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.underground detention Systems. Underground detention systems, or underground ponds, are often used on new development to hold and slowly release stormwater. As new development often converts a forest canopy to impermeable asphalt and rooftop, it is not fair to push the increased runoff into existing streams, rivers and downstream neighbors.A detention dam is a dam built to catch surface runoff and stream water flow to regulate the water flow in areas below the dam. Detention dams are commonly used to reduce the damage caused by flooding or to manage the flow rate through a channel. Detention dams can also be constructed to replenish groundwater and trap sediment. Detention dams …

A detention basin is an area that has been designed and designated for the temporary or permanent retention of floodwaters during rain or flood events. Detention basins are generally designed in two forms- dry or wet basins. Dry basins retain water only during storm events, later releasing the water at a controlled rate until the basin empties.A detention basin in Sterling, Virginia, in the United States.

Retention basins, also known as “wet ponds”, are . typically used for flood control in subdivisions and on commercial properties to decrease peak flows and slowly release collected rainfall runoff over a longer period to reduce local flash flooding. Wet ponds can also be designed for “extended” storage, Water quality best management practices (BMP) help protect water quality by removing pollutants from stormwater.

Retention basins, also known as “wet ponds”, are . typically used for flood control in subdivisions and on commercial properties to decrease peak flows and slowly release collected rainfall runoff over a longer period to reduce local flash flooding. Wet ponds can also be designed for “extended” storage,1. Retention ponds are designed to hold and slowly release stormwater runoff over an extended period of time. 1. Detention ponds are designed to temporarily store stormwater runoff and release it at a controlled rate. 2. Retention ponds are typically designed to mimic natural wetlands and provide habitat for wildlife. 2. The surface area of stormwater wetlands should make up at least 1 percent of the area draining to the practice. Wetlands should have a length-to-width ratio of at least 1.5:1. Making the wetland longer than it is wide ensures that water entering the wetland receives adequate treatment. Off-line storage refers to any arrangement where the storage is placed beside the main flow path, and water is diverted into the storage volume by an adjacent control structure, such as a catch basin and weir. The intent of this arrangement is generally to store all the inflow until the pond level reaches the weir or other overflow device.Infiltration basins can be relatively cost-effective post- construction stormwater controls because their construction requires minimal infrastructure. Typical. construction costs, including contingency and design costs, can range from $55,000 to $85,000 per acre of impervious surface treated (King & Hagan, 2011).extended detention basins, retention ponds and constructed wetland ponds).
