If this is the case, clay blankets may be used to overlay or compact the existing soil and therefore make it less absorptive. Retention vs. Detention Basins. Retention basins are not to be confused with detention basins.Detention Basin Trash Racks. Maintaining proper water levels in detention basins, underground detention basins, and wet ponds is dependent on free-flowing outlet control structures (OCS). Water velocity and flow directs water to the outlet control structure where it leaves the basin at a controlled rate through an orifice or weir.

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.

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. The largest advantage of detention ponds are the cost efficiency. They are essentially large holes in the ground and can remain that way until a large storm. Similar to retention ponds, however, a large disadvantage to these ponds is that they require a lot of space to be useful.
