Water Tanks Made to Fit Your Existing Vehicle

Fleets rarely stay the same for long. As workloads change, crews often need equipment that wasn’t originally part of the plan. Dust suppression becomes a priority, or road compaction requires steady water flow, or a tender suddenly calls for washdown capability. These moments usually trigger the same question: do we now need a dedicated water truck?

In many cases, the answer is no. You can convert the vehicle you already own into a fully functional water cart simply by adding a slide-in tank. This approach gives operators the performance of a purpose-built water truck without buying a new vehicle, modifying the tray, or taking the truck off the road for fabrication.

This is the strength of Allquip’s slide-in tanks. They allow you to upgrade instantly, work more flexibly, and keep your fleet productive without major capital spend. 

A Smarter Way to Increase Your Fleet Capability

Slide-in tanks are designed for operators who need water-cart capacity but do not want to dedicate an entire truck to a single task. These tanks work as complete, self-contained units that slide directly into a tipper body or flatbed. Once in place, your vehicle becomes a capable water truck with the same premium features you would expect from a custom-built setup.

The design also means you can remove the tank whenever you need the truck for other duties. This flexibility is especially valuable for contractors, councils, machinery hire businesses, and civil operators who juggle varied work and seasonal demands.

Allquip manufactures these tanks in a range of sizes and materials, so operators can match the tank to the exact vehicle and payload. Each one includes a warranty and is fully baffled to minimise water surge. This improves stability and reduces stress on the vehicle during sudden stops, turns, or work on uneven surfaces.

Premium Features You Can Add Without a Custom Build

One of the most appealing aspects of Allquip’s slide-in options is that they maintain the same functional capability as high-end water trucks. This includes optional high-performance features that are usually associated with dedicated builds.

Industrial-Grade Water Cannons

Every slide-in tank can be fitted with industrial water cannons. These are available in pneumatic, electric, and manual models, allowing operators to choose based on preferred control style and job requirements. Cannons are ideal for tasks such as dust suppression, stockpile wetting, washdowns, and general site spraying. Many operators appreciate the ability to operate these cannons using a radio remote control, which improves safety and convenience on busy worksites.

Spray Systems, Bars, and Nozzles

Allquip offers a wide range of spray systems, including pressure bars, dribble bars, and adjustable spray nozzles. These configurations make it easy to switch between different types of work, whether it is compaction on civil projects, landscape watering for councils, dust control in quarries, or surface preparation on roads. The flexibility to mix and match spray components means the same truck can handle multiple roles with only minor adjustments.

Water Pumps and Pressure Washers

Slide-in tanks can be fitted with pumps that match the operator’s workload. Whether you need a steady flow for compaction or high pressure for cleaning equipment, there is a pump setup to suit the application. Some operators also include pressure washers, complete with hoses and lances mounted directly to the slide-in frame. This adds even more value to the system by enabling cleaning tasks without bringing in separate equipment.

Easy Installation and Quick Removal

Time matters on work sites, and Allquip’s slide-in systems are built to minimise downtime. A key advantage is the option to include self-loading and unloading leg sets. With these legs installed, operators do not need forklifts or cranes to lift the tank on or off the vehicle. A single person can manage the process, allowing the truck to switch tasks in minutes.

This also makes the tank shareable across multiple trucks. If one vehicle needs maintenance, the tank can be moved to another. If a project demands additional water-cart capacity for only part of the day, a truck can be temporarily converted and then returned to its original role.

For operations that constantly adjust schedules and resources, this versatility offers major time and cost savings.

Engineered for Demanding Australian Work Environments

Conditions across Australia can be challenging for water trucks. Uneven ground, dusty regions, vibration from heavy machinery, and long days on site demand equipment that can withstand consistent strain. Allquip’s slide-in tanks are designed with durability in mind.

Every tank is fully baffled to stabilise water movement, which improves handling and reduces wear on the vehicle. The frames are built to withstand vibration and shock, ensuring the tank stays secure even when the truck is working on rough ground. Premium pumps, fittings, and spray components are selected to deliver reliable performance in dusty, wet, or high-impact environments.

For operators in quarries, mining, civil construction, and regional councils, this level of durability is essential. A slide-in tank is not just an accessory. It becomes a core piece of equipment that needs to perform reliably day after day.

Choosing the Right Slide-In Tank for Your Vehicle

Every fleet is different, so selecting the right tank is an important step. Here are the key points operators consider.

1. Size and Fit

The tank must match the truck’s body length, width, and payload. Allquip builds tanks in several capacity options, making it easier to choose a model that fits safely and efficiently.

2. Material Selection

 Polyethylene tanks offer long-term corrosion resistance with a lower upfront cost. Their natural flexibility helps absorb vibration and movement, reducing the risk of stress-related damage. Available as a premium module (5,000L to 11,000L) or a lightweight module (3,000L to 5,000L), the right choice depends on the job and the tank’s operating conditions.

3. Pump and Spray Configuration

Operators select pumps and spray systems based on their daily workload. A quarry may require heavy water flow for dust suppression, while a council may prefer adjustable spray bars for parks and streetscapes.

4. Cannon Installation

Some jobs require long-reach spraying or controlled high-volume output. In those cases, adding a water cannon can significantly improve performance.

5. Self-Loading Legs

Including self-loading legs provides the greatest operational flexibility, especially in fleets where trucks regularly rotate between different tasks.

Where Slide-In Tanks Deliver the Most Value

Slide-in tanks are useful across many industries because they allow operators to get the benefits of a water truck without permanently committing a vehicle to that function.

Construction and Civil Work

Ideal for road preparation, compaction, landscaping, dust suppression, and infrastructure work.

Quarries and Mining

Reliable for stockpile wetting, haul-road dust control, and washdowns.

Local Councils

Perfect for street cleaning, maintaining parks and green spaces, watering trees, and seasonal dust management.

Agriculture and Rural Operations

Useful for fire preparation, irrigation support, and general water delivery.

Contractors and Hire Companies

Allow equipment to be shared across trucks, job sites, and projects with almost no downtime.

Cost Effectiveness for Fleet Managers

A dedicated water truck is a major investment. Slide-in tanks provide an alternative that delivers similar capability at a significantly lower cost. Instead of purchasing a new vehicle, operators can use the truck they already own. Maintenance costs remain low, and the versatility of the tank helps fleets respond to workload changes faster.

This combination of performance and flexibility makes slide-in tanks one of the most cost-effective ways to expand fleet capability without permanent vehicle modification.
