A batch detention basin is an extended detention basin that is primarily used to remove particulate pollutants and to mimic predevelopment hydrology. Batch detention basins have superior water quality performance over traditional sedimentation/sand filters and achieve a total suspended solids (TSS) removal efficiency of 91%. The basin is designed to manage stormwater runoff by storing it and releasing it gradually until completed drained. Unlike a detention basin, a retention basin or pond is designed to permanently hold water. Retention basins are commonly used when the groundwater is near the surface of the ground. A retention basin will not have an outlet structure. The construction of a retention pond can range from USD 35,000, to USD 1,000,000 depending on the size and modifications made to the pond.
