Begun in 2013 and completed in 2021, the Lick Run Project in the Cincinnati neighborhood of South Fairmount is a "green" wet weather project that focuses on reducing combined sewer overflows (CSOs) into the Mill Creek, a tributary of the Ohio River.
The project uses a combination of green infrastructure, dedicated storm sewers, and real-time controls to eliminate about 800 million gallons1 annually of CSOs into the creek from CSO outfall #5.
The project captures about 500 million gallons of stormwater runoff annually from about 65% of the 2,900-acre Lick Run Watershed and conveys it directly to the Mill Creek through the Lick Run Greenway, a bioengineered surface stream. During heavy storms, excess stormwater can also be conveyed directly to the Mill Creek through a large underground storm sewer conveyance box.
The Lick Run project was designed and constructed as 12 separate projects. Four of the 12 projects are green infrastructure including the bioengineered surface stream, stream restoration, bioswales, and stormwater detention basins. The remaining eight projects are storm sewers. For more information, please see the Project Map.
