Water Bowser Tanks & Trailers for Sale
Water Bowser Tanks and Trailers (325 to 2035 Gallons)
A water bowser is a towable water tank that delivers clean, potable water to any site a mains connection or hydrant cannot reach. Hitch it to a vehicle and tow it to site, giving remote work camps, municipal crews, outdoor events, and emergency response a self-contained drinking-water supply when the public supply goes down. Every water bowser in this line is built as a drinking-water unit first, with an NSF-61 rated polyethylene tank and food-grade fittings that keep the water safe to drink from fill to tap. Capacities run from 325 to 2035 gallons, so you can match the water bowser to your volume and your tow vehicle. The smaller and mid-range tanks are DOT approved, require no CDL, and pull behind a standard pickup, while the largest is a CDL-class unit for high-volume municipal supply. When a job calls for non-potable water instead, the same platform configures for general site duty.

Water Bowser Trailer Details
The water bowser line is built on one idea. Each size is a single convertible platform you order potable or non-potable, then fit with a pump chosen for the work, so no unit is locked to a single use. The potable build pairs an NSF-61 polyethylene tank with food-grade fittings for drinking water. The non-potable build is set up for general site water with a rear spray bar, drafting kit, and hose reel. Across the 325, 525, and 1000 gallon sizes you select from four pump options. The larger 2035 gallon water bowser uses a single high-volume pump on a heavier frame. You pick the size and the configuration, and the core platform stays the same.

Water Bowser Applications
Because every water bowser is convertible, applications split by configuration rather than by size. The potable build supplies drinking water for remote sites, work camps, events, and municipal and emergency use. The non-potable build handles jobsite water supply, washdown, general site and landscape watering, and fill duty. You choose the size for the volume you move and the configuration for the work, so the same line can serve a contractor crew, a parks department, or an event operator. The largest size suits high-volume municipal and emergency supply. A Sales Specialist can match the size, build, and pump to your application.
Water bowsers across the line are often used for:
- Municipal and Remote-Site Drinking Water (potable build)
- Jobsite Water Supply and Washdown (non-potable build)
- General Site and Landscape Watering (non-potable build)
- Event and Field Fill Duty
For freeze protection on your water bowser or skid, our water trailer heater blankets keep tanks at a constant temperature so fluids do not freeze in cold conditions. We customize thermal blankets to your tank size and shape. Call to learn more.
Water Bowser Frequently Asked Questions
Both, by configuration, and that holds across the line. Every size is ordered as a potable build with an NSF-61 rated tank and food-grade fittings, or as a non-potable build for general site water. The non-potable build is not rated for drinking water. A Sales Specialist sets up the right configuration for your size and use.
Four sizes: 325, 525, 1000, and 2035 gallons. The 325 is a light single-axle unit, the 525 and 1000 are tandem-axle, and the 2035 is a large CDL-class build for high-volume work. Choose by the water volume you move and your tow vehicle rating. A Sales Specialist can match the size to your job.
The 325, 525, and 1000 gallon water bowsers use four selectable pump options. Flow runs 32 to 180 GPM and pressure runs 34 to 106.4 PSI depending on the pump, covering standard, high-pressure, NSF-61 potable, and budget choices. The larger 2035 uses a single high-volume pump instead. A Sales Specialist can match the pump to your work.
Loaded weights are approximately 3,310 lbs for the 325, 5,978 lbs for the 525, and 10,940 lbs for the 1000, on a 3,500 to 12,000 lb GVWR by size. The 2035 is a CDL-class unit near 21,750 lbs loaded. You need a tow vehicle and hitch rated for the loaded weight. Confirm your rating with a Sales Specialist.
The 325, 525, and 1000 gallon water bowsers are DOT approved with no CDL, with LED recessed lighting, reflective stickers, electric brakes, a brake-away system, and a license plate mount and light. The larger 2035 is a CDL-class unit. A Sales Specialist can confirm what your state requires for your setup.
