If you have a helipad on an occupied building you will likely need a Fuel Water Separator to comply with NFPA and International standards. Containment of all runoff on the helipad is required and FEC Heliports manufactures a single tank design that makes for a simple solution. Our standard Fuel Water Separator is a gravity fed design that is connected to a helipad containment gutter. The tank has two sides, one for separation (400 gallons water) and one for containment (300 gallons) and includes a heater and a high level indicator. This welded steel design has a protective coating for the harshest environments and has a single input and output for inexpensive hook up by the mechanical contractors.
