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.
