Book Description
The purpose of this project was to demonstrate and evaluate the feasibility of an underground void space storage tank, in containing and regulating storm overflows from a combined sewer thus reducing the pollution loads discharged to the receiving water body. System design, construction, and two years operation were conducted under the study. The prototype facility was constructed in Akron, Ohio with a combined sewer drainage area of 76.3 hectare (188.5 acres). The tank is of an excavated hopper shape, lined with an impermeable membrane and filled with an inert media. Storage of the waste water is in the void space of the media. After the storm event, the stored stormwater was gravity fed into the interceptor sewer for subsequent treatment. The underground facility was a dual usage concept. In addition to collecting, chlorinating, and detaining potential combined sewer overflows, the facility's top surface could be made usable as a park or recreational grounds.
