2 Water Tanker Fire Appliances Water tankers carry approximately 8,000 litres of water to an operational incident, invariably to large or remote fires. This water can then be dumped into a dam at the incident location while the water tanker goes to refill, or the water tanker can remain on site at the incident and feed water directly to a Class B or Aerial fire appliance. Water tankers also have spray bars that allow oil detergent sprayed at high pressure to safely wash oil spills from roadways, without the requirement to unnecessarily deploy fire-fighting personnel onto live roadways. Fire service water tankers have also been used extensively over many years to assist with community resilience, particularly in times of severe weather. Fire service water tankers have provided water to vulnerable communities, local businesses and hospitals amongst others during periods of cold weather and droughts. The availability of large volumes of water is a fundamental requirement for fire-fighting operations. Water availability is not always guaranteed as seen recently during major storms. In these circumstances, water tankers provide crucial logistical support for fire-fighting operations.
