For Orange's street cleaning crew, sweeping hundreds of tonnes of fallen leaves from streets signals the season changing, with one crew from Orange City Council and another from Wangarang Industries to join last in the season.

Mayor Reg Kidd said despite being the backdrop for some of Orange's major events, "all those leaves will be on the ground" soon.

"As anyone who spends time raking fallen leaves in their yard knows, it can be an endless task, but what if you had to shift leaves from hundreds of kilometres of local streets?"

He said it was a huge effort for the crews, who use a fine misting, high-pressure water spray to blast leaves out of the gutters before putting them on a truck.

Cr Kidd saying the spray setting uses "hardly any water", all of which comes from council rainwater tanks, and is essential to stop leaf dust from being hazardous to residents' or crews' health.

"They use a high-pressure water spray to blast the piles of fallen leaves from footpaths and out of neighbourhood gutters out onto the edge of the road," he said.

"They then use a giant truck-mounted vacuum to pick up the dampened leaves and carry them away.

"The tonnes of leaves are added to the city's green waste to be made into compost."
