Work has started on the remediation of the old Mullumbimby Sewage Treatment Plant (STP).
The STP was built in the 1970s to treat the wastewater from Mullumbimby and was decommissioned in 2011 with the opening of the new Brunswick Valley STP at Vallances Road.
In keeping with NSW Government legislation Council has started remediating the old STP to meet the requirements of the NSW Contaminated Land Management Act and Regulation.
- Demolishing infrastructure
- Excavating, stockpiling and removing contaminated soil
- Sampling and validating the remediated site
The recycled effluent pond and associated infrastructure will be retained on the site as they remain operational as part of the Main Arm recycled water scheme where water is treated and reused for irrigating pastures.
The remediation project will be completed in April 2021.
Council has not yet decided on the future use of the Mullumbimby STP site.
