Detention vs retention pond.

The difference between a detention basin and a retention pond is the existence of a permanent pool, i.e., the former does not have a permanent pool, whereas the latter (being wet ponds) does have a permanent pool. The performance results in retention ponds are more different from the OLS results than those in detention basins.

1.3 On-site Detention and Retention Features Peak runoff reduction can be achieved through the implementation of on-site ABC Waters design features and structural detention and retention features, such as: - Detention tanks - Retention ponds/Sedimentation basins - Larger perimeter drains - Wetlands - Planter boxes - Bioretention swalesA detention basin focuses on volume control, temporarily storing stormwater and slowly releasing it to prevent overwhelming storm sewer systems. These ponds often feature outlet structures that regulate the flow rate. Retention ponds, however, aim to maintain a consistent water level, utilizing evaporation, and percolation to manage water …Table 2 presents the modeling results with the required storage volumes for attenuation of flows to the allowable release rate.
