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.A detention basin is designed to detain or hold water for a specific time period, usually between 24 and 48 hours, before it is released downstream at a controlled rate. A retention basin, on the other hand, is designed to keep water on-site permanently. There are several reasons why you might need a detention tank.The main difference is the purpose of the pond. Retention ponds are designed to hold water, while detention ponds are designed to detain water and release it slowly over time. Another key difference is the depth of the pond. Retention ponds are usually shallow, while detention ponds are usually deep. Finally, retention ponds …Basins are generally used to collect stormwater and release it at a controlled rate to prevent flooding and erosion. Some basins can also filter some pollutants out of the water before it enters the storm drain system. Table 2.2.1 summarizes some common mitigation solutions that can improve the performance of these basins. Table 2.2.1.Detention ponds gradually release stormwater through an outlet structure to adjacent surface waters rather than through infiltration into the soils. Detention ponds can be designed as wet or dry. Wet detention ponds are constructed so that the pond bottom is below the SHWT elevation. Dry detention ponds set the pond bottom above the SHWT.Now there is a better way. TRUEGRID Permeable Paver parking lot installation at the North Houston Bike Park, in Houston, TX.

Conventional dry detention basins typically control peak runoff for 2-year and 10-year 24-hour storms.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.DESCRIPTION.
