The Aerotropolis is a once-in-a-generation opportunity to create a thriving, sustainable city.

As the Regional Stormwater Authority for the Aerotropolis, Sydney Water is responsible for delivering, managing, and maintaining the regional stormwater network on behalf of the NSW Government. Separately, we’re working to deliver drinking water, wastewater, and recycled water services.

Building stormwater infrastructure will require significant investment over the coming decades. To keep pace with development, we will build our stormwater infrastructure in stages between now and 2056.

This page provides information about the Aerotropolis Draft Integrated Stormwater Scheme Plans for Wianamatta Badgerys & Cosgroves. A third scheme for the Duncans – Mulgoa area is still in development. The schemes show a draft conceptual layout of infrastructure.
