Conventional dry detention basins do not provide a permanent pool and are not recommended for general application use to meet water quality criteria, as they fail to demonstrate an ability to meet the majority of the water quality goals. In addition, dry detention basins are prone to clogging and resuspension of previously settled solids and require a higher frequency of maintenance than wet ponds if used for untreated stormwater flows. These facilities can be used in combination with appropriate water quality controls to provide channel protection, and overbank and extreme flood storage.

***Check out Georgia Stormwater Manual Volume 2 for structural controls for Water Quality.
Detention Structures are not recommended for water quality unless they are Extended Detention or has a Micro Pool. Detention structures can be used in Treat-Train but not as the only Water Quality Device. We do not allow small orifices in detention basins for water quality.
