FOLLOWING repeated complaints about the foul stench from the public toilets on the Airlie Beach foreshore, Whitsunday Regional Council are claiming they've finally fixed the problem.

This week, council began a magnesium hydroxide dosing trial, which they say has stopped the odour coming from the Coconut Grove sewage pumping station at the toilets.

Mayor Andrew Wilcox said they had been regularly checking the toilets since Monday and he believed the smell was gone.

"There's definitely been an improvement, I think the guys have done a really job," he said.

"So far we see the odour is not apparent.

"Council staff have regularly visited the problem odour locations around Airlie Beach this week, including the Coconut Grove pumping station opposite Airlie Beach Hotel, and have found no noticeable odour problems at vent poles or air valve pit locations."

Market goers and passers by have long complained about a lingering odour coming from the public toilets and Cr Wilcox said any further problems would be sorted out by the engineering department.

"Council is about constant improvement," he said.

"This has been identified as a problem site.

"Our engineers, have been working hard and they've come up with a very good solution."

The program is expected to continue over the next month and Cr Willcox said council would permanently implement the programme should it continue to work.
