Stormwater Detention

Underground stormwater detention systems are a structural Best Management Practice (BMP) used to control the flow of stormwater. Detention systems work as an integral part of the storm sewer system to provide a temporary storage area for excess stormwater. Runoff is stored and discharged over time whenever runoff inflow exceeds the allowable discharge rate. The systems are typically installed beneath parking lots, streets and parks to maximize property usage and lower development costs. We offer a variety of materials and flexible options to meet your detention needs. (Above: CMP Detention, Kauffman Center for the Performing Arts, Kansas City, Missouri)
