A $7-million infrastructure project will address long-standing stormwater pollution at Coogee Beach.
Long-Term Issue at Coogee Beach Gets Solution
A decades-long concern over pollution at Coogee Beach is being addressed through a proposed plan to divert stormwater away from the shoreline. Local officials are investing $7 million in a project that aims to improve water quality and protect public health at the popular beach.
Historical Pollution Concerns
Stormwater contamination at Coogee Beach has been an issue for years, particularly following heavy rainfall. The current outlet, located at the northern end of the beach, discharges stormwater containing a mix of pollutants, including petrochemicals and faecal matter.
Since at least 2016, Coogee Beach has consistently received “poor” water quality ratings in the NSW Government’s Beachwatch reports. This has placed it among the lowest-rated ocean beaches in Sydney, alongside others like Bronte and Malabar.
Local surf lifesaving groups and resident organisations have long raised concerns about the health risks and the need for an infrastructure upgrade.
Project Details and Implementation
The plan includes construction of a new underground pump station and pressure mains. Stormwater will be rerouted through an existing but rarely used Sydney Water tunnel and discharged further north, away from Coogee Bay.
The new discharge point will be off Dunningham Reserve. The aim is to stop stormwater from running across the beach after rainfall, thereby improving water quality and reducing health hazards for swimmers.
The initiative will be co-funded by the NSW Government, Randwick City Council and Sydney Water. Work is scheduled to begin later this year, subject to planning and approvals.
Limited Alternatives, Clear Preference
While previous efforts included gross pollutant traps, these have not proven sufficient. Local stakeholders emphasised the need for a more permanent solution, leading to the selection of the tunnel-based diversion system as the most viable option.
Community Support and Response
Local surf lifesaving officials noted the ongoing impact of beach closures after rain, including disrupted events and health concerns for swimmers and rescuers.
Resident advocacy groups, such as Coogee Residents Against Polluting Stormwater, have welcomed the plan, having campaigned for improved water management for years.
Local representatives have described the development as a community-driven result that balances environmental, health and tourism priorities.
Next Steps
Construction is expected to begin within the year. Once complete, the system will reroute polluted stormwater away from Coogee Beach to maintain cleaner water conditions year-round.
