Austral Leppington Wastewater Stage 3
Sydney Water, alongside the Department of Planning and Environment, Councils and other utility providers are planning and building the Austral Leppington Wastewater Stage 3 project. The project will provide safe and reliable drinking water and wastewater to service growth in the Austral and Leppington precincts.
The project includes the construction and operation of:
• new wastewater pumping station along Gurner Avenue
• permanent access road within the pumping station
• 1.7 kilometres of a new wastewater pressure main
• 6.9 kilometres of trunk wastewater mains
• 1.7 kilometres of wastewater lead-ins
• 3.6 kilometres of trunk water mains along Kelly Street, Tenth Avenue and Edmondson Avenue
• maintenance holes and vent shafts
Our delivery partner, the West Region Delivery Team, has commenced construction of Stage 3 Phase 1. Phase 1 is an interim delivery solution providing wastewater infrastructure to service up to 1,700 lots located at Austral and Leppington.
Phase 2 servicing is linked with the construction of the Upper South Creek Advanced Water Recycling Centre, due for completion in 2026. Final wastewater infrastructure for the entire catchment is expected to be in place from the end of 2026, with ultimate servicing of 37,000 dwellings expected by 2056.

FAQs
- Is the projected delayed?
- Why has the project timeline changed?
- How do I know if my property is part of the 1,700 lots capacity?
- Has construction work commenced and when will it be completed?
- Sydney Water has revised its policy for the Bonding of Works (Section 73 Certificates) for Austral. What does this mean?
- What are the next steps?
-
Developer Forum Q&As
- What is the forecast date for completion of the 1,700 lot works, net of contingency and what is the duration of contingency allowance?
- Who will undertake the pump out in Scenario 1?
- Can you provide an update on the key infrastructure in Upper South Creek - is it currently on schedule for 2026?
- Can we get the Section 73 certificate in October 2022 if construction is already completed?
- Can Sydney water provide regular updates on the 1,700 lot package of infrastructure works to help us all plan our works?
- Will Sydney Water provide a guideline for the pre-occupy IOP and their requirements for monitoring and control?
- Can developers group together to create a shared localised IOP?
- Do you have number of minimum lots for an IOP to be approved?
- Will more servicing be provided for the Phase 1 Catchment outside of 1700 lots prior 2025?
- When will Austral stage 3 be fully serviced?
- Can developers share the tankering company details for active IOP pumpouts? This will allow for optimisation of the same tanker to be able to service multiple IOPs.
- Even if developers undertake an IOP, they won’t get their application approved nor constructed by June 2023, making it not worth the effort for 26-30 lot sites. Therefore, can Section 73 certificates be issued 12 months instead six months?
- Will Sydney Water provide guidelines on the Pre-occupy IOP with requirements and monitoring systems?
- Is the December 2023 forecast completion for the proposed pump station, or for the horizontal carriers?
- Is Sydney Water fully committed to the revised Section 73 certificate release date of June 2023?
