Welcome
Thirsty Duck Buoyant Flow Control Devices (BFD's) minimize detention storage volume by maximizing outflow rate. Depending on system hydrology and hydraulics, storage volume can be reduced up to 50%. In flood prone areas, Thirsty Duck can utilize excess system volume to provide additional flood attenuation. In environmentally sensitive areas, Thirsty Duck can utilize excess system volume for additional pollution abatement.
