Retention pond vs detention pond.
Retention vs. Detention: What’s the Difference? A common method for managing stormwater is to build a pond, or basin. There are two different kinds: retention and detention.

As stormwater flows through the wetland, it removesBenefits of Detention Ponds. Inexpensive. Take up less space. Often completely dry between storms. Detention basins are an inexpensive solution to stormwater management. They often require less space than wet retention basins. Dry detention ponds use only a very gentle slope and often have plant life surrounding them to provide …
The presence or absence of a permanent water pool, or pond, is the major distinction between a detention basin and a retention basin. Specifically, a low flow orifice regulates the water level.
