The brigade was in need of a new tanker with the other one out of date and commission.

Brigade captain David Harbour said this tanker would be owned by the brigade, supporting its other tanker owned by the CFA.

"When our big tanker gets called to emergencies interstate or in Victoria, it will allow us to have our own vehicle here protecting our own area," Captain Harbour said.

Worth about $350,000 it was funded by the state government, the Country Fire Authority as well as from funds raised by the brigade itself.

Mt Buninyong covers one of the biggest areas in district 15, spanning over Lal Lal, Yendon, Scotsburn, Clarendon and Navigators.

He said it was a state of the art vehicle with extra bells and whistles to keep crew as protected as possible.

The tanker was the 100th made by Ballarat manufacturer SEM Fire and Rescue.

Vehicle sales manager Jon Julian said the company sent tankers and other fire equipment all around the state, but thought it was appropriate for their 100th to go to a brigade in the region.

They celebrated with the brigade with cake to mark the occasion.

"It takes about two months to build one from scratch," Mr Julian said.

"The cab chassis gets delivered and then we build everything around that."

Mr Julian said it was a huge milestone for the manufacturer to make their 100th tanker.

He said it was a tough time in the manufacturing industry, but the organisation tried to be innovative, invest and think of the future to ensure their success.
