LOGAN councillor Phil Pidgeon expects a political backlash once the preferred site of a waste water treatment plan is made public next month.
The council's preferred sewage treatment plant, known as site B, would service the growing development corridor from Park Ridge to Yarrabilba to ease pressure on the Loganholme plant which is close to capacity.
Water committee chair Cr Pidgeon told a Logan Country Safe City meeting he received a confidential briefing on the preferred site which would directly affect landowners in the division he represented.
The final decision came down to two potential sites, both affecting multiple land owners.
"I am aware of the preferred site but I'm not allowed to tell you," he said. "In my personal view the site that has been recommended is not the one I support.
"As soon as the site is made public there will be some community politics involved and there will be some upset people. The preferred sites are in my electorate.
"In a nutshell, it will not be a popular decision and I'm right in the middle of it. I'm damned either way.
"I don't believe every councillor will vote for that decision to be honest. I may be one of those but a decision will be made."
Cr Pidgeon said the process had been delayed following state government advice on buffer zones.
"In light of the advanced technology used for the waste water treatment plant, the state government advised council the buffer zone of 550 metres would not be needed and we could scale back the buffer area," he said.
"The advice was provided during the course of investigations which triggered council officers to reassess all sites that had previously been put up.
"Council has been extra thorough as a third site came back into the equation and they had to take that into consideration to see if it crossed the line or not."
Controversy over potential sites reached fever pitch last year when Stockleigh property owner Margaret Hawkins said her 60.7 hectare farm would be chosen.
Ms Hawkins launched a petition to save her property.
Cr Pidgeon later said there were better options for the sewage treatment plant.
Logan City Council will release reports and analysis underpinning the decision once the preferred site is revealed.
