. Transfer point
The water transfer points between the airport source and the aircraft onboard storage and
distribution system present significant opportunities for contamination. Common equipment
used to transfer water includes (but is not limited to) piping, hoses, potable water cabinets,
bowsers, tanks, filling stations, refillable urns and jugs, and hydrants (including taps/faucets).
Equipment should be constructed of appropriate materials (e.g. corrosion-resistant materials)
certified for this application, properly designed, operated, labelled and maintained, and used
for no other purpose that might adversely affect the quality of the water. Assumptions and
manufacturer specifications for each piece of equipment need to be validated to ensure that
the equipment is effective.
