February 1, 2024 Yard Focus. What is a Detention Pond? Have you ever wondered what is a detention pond and what is it's purpose? Heavy rain can turn your backyard into a swamp and threaten your basement with flooding. A detention pond is a smart solution that captures stormwater runoff before it causes chaos. A retention pond is a permanent pool of water that is designed to improve water quality by treating storm water runoff. Retention ponds are designed to hold rain water that has runoff from the surrounding lawns, roads, parking lots, and roof tops (“Storm water detention,” 1998). Since the 1970s, stormwater detention has been widely accepted as an effective means to reduce the developed peak flow to its historical rate. A detention basin is often designed as a regional flood control facility to reduce the 10- and 100-year runoff releases. Figure 1. Detention Basin Click here to enlarge image.May 22, 2022 · A detention pond is surrounded by a vegetative buffer that can withstand both wet and dry conditions. A detention pond can cost less to implement than a retention pond because they are generally smaller (even if the range for depth is larger) Disadvantages.

Heavy rain can turn your backyard into a swamp and threaten your basement with flooding. A detention pond is a smart solution that captures stormwater runoff before it causes chaos.Detention Pond vs Retention Pond. Detention Pond releases water into the drainage system. Retention Pond does not release to a downstream system. Detention pond also refers to dry basins. However, Retention Ponds refer to wet basins. Detention ponds are designed to hold water by the process of underground pipes.

Retention ponds have flow orifices above the pond’s bottom. Operators place the flow orifice at the desired depth level when flooding is not occurring. Similarly, to how detention ponds work, when water levels in a retention pond are higher than the flow orifice, water flows out until the pond reaches its normal level. Dec 18, 2023 · Learn the differences between detention and retention ponds, two methods of managing stormwater runoff.
