Centurion Water is an Australian-based water and wastewater business with more than 20 years in the industry. Water is a scarce resource. Whether it’s for drinking, for industry or for reuse, we treat it so our clients can get more out of what they have.

We design, build, install, commission and service water and wastewater treatment systems for some of the world’s biggest miners and gas producers, industrial operations, state utilities and local councils. The work takes us all over Australia and Asia, from remote inland sites and islands to regional towns and major industrial hubs. Every project is different: new places, new people and new problems to solve. We’re a close-knit team, and we’re growing. Everyone pitches in, backs each other up and takes pride in doing the job properly. We work hard, but we also know how to have a good time along the way.

We’re also part of the global Centurion Group and the wider Centurion APAC team. Across the region, Centurion brings together water and wastewater treatment, workforce accommodation and camp services, lifting and power equipment hire, and equipment inspections and testing. That means more variety, bigger projects and plenty of people to learn from.
