Can CSO Basins Accept More Flow Without Constructing Additional Capacity?
Abstract:CSO detention basin that have been designed with conservative hydrologic assumptions, but may be capable of accepting additional flows while meeting disinfection requirements with shorter contact times. After constructing a 3.1 million gallon (MG) combined sewer overflow (CSO) basin as part of the Rouge River National Wet Weather Demonstration Project, the City of Inkster began seeking solutions to control CSO from their remaining uncontrolled CSO outfalls. They turned to available capacity in their existing basin identified during the basin's two and half year performance evaluation period. A special performance study was undertaken to determine if the facility was able to achieve the required degree of disinfection under conditions of decreased contact time.
This paper will present the results of a sampling program designed to test the ability of the Inkster CSO Basin to achieve adequate disinfection through a 20-minute contact time. The results are being used to support the selection of a CSO control alternative that will allow the Inkster Basin to accept and treat flows from a larger tributary area. The potential cost savings of using this approach is nearly 12 million or 30,000 per acre.
