Up to 100 locals are expected to protest at the Mandurah council chambers on Tuesday night in a final effort to stop a proposal to reinstate a liquid waste facility at Tim's Thicket.
The proposal will be on the agenda at the City council meeting to seek a decision on whether the project should proceed to the next step, which includes a 28 day community engagement process.
If approved, the waste facility would provide an interim solution for the disposal of waste within the City while the Water Corporation WA consider modification to an existing waste water treatment plant in Mandurah, which could accommodate the receival of waste.
Bouvard Coast Care group members, who mobilised an ongoing campaign to reject the plan, have previously raised concerns about contaminated waste leaking into nearby waterways due to the Tim's Thicket site, which last operated in 2014.
The two biggest risk issues to the liners in the original waste facility was desludging activities and animals accessing the ponds.
However, the Environmental Protection Agency (EPA) considered it unlikely the proposal would have a significant impact on flora and vegetation, and the impacts to this factor were manageable.
According to council reports, the new facility has been designed to meet current environmental standards and includes a number of additional engineering controls to provide additional protection to the environment.
In a report prepared for council to consider this week, City of Mandurah officers recommended that council consider two options.
Council were recommended to vote to defer proceeding with a 28 day community engagement process to enable a response from the Water Corporation to be received or vote not to proceed with the proposal to upgrade the Tim's Thicket Liquid Waste Facility.
The Bouvard Coast Care Group are set to protest in the hopes councillors will vote to not proceed with the upgrades.
More to come.
