New Project Announcement: RAAF Base Amberley STP

A great milestone was achieved in late 2022 with the contract signing for the Delivery and Operations & Maintenance Phases of the RAAF Base Amberley Sewage Treatment Plant (STP) project.

Following installation, commissioning, and rigorous validation and verification, the replacement STP will begin the O&M phase in Q3 2024.

It has been great working with our client, Defence, and the PMCA, Jacobs, as well as our key partners Beca, Laurie Curran Water, ECT2, Epic Environmental, and ACOR throughout the Development Phase.

St Hilliers is excited to be delivering this key Defence project with this high performing group of specialists.
