The sewage concerns will be raised by Mayor Peta Pinson at this month's ordinary council meeting on February 17.

The upcoming council meeting will request the council chief executive respond to correspondence from Bonny Hills Progress Association, provide a report to council detailing the issues raised and options available to address these issues.

A community meeting was attended by Bonny Hills and Lake Cathie residents last month to raise concerns about an alleged sewage spill from the Bonny Hills Wastewater Treatment Plant into Duchess Creek and Rainbow Beach on January 8.

Due to heavy rainfall in January, Port Macquarie-Hastings Council with approval by the EPA, released treated wastewater from the Bonny Hills/Lake Cathie Wastewater Treatment Plant into Duchess Creek which flowed directly on to Rainbow Beach.

Meeting chairman John Drinan, secretary of the Bonny Hills Progress Association, said the association has sent the resolution of the meeting to council.

"(The resolution) expresses the community's strongest concern about the likely health hazards for beach users caused by discharges from the wastewater treatment plant," he said.

"(The community concerns) associated with sewage infrastructure during recent heavy rains, and the reputational damage caused to Bonny Hills and local businesses dependent on tourism.

"The council has been asked for urgent advice about the actions that can be taken to prevent these hazards in future, given increasing population pressures and the likelihood of increased frequency of extreme weather events.

"The progress association has frequently corresponded with council about these and related matters. Now it has set up a special group to investigate further and monitor action.

"These problems would not be acceptable in Port Macquarie. They have been fixed elsewhere so they must be fixable here".

Residents claim the January event is not a one-off with sewage allegedly spilling on to Rainbow Beach on Boxing Day in 2017.

Bonny Hills resident Steve Bryson, who convened the meeting, said residents are looking forward to a prompt response from council to all issues raised at the meeting.

"The community will trust council to recognise how strongly our community feels and that action is required to safeguard and preserve our beautiful Rainbow Beach," Mr Bryson said.

"We urge council to act quickly to elevate the priority of fixing the ongoing sewage and stormwater problems.

"If this was to happen at Town Beach there would be immediate action and response."

The Port Macquarie-Hastings Council was contacted for comment.
