Both detention and retention ponds require ...Retention basins – or retention ponds are often referred to as a “wet ponds”, a “wet detention basin” or “stormwater management pond”. Moreover, retention basins are used to manage stormwater runoff which helps to prevent flooding, downstream erosion, and improve water quality that’s flowing from the basin to an adjacent river, stream, or lake.A dry detention basin is an impoundment or excavated basin for the short-term detention of stormwater runoff from a completed development that allows a controlled release from the structure at downstream, pre-development flow rates. Conventional dry detention basins typically control peak runoff for 2-year and 10-year 24-hour storms.
