Detention vs retention pond.

What is a Detention Pond? The main difference between a detention and a retention pond is whether or not it has a permanent pool of water. A detention pond is designed as a ^dry pond. Its purpose is to hold back flood waters and slowly release the water so that creeks and rivers do not become flooded. Are the ity of uda’s Retention ...Feb 17, 2021 · Benefits 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 extra protection. Detention involves the capture, attenuation and controlled release of stormwater volumes before they discharge to receiving environments. This moderates peak flows, reduces runoff velocities allowing contaminants to settle, and increases contact time between vegetation, soil and water. There are limitations to relying on detention as a singular ... A retention basin, sometimes called a retention pond, wet detention basin, or storm water management pond (SWMP), is an artificial pond with vegetation around the perimeter and a permanent pool of water in its design.

Detention ponds (dry ponds) and retention ponds (wet ponds) are two different types of water management ponds. In summary, both ponds aid in flood control and stormwater runoff treatment. They collect excess water and hold it for a period of time to help control erosion and water quality.Detention vs. Retention. 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.1.
