Sedimentation basins are stormwater detention systems that promote settling of sediments through the. reduction of flow velocities and temporary detention. Key elements include purpose designed inlet and outlet. structures, settling pond, and high flow, overflow structures. The storage volume consists of two.
The retention volume in a dry pond is recovered using infiltration allowing soil microbes to consume pollutants. Functioning this way, a detention pond is sometimes known as dry retention. Similarly, the difference between the maximum elevation and the permanent pool is the detention volume. In this way, a wet pond may be known as a wet detention pond. Stormwater facilities are a critical part of protecting our rivers, lakes, and streams from erosion and pollutants from construction and development activities.
