Custom WaterDog Tanks & Trailers Built to Last
Our WaterDog Trailers are built from industrial-grade materials and undergo rigorous testing and quality control processes to make sure they are safe, dependable, and durable.
Our water tanks and trailers can handle any terrain, any environment, and any climate, no matter how extreme. This makes them ideal for rural and agricultural areas, disaster relief areas, construction sites, and mining facilities. They are easy enough to use that a second-grader can operate them.
We serve residential and commercial customers as well as government agencies and disaster relief agencies across the U.S. and around the world. We will work closely with you to customize your water trailer to your needs.

We will work closely with you to make sure you get a water tank, trailer, or skid that is perfectly designed to meet your specific needs. Each water trailer is designed to perform a specific task and more and can be fitted with any parts or accessories you need for the job, from spray attachments and hydrant full pipes to hose reels and control manifolds.

About Our Products
What sets our water hauling trailers and water tanks apart from the rest is our process of manufacture. We design our equipment to be used for numerous applications and to outlast the competition.
Frames
Our frames come out of a manufacturing machine shop. Steel angle and channel iron are welded together by educated, experienced welders. Every trailer frame includes an emergency breakaway system and electric brakes. The frame comes with a one-year warranty.
Tanks
Our tanks are molded out of state-of-the-art polyethylene and are repairable and replaceable. Tanks come in either black or white. The tank carries a three-year warranty. All tanks are mounted in place on the trailer frame by steel bands.
Tires and Lights
The included tires are D-rated for the 325-gallon and 525-gallon water tanks, G-rated for the 1000-gallon water tanks, and E-rated for the 2,035-gallon water tanks. Every trailer is equipped with DOT-approved recessed lighting and DOT-approved brakes on all axles.
M.C.O.
Since we are a licensed trailer manufacturer and a licensed new motor vehicle dealer, we will attach to your paid receipt a Manufacturer’s Certificate of Origin for each trailer purchased. This document is similar to the title of a car. It will allow you to obtain a license plate and tags for your new water trailer.
