retention pond (redirected from Retention basin)

retention pond

A human-made pond where storm water is directed and retained until it can be absorbed into the water table or slowly released without flooding downstream property owners. The modern trend is to prefer absorption into the natural water table,so many local governments impose retention pond requirements as a condition of development,even if storm sewer facilities are available. Many modern office park water features, such as small lakes with fountains, are government-required retention ponds.
