WIMMERA councils fear they will lose their voice when the region's waste management groups amalgamate.
The State Government has announced plans to halve the number of regional waste management groups across Victoria in the next 18 months.
The region's Grampians and Desert Fringe waste management groups will combine with the Highlands group to create a 12-council super group.
Under the proposal, Wimmera councils could lose their representation with only four positions for the 12 councils.
Environment Minister Ryan Smith will select the four councillors, who will join four skills-based members.
West Wimmera Mayor and Desert Fringe group member Bruce Meyer said the amalgamation failed to make sense.
"A lot of the issues are localised and it is going to be very difficult to handle the issues that are unique to a local area with such a big group," he said.
"If everything is going to be based in Ballarat it is another move closer to the city and further from us."
Cr Meyer fears Desert Fringe's metal recycling program will fall by the wayside when the groups combine.
He said he would not join the new group despite being a member of the Desert Fringe Regional Waste Management Group since its inception in 1997.
Northern Grampians Mayor Wayne Rice said the council would lobby to have a councillor on the new group.
"Going bigger is not always in the best interest of everybody involved," he said.
"You tend to lose your voice and the ability to have any say in it, which is never a good thing. We have had our fair share and will continue to have a fair share of problems with the Pomonal Road landfill.
"Given that the Pomonal Road landfill is in our shire, only four kilometres out of Stawell and that we actually own the hole, one would think we would have to have some say in the matter."
Horsham Rural City Council technical services director John Martin said despite representation concerns, the amalgamation could broaden the group's waste management role.
"There is a perception that we could be disadvantaged because of the representation but there could be a number of benefits as well," he said.
"Getting the right membership is going to be key to off setting the legitimate concerns.
"The three management groups are planning to meet shortly."
