International Water Association Sponsored by the Metropolitan Sewer District of Greater Cincinnati and Greater Cincinnati Water Works Cincinnati is gaining a national reputation in the sustainable management of stormwater to prevent combined sewer overflows (CSOs). Join the Metropolitan Sewer District of Greater Cincinnati (MSD) and Greater Cincinnati Water Works (GCWW) for a to learn more. The tour - from 10:30 a.m. 12:30 p.m. on Friday, April 24, 2015 will visit four different locations to view stormwater controls ranging from bioswales and level spreaders to green roofs and pervious pavement. The tour will also visit the project area for the Lick Run urban waterway. The last stop will focus on Greater Cincinnati Water Work s new ultraviolet disinfection facility for drinking water. The tour highlights include: Bioinfiltration Basins at St. Francis Court Apartments: Two bioinfiltration basins (7,000 square feet in total) that work together (upper and lower sections) constructed on the site of two unused parking lots The basins capture stormwater from a 1.3-acre forested hillside. U.S. EPA, Ohio EPA and U.S. Geological Survey maintain a weather station and flow monitors on site. Project currently results in a 360,000 gallon annual reduction in stormwater runoff that 1 P age
Bioswale at Rapid Run Park, a City of Cincinnati park 1,600 linear feet of bioswale that includes a series of step pools; landscaped with with 49 native trees, 158 shrubs and 36,000 plant plugs Two small bioretention basins and about about 1,900 linear feet of new storm sewers along Rapid Run Pike Project will result in a ~165 million gallon annual reduction in stormwater runoff (when connected to the adjacent Sunset Avenue project) Lick Run Urban Waterway Project Site Anticipated construction: Summer 2015 Summer 2018. 1.5-mile stormwater conveyance system to convey (carry) stormwater to the Mill Creek. Includes the following elements: o Wetland forebay and infiltration basins in the old Queen City Avenue area. o Headwaters area east of White Street where the urban waterway begins. o 1 mile of urban waterway, from the Headwaters area to the Pond area east of Harrison. o Improved civic recreation space between Grand and Harrison avenues. o Pond area east of Harrison Avenue. o Stormwater conveyance box underneath the entire system to handle large rainstorms. 2 P age
Various Stormwater Controls at Cincinnati State Technical and Community College Eight different kinds of sustainable stormwater controls, including 10 rain gardens totaling 56,000 square feet, infiltration chamber, 420-square-foot level spreader system, ~2,000 square feet of porous asphalt, ~1,650 square feet of porous concrete and ~40,000 square feet of permable pavers, bioretention pond, and two 10,000-gallon underground cisterns. Tour will focus on linked controls on the north side of the campus, which include rain gardens, level spreaders, and an infiltration chamber. Extensive monitoring program in place to measure effectiveness of controls Project results in a ~10 million gallon annual reduction in stormwater runoff that 3 P age
Various Demonstration-Level Stormwater Controls at Civic Garden Center Five separate 1,200-square-foot parking areas consisting of permeable pavers (two types), porous asphalt, porous concrete and traditional concrete Green roof area including intensive (deep roof), extensive (shallow roof) and green roof trays Three bioswales covering 1,500 square feet 3,000-gallon aboveground cistern Extensive monitoring program in place to measure effectiveness of controls Project currently results in a 40,000 gallon annual reduction in stormwater runoff that Ultraviolet Disinfection at Greater Cincinnati Water Works (GCWW) GCWW treats about 132 million gallons of water a day on average and conducts about 600 tests daily throughout the water treatment and distribution process. GCWW uses the most advanced water treatment technology known in the industry including sand filtration, granular activated carbon adsorption and ultraviolet disinfection (UV). GCWW is now the largest water utility in North America to use UV disinfection following sand filtration and granular activated carbon. UV disinfection has been identified by the U.S. EPA as one of the best technologies to inactivate harmful water microorganisms such as Cryptosporidium and Giardia 4 P age
