4000L AquaTrans™ Portable Water Cartage Tank

The 4000L water tank is a great size for operators who need decent capacity without overloading smaller trucks or trailers. It’s commonly used for:

• Dust control on worksites and driveways
• Watering stock in paddocks
• Firefighting backup for rural properties
• Washing down machinery or vehicles
• Topping up sprayers or mixing chemical blends

It gives you the flexibility to cover a lot of ground without needing a full-sized water cart.

Like all our cartage tanks, the 4000L portable water tank is packed with practical features designed to make life easier on site. These include:

• A fully drainable sump to get the tank completely empty without tipping or tilting
• UV-stabilised, food-grade poly that holds up to years of sun, weather and regular use
• Tough, impact-resistant walls that handle knocks on and off the road
• A flat base and forkable design for safe transport and easy loading
• Smooth internal walls that make rinsing and cleaning quick work
• Optional steel frame for those needing extra structure or tie-down points

The 4000L portable water tank is best suited to medium-duty trailers or flatbed trucks. Its shape and size make it easy to mount securely without overloading the vehicle. If you’re not sure about weight distribution or tie-down spacing, we can help make sure it fits your setup properly.

These tanks are designed to be low-maintenance. Give it a clean now and then, especially if you’ve used it for anything other than clean water. Check over the fittings, valves and hose connections every so often to make sure nothing’s working loose. Thanks to the smooth interior and rust-proof poly, it doesn’t take much to keep it in good shape.

A 4000L water tank gives you a solid water supply without needing a heavy-duty truck. It’s easier to handle, fits a wider range of trailers and vehicles, and is quicker to fill and clean. If your jobs don’t always need bulk cartage but you still want enough capacity to avoid constant refilling, it’s a smart middle ground. Plus, it’s light enough when empty to move around without too much hassle.
