Thirsty Duck BFD's minimize flood attenuation volume, leaving a greater portion of the total volume available for pollution abatement in dry systems. For wet systems, the control elevation can be raised to increase residence time. Where dry pre-treatment is used to achieve required removal efficiency, Thirsty Duck BFD's make the perfect flow splitter, as they achieve constant discharge regardless of headwater depth. The Thirsty Duck TD Series also make ideal floating pump intakes for stormwater recycling systems.
Thirsty Duck BFD's were used to triple the water quality volume in a pond in Pasco County, Florida. By raising the minimum discharge elevation, an additional inch of total runoff was retained, while the increased efficiency of a Thirsty Duck BFD also lowered peak stages in the pond.
