Florida DOT selects buoyant flow control device for its projects

The Florida Department of Transportation (FDOT) has recently approved the Thirsty Duck Early Riser 200, a buoyant flow control device, for use on production projects.

The product was successfully tested for hydraulic performance and debris tolerance at St. Anthony Falls Laboratory in Minnesota, which provided the impetus for the FDOT using it in its storm water management facility.

The device allows for a constant discharge of water out of a storm water management facility. With the ability to obtain a constant discharge, storm water storage volume within a pond may be reduced, thus allowing for cost savings on right-of-way acquisitions.

The product is expected to improve pond efficiency with respect to pond volume whenever the size of dry or wet retention ponds is driven by peak discharge attenuation.
