includes portions of the Cincinnati neighborhoods of College Hill, Spring Grove Village and Winton Hills. The watershed was named after the Kings Run stream, which used to flow into the Mill Creek, but now discharges into a large combined sewer that collects sanitary sewage and stormwater from the watershed. During dry weather, the flows are treated at the Mill Creek Wastewater Treatment plant in Lower Price Hill. During rains, the sewer system can overflow at CSO 217 into the Kings Run stream and at CSO 483 into the Mill Creek. Every year, about 270 million gallons of raw sewage – mixed with stormwater and natural drainage – overflow into the Mill Creek.
