What we've done so far
Since 2022, we have been working with landowners, government and the development industry to shape the frameworks and principles that guide how we will manage stormwater across the Aerotropolis and Mamre Road areas.
So far, in consultation with industry and stakeholders, we’ve finalised key documents that will guide development in the area, including Stormwater Scheme Principles and a Developer Works Policy.
Mamre Road Precinct integrated stormwater DSP was approved by IPART in May 2025 and is now in delivery. We also recently exhibited the draft stormwater scheme plans for Wianamatta Badgerys & Cosgroves and are now releasing the Consultation Outcomes Report from the exhibition.
We’ve now developed the draft stormwater scheme plan for Duncans Mulgoa, and we would like your feedback on this.
Next steps
Once the scheme plans for Wianamatta Badgerys, Cosgroves and Duncans Mulgoa are finalised, we’ll use them to draft Development Servicing Plans (DSPs). Draft DPSs for Wianamatta Badgerys, Cosgroves and Duncans Mulgoa are expected to be completed late 2025, exhibited in early 2026 and then finalised.
You’ll have a further opportunity to comment on these, and we’ll keep landowners and key stakeholders informed as the project progresses.

Resources
We've developed a handy list of Sydney Water and government published resources, along with a glossary that explains some of the key terms.
