Water Delivery Support Unit: It's for the Big One
A 2000 GPM fixed master stream
The W.D.S. unit can obtain water from either a hydrant system or a static water source. The operation for using a static water source is not done by drafting. Instead the W.D.S.unit uses an appliance called a Turbo Draft that actually works simular to a foam eductor and educts water through it back to the pumper. The main advantage the Turbo Draft has over the standard drafting operation is that the pumper can be up to 200’ away from the water source and still get water .
