Many areas of the country have sewage collection systems that collect and transport both wastewater and stormwater to a local wastewater treatment center where it is treated before discharge.
However, during high intensity events the amount of stormwater entering the system can exceed the capacity of the treatment plant, resulting in the release of untreated flows and causing serious water pollution.
Many municipalities are correcting this by installing combined sewer overflow systems (CSO). These systems store the excess waste water and stormwater and hold it until it can be treated, thus eliminating the discharge of untreated flows.
This was the situation in Hebron, KY, where engineers from HDR Engineers were searching for a water tight, underground storage tank solution to hold the CSO.
The solution was a unique product called DuroMaxx® provided by Contech Engineered Solutions. DuroMaxx is a steel reinforced polyethylene (SRPE) pipe that provides a long service life with the capability of deep depths. The steel is wound into the polyethylene so that no steel is exposed on the inside nor the soil side of the pipe. The adaptation of these materials provides the strength of steel with the durability of plastic. Depth is even attainable with large diameters, such as the 10’ diameter pipe used for this application that provides 86,043 gallons of storage.
CSO applications requires water tight specifications, as it could be harmful to the environment if any of the wastewater was to escape. For this reason, Contech offers a watertight internal welded coupler with required DuroMaxx projects.
