Delivery Update - May 2023

With no significant delays due to wet weather experienced during May, completion of the Austral Leppington Wastewater Stage 3, Phase 1 project remains on track for December 2023. Some of our key achievements for the project during May include:

• Ongoing tunnelling of wastewater pipes - Kemps Creek carrier, Austral carrier and the Bonds Creek Carrier
• Ongoing delivery, excavation and installation of critical maintenance holes
• Ongoing concreting at the Gurner Avenue pumping station

Looking forward into June, weather and ground conditions permitting, we will be focused on:

• Completing the tunnelling of the Kemps Creek and Bonds Creek carriers and lead-ins
• Ongoing installation and testing of critical maintenance holes
• Completing concreting at the Gurner Avenue pumping station and testing it before installation of the internal pumps & pipework

See below images captured by our delivery team of their progress throughout May.

The April-June 2023 quarterly update will be posted on this page during early July 2023.
