Wollondilly Shire Council is urgently seeking help from the NSW Government to resolve a significant sewer capacity shortfall in the Wilton Growth Area, jeopardizing the development of 12,000 already rezoned lots.

Sydney Water’s delays in upgrading the Bingara Gorge Sewage Treatment Plant have caused frustration, with Council criticizing the lack of coordination between state planning and infrastructure agencies.

Wollondilly’s Mayor Matt Gould expressed dismay over Sydney Water’s reversal of previous commitments, delaying housing construction crucial for addressing the housing crisis. The interim solution of trucking sewage out of the area is deemed inadequate, with no assurance for future developments in Appin.

“We are now facing a ridiculous situation where housing supply is being stopped by the lack of investment by Sydney Water,” Cr Gould said.

“Wollondilly is willing to do its fair share to address the housing crisis, through the provision of housing at Wilton, however the failure of Sydney Water to properly plan for and provide the necessary enabling infrastructure is now interfering with this.”

Wollondilly Council is demanding urgent action from the Premier and Water Minister to address the shortfall and ensure timely delivery of necessary infrastructure, including upgrades to the Bingara Gorge Treatment Plant. It advocates for infrastructure to precede development, urging the Government’s firm commitment to the Upper Nepean Advanced Water Recycling Facility by 2032.
