Here’s a look at why retention and detention pond maintenance is crucial. 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. Retention ponds are pools of water that fluctuate in response to rain and runoff. They may look like regular ponds, but if you look a little bit closer, you can usually tell the difference between a retention pond and a regular pond.

A retention tank usually refers to a tank that is meant to be filled with stormwater so that it can be used for a different purpose at a later time. Detention tanks, on the other hand, are used to meter the flow of stormwater back into the soil or additional drainage systems which eventually lead back to a local sewer. The intent of this arrangement is generally to store all the inflow until the pond level reaches the weir or other overflow device. Any excess volume will flow over the weir and continue downstream. As the inflow subsides, the storage may be emptied by exfiltration, and/or a low-flow outlet device. To avoid the complexity of using two ponds ...Dry detention pond: a pond that will normally not have standing water, except for a short time after a large storm event.
