500 Gal. Water Trailer

The 500 gallon dual axle ABI Water Trailer hauls and applies large volumes of water around the farm or property. This commercial-grade trailer, built on a custom proprietary frame, can be towed by a tractor, truck, or SUV. The dual axle design provides more stability and disperses the trailers weight over more surface area. It is powered by an engine and pump to apply variable amounts of water from either the rear spray nozzles (wide spray) or the available spray hose (spot application). Additionally, it has the ability to turn the flow of water on and off, on-the-fly, from the seat of the tow vehicle. Common uses include dust abatement, irrigation, hydration, watering, washing, and supplying in applications such as horse arenas, general property, nurseries, ballfields, pools, parks, farms, and more! The ABI Water Trailer comes loaded with features making this an invaluable and versatile trailer for your water hauling and application needs. A potable (drinking) water configuration is also available. Not for use on public roadways. See D.O.T. models if road use is required.

Our full line of ABI Water Trailers excel at arena moisture management, landscaping, dust abatement, property fire protection, cleaning equipment, stalls, and buildings, transporting potable water, and more! Whatever is on your list of jobs to accomplish with your ABI Water Trailer, we’ve loaded it with thoughtful features that help you get them done quicker and better than before. With quick and convenient filling capabilities, easy-to-use hoses and spray nozzles, and a full-drain tank on our custom-built frame, our water trailers are easy to fill, easy to operate, and easy to own!

500 Gallon Tank

Purpose-Built Rugged Steel Frame

Built Better Than The Rest

No matter how you spin it, a water trailer is only as good as the frame it’s built upon. Our frames are purpose-built and are NOT converted car haulers or a purchased component (like many competitors’). We design and build our own frames, giving us complete control of durability, safety, and functionality. No matter the size, our frames are constructed of fully-welded steel (no wood!), have an adjustable hitch with choice of coupler, and feature leaf-spring or torsion suspension.

500 Gallon Tank

Full-Drain Custom Molded Tank

Fully Drain For Easy Cleaning

Each tank is rotationally-molded and fully drains for easy cleaning. Many competitors’ tanks do not fully drain, making it nearly impossible to throughly clean (needed for potable water usage) or flush out sediment from filling the tank with pond water. Most ABI models have elliptical tanks for easy access and a lower center of gravity. Choose between a white tank for easy water filling visibility or a black tank to reduce algae growth during water storage. The shape of our tanks also helps to minimize water sloshing during use.

500 Gallon Water Trailer Spray Plumbing

Motor, Pump, & Plumbing System

Enable Precision Application Of Water

The available motor, pump, & plumbing systems enable precision application of water for a variety of applications. Depending on the model, we offer powerful Honda and Briggs & Stratton brand engines that are then perfectly matched with the right pump to maximize performance for the trailer’s application. We expect impressive performance, so the entire plumbing system is equipped with the best quality valves and the ability to adjust water pressure and flow from the engine, the valves, or a combination of the two.

Spray Nozzel

Spray System & Brass Nozzles

Ensures A Consistent Application Of Water

The available rear spray system with brass nozzle(s) ensures a consistent application of water to the ground when configured with a motor and pump. The brass nozzle(s) provide superb coverage and can be adjusted to direct the spray as desired. Our full-size water trailers come standard with 3 nozzles on a steel spray bar that also include valves to selectively turn the outer nozzles on or off, or to adjust their flow. The compact-size water trailers have either 1 or 2 nozzles depending on the application.

500 Gallon Water Trailer Spray Hose

Convenient, Powerful Spray Hose

Perfect For Countless Applications

The available spray hose extends the functionality of trailers equipped with a motor and pump. The spray hose is perfect for cleaning projects, watering landscaping, filling troughs, fire protection, and countless other applications! Easily stores on the carrying rack and includes quick-couplers to connect and disconnect with ease.

Flow Control

Easy On/Off Flow Control

Without Getting Off Of The Tractor Or ATV

A ratcheting valve and attached rope enables the tractor operator to turn the flow of water on and off without getting off of the tractor or ATV! Shutting off water flow when traveling over areas that have already been watered conserves water and eliminates inconsistent or over-watering that can be detrimental in certain applications. Add the optional electric on/off control for use inside a truck or other commercial applications!


Auto-Fill Shut Off

Saves Time, Hassle, & Worry

This new valve automatically shuts off the flow of water from a garden hose when the tank is full, saving time and worry. Now you can fill the tank overnight or continue on with your day’s work, and the trailer will be full and ready to spray when you are.

Quick FIll

Quick Fill System

Easy Filling Of The Tank

For water trailers equipped with a motor and pump, the available quick-fill system allows easy filling of the tank from a pond or other available water source in mere minutes. These hoses feature quick couplers and conveniently stores on the carrying rack.


Honda GX160 Engine

Delivers More Power

All full-size Water Trailers are fitted with a Honda GX160 engine, which provides 163cc & 5 hp of power to the durable poly-pump. With 2″ plumbing and valves, our pump is capable of 195 gpm flow rate. The engine, as well as the entire trailer, comes standard with 36 month commercial warranty!
