Mr Barber, who is the Zone Commander Western Plains FRNSW, said it's very much "business as usual" for towns such as Narromine.

"We're very conscious of not using the water, but no one should be worried at all that we're going to stand around and watch a house burn, because we don't want to use water, that's just not a thing," he said.

The commander said a 45000-litre water tanker has been placed in Warren to ensure the town has enough water to fight fires, and have "innovative apparatus" based in Dubbo at their disposal to fight building and bush fires in Narromine.

"We have state of the art Compressed Air Foam Tanker at the Delroy fire station, which is used now for bigger house fires," he said.

"If a shop or factory is alight in Narromine ... there is the air tanker which comes across from Dubbo which uses about a tenth of amount of water which you would normally use to create firefighting foam.

"It's just a magnificent piece of gear for our current water shortages."

Commander Barber said people in Narromine should not be worried that blazes would not be fought because of water conservation methods.

He said the brigades close relationship with the Narromine Rural Fire Service also ensures that fires will be under control.

"It's very much business as usual in town, so in Narromine at the moment they work very closely with the RFS," he said.

"The RFS have got a tanker in town which takes 9000 litres of water and if we get any house fire in town ... we would have them there to come along and help as well."

Commander Barber said firefighters don't necessarily have to use hoses and water to put out fires.

"Firefighters understand there is a drought and a water shortage, but people can rest assured we have ways and means that allow us to put out fires using very little water," he said.

"For example, we do work with the Rural Fire Service to fight bush fires, and we often use very old school ways of getting them under control.

"We still put them out, we used to use water to spray them and make sure they were completely blackened out, so there were no sparks, now we put out the perimeter of a bush fire and then we use more labour intensive methods for the rest.

"So instead of putting them out in an hour, we might have crews there for six hours, but once again we will use less water."

"It's going to be more labour intensive and time consuming, but it's just going to mean the water is going to stay where it needs to stay and isn't used on a fire."

Commander Barber said while towns such as Warren are struggling to find firefighters, towns such as Narromine and Nyngan are well staffed and resourced.
