Sydney Water 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

- 7 kilometres of a new wastewater pressure main
- 9 kilometres of trunk wastewater mains
- 7 kilometres of wastewater lead-ins
- 6 kilometres of trunk water mains along Kelly Street, Tenth Avenue and Edmondson Avenue
- maintenance holes and vent shafts
Quickway were engaged to perform early enabling works which included Hardstands, Laydown areas, Access Roads, and Temporary culverts for Sydney Water.
Quickway were also contracted to undertake excavation works for deep shafts (launch and receive holes) to enable the Micro tunnelling contractors to complete the tunnelling works between the Sewer Maintenance Holes. Excavation works of the shafts were on average 7m long, 5m wide and approximately 8.5m deep.
Upon Completion of the micro-tunnelling works Quickway installed prefabricated GRP Manholes/connections along the main carrier. As well as the installation of precast components. In addition to the manholes, Quickway also installed vent shafts approximately 14m high.
