Transport facilities such as airports, transit terminals and stabling yards typically have large demands for non-potable water in the cleaning of vehicles and facilities, cooling of indoor areas and the servicing of large crowds. These facilities also often contain large roof and hardstand areas suitable for roofwater and stormwater harvesting.

High water uses suitable for alternative water supply at transport facilities include:

 Plant and vehicle wash;

De-rubberisation of trafficable pavement (eg. airport tarmac);

Cooling tower make-up water;

Workshop washdown;

Landscape irrigation; and

Toilet flushing.
