Aerotropolis stormwater development requirements

Information for developers

Sydney Water is responsible for the new Western Sydney Aerotropolis precincts' major stormwater infrastructure. This integrated water system will be the largest stormwater harvesting scheme in Australia. The information on this page will help developers applying for Section 73 Compliance Certificates.

Our responsibility

The NSW Government has appointed Sydney Water as the Regional Stormwater Authority in the Western Sydney Aerotropolis precincts, including the Mamre Road Precinct. We're responsible for delivering, managing and maintaining the regional stormwater network alongside our drinking water, wastewater and recycled water networks.

We're managing the Aerotropolis precincts' drainage networks in partnership with Penrith City and Liverpool City councils, which will manage the non-trunk drainage stormwater network within the roads and streets.

Design of stormwater works

If you are constructing works required by us, your design needs to be certified before you can start work. All design work should be consistent with the draft Stormwater scheme infrastructure design guideline: Western Sydney and its appendices:

• Appendix A – Engineering drawings (1.1 MB, ZIP)
• Appendix B – Riparian corridor planting palette
• Appendix C – Engineering requirements checklist.
