We’ve brought together two of Australia’s water specialists, WestWater and Centurion Water & Wastewater Solutions (formerly Tristar), into one team. From late September 2026, we’ll operate under a single name: Centurion Water.
For you, the important part: it’s the same people you already work with, now backed by a wider capability and a bigger resource base. Your projects, contacts and quality of service continue as normal, there’s nothing you need to do.
What we now offer
> A broader range of treatment solutions – from potable and process water to industrial wastewater
> One team for full project delivery – design, build, installation, commissioning, training, operation, servicing and support
> More ways to get what you need – rental, upgrade, refurbishment, or custom-built, for short-term through to permanent
> We also keep your plant supplied – spare parts, filters, membranes and treatment chemicals — and sell the components and instrumentation your plant runs on, whether it’s one of ours or a third-party system
> 24/7 Australia-wide support, onsite or remote, for both our own and third-party systems
What this means for you
> A broader range of solutions from one partner – so you’re not managing multiple suppliers
> Faster delivery, supported by greater capability and resources
> Simpler project management – one team supporting you from start to finish
> Confidence in long-term plant performance
In short: less complexity for your team, and greater confidence that your plant will be delivered on time and supported properly.
What we do
We design, build, install, commission, operate and service water and wastewater treatment plants for councils, utilities, mining, renewables, construction and remote sites — and we keep them running long after handover.
