Delivery Update - July 2023

July was a productive month for the Austral Leppington Wastewater Stage 3, Phase 1 project. With good progress being made, we remain on track for servicing in December 2023. Some of our key achievements during July include:

• completed all wastewater pipe tunnelling for the Austral carrier, Bonds Creek carrier, and Bonds Creek carrier lead-in
• nearing completion of wastewater pipe tunnelling for the Austral carrier lead-in
• ongoing delivery, excavation, and installation of maintenance holes – Austral carrier, Bonds Creek carrier, Kemps Creek carrier, Austral lead-in and Bonds Creek carrier lead-in
• installed wet well, valve chamber, electrical, water and power services to the new pumping station on Gurner Avenue

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

• completing wastewater pipe tunnelling for the Austral carrier lead-in
• completing the installation and testing of critical maintenance holes for the Bonds Creek Carrier and Bonds Creek Carrier lead-in
• continued installation and testing of maintenance holes for the Austral carrier, Bonds Creek carrier, and Bonds Creek Carrier lead-in with a view to have these completed by the end of August

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

The August 2023 monthly update will be posted on this page during early September 2023.
