Your guide
We've developed a summary document that explains the different elements of the Aerotropolis Integrated Stormwater Scheme.
If you'd like to know more about our plans and what they might mean for you, this is a great place to start.
The Aerotropolis is a once-in-a-generation opportunity to create a thriving, sustainable city. As the Regional Stormwater Authority, we’re committed to supporting the delivery of regional stormwater infrastructure to service the Aerotropolis.

Listening to your feedback
In 2025, we released the draft Integrated Stormwater Scheme plans for Wianamatta Badgerys, Cosgroves and Duncans Mulgoa catchments. Thank you to everyone who shared feedback on the draft Integrated Stormwater Scheme Plans. We received more than 100 submissions from private landowners, developers and other stakeholder groups.
Your feedback has helped shape the Final Integrated Stormwater Scheme Plan, refine infrastructure sizing and locations and ensure all technical, environmental and regulatory requirements are met.
