Detention basins are often used in storm water management systems to reduce peak flows. Often, regulatory authorities require that any land-use changes must be accompanied by measures that ensure that the peak discharge from a design storm after land-use changes will not exceed the peak discharge for the same event prior to the changes. Often this …This video describes how to perform routine maintenance on stormwater extended detention basins, a common type of stormwater best management practice (BMP). ...This video describes how to perform routine maintenance on stormwater extended detention basins, a common type of stormwater best management practice (BMP). ...Retention Basin vs Detention Basin: Stormwater Management There is no denying the fact that effective stormwater management is…

An extended detention basin can also be designed to provide Full Spectrum Detention. In this case, the EDB is sized for 100-year peak reduction and the excess urban runoff volume (EURV) is used instead of the WQCV. The EURV is designed with a drain time of approximately 72 hours. Widespread use of Full Spectrum …Thus, the influent flow rate is the rate at which new wastewater enters the aeration tank, and since the tank is of a specific size, the rate at which the influent enters is also the rate at which effluent exits. So, for accurate HRT calculation, use the hydraulic retention time formula “HRT = V/Q.”. Here, you are dividing the volume of the ...What is a detention basin? A stormwater detention basin (or pond) is used to collect and temporarily store stormwater, while releasing a lesser amount with the intent of lowering the risk of flooding downstream. Detention is not to be confused with retention, which is used by some jurisdictions and retain stormwater indefinitely.
