In Australia’s harsh operating environments, water truck reliability isn’t just about tank capacity or spray coverage—it’s about longevity. And longevity starts at the chassis.
Many tank suppliers lean heavily on galvanising to market their product—protecting the tank from corrosion. But here’s the reality:
In most failures we’ve seen, it’s not the tank that gives out first. It’s the truck.
Cracked rails, corroded flanges, premature rust-through—all common outcomes when water ingress and torsional stress go unmanaged. Galvanisation might extend tank life, but it does nothing to protect the cab chassis from water damage. And that’s where the real cost sits.
The Real Problem: Water on the Rails, Not Rust on the Tank
Over decades of builds and rebuilds, we’ve seen what causes long-term chassis degradation:
-
Overfill runoff pooling in chassis crevices
-
Gaps between tank mounts and subframes becoming corrosion traps
-
Drips and spray deflecting back onto rails and suspension components
-
Lack of protective coating inside OEM chassis sections before tank fitment
These issues have nothing to do with the tank material—and everything to do with tank integration.
Our WT30 Water Tank Range: Designed to Protect the Whole Truck
At Any Type Trucks, the WT30 Water Tank Range was engineered from the ground up with one purpose:
Preserve and extend the working life of your entire vehicle—not just the tank.
Here’s how:
✅ Full-Length Guards with Integrated Brush Seals
These run along the entire base of the tank to prevent overfill water from wrapping around and tracking into the chassis rails—an often-overlooked source of hidden corrosion.
✅ Sealed Subframe Gaps After Fitment
Every WT30 includes a sealed subframe interface post-installation. This eliminates water traps between structural members, preventing slow corrosion over time.
✅ Optional Chassis Seal & Paint Service
We offer pre-fitment chassis preparation, including internal and external sealing using Epinamal DTM coatings. This seals inner chassis rails, strengthens corrosion resistance, and helps preserve the OEM chassis integrity for the long haul.
✅ New Lid Design That Directs Water Off the Rear
Influenced by Road Tanker Standards, our redesigned tank lid includes built-in water control shaping. It directs water flow away from the cabin and forward running gear, shedding runoff out the back where it belongs.
So Why Galvanise the Tank?
We’re not against galvanisation—it can be effective in the right application. But let’s be clear:
-
Tanks are easy to repaint or replace.
-
Chassis rails are not.
If your tank lasts 15 years but your truck’s chassis fails in five due to rust and poor integration, the galvanised tank doesn’t save you—it costs you.
Our approach is different. We focus on protecting the entire asset, so your truck stays operational, compliant, and valuable well beyond its initial term.
Backed by Experience, Built for Performance
With more than 30 years building water trucks for mine sites, councils, and major contractors, we’ve seen what works—and what doesn’t. That’s why our WT30 is the tank of choice for fleet owners who care about whole-of-life performance and asset integrity.
