Water Trailers

truck towing a water trailer

Water trailers for hauling, field work and on-site storage

We carry three kinds of water trailer. Water wagons (525 to 2,010 gallons) haul water on public roads; the Express wagons are DOT approved, with surge or electric brakes, and come in NSF potable versions for drinking water. Nurse trailers (1,010 to 1,600 gallons) carry water and spray mixes to the field: Enduraplas Limited Series trailers are DOT approved, and Select Series trailers are for farm and job-site use off public roads (non-DOT). Relocatable storage trailers (5,000 to 9,000 gallons) hold water on site and move between jobs.

Not sure which you need? DOT-approved trailers are built to be towed on public roads; non-DOT trailers stay on the farm or site. Electric brakes need a brake controller in the tow vehicle; surge brakes work on their own. Call us or request a trailer quote and a tank specialist will match a trailer to your load and tow vehicle.

Water Trailers & Skids

Choosing a water trailer

The right trailer depends on how you will tow it, what you are spraying or delivering, and whether you need DOT approval or potable water. Use this overview to match your job to a trailer family, then open each model for its specs.

Trailer types

  • DOT water wagons: Express wagons from 550 to 2,010 gallons, with lighting, brakes and running gear set up for public roads, plus a 525-gallon industrial trailer. Used for road construction, dust control, soil compaction and utility work.
  • Arena and farm trailers: 500 and 1,025 gallon Arena Ag trailers with spray bars for arena footing, dust control and livestock areas, easy to maneuver on ranch and farm roads.
  • Potable water trailers: potable-rated tanks and components for drinking water at camps, events and remote sites, crew hydration and emergency supply. Choose Express potable wagons from 500 to 2,010 gallons, or gravity-fed and distribution models.
  • Nurse trailers: Enduraplas trailers from 1,010 to 1,600 gallons carry water or water-based solutions such as fertilizers, insecticides and herbicides to the field. Cone-bottom versions drain completely.
  • Wash trailers: self-contained 500-gallon trailers with a cold-water or hot-water (gasoline or diesel) washer, tank and hose reel for cleaning equipment, buildings and job sites.
  • Combo generator trailers: a 500-gallon water tank with a 15 kW or 20 kW generator (the 20 kW model adds LED lights) for construction sites, oil fields and remote camps that need water and power in one unit.
  • Relocatable storage trailers: Enduraplas 5,000 and 6,000 gallon double-cone and 9,000 gallon triple-cone trailers hold water on site and move between jobs.

What comes standard

Each product page lists its own package, but most Express water wagons include:

  • A polyethylene tank, with integrated baffles on many models.
  • A heavy-duty frame, jack, safety chains and properly rated axles.
  • An engine and pump package sized for spray bars, nozzles or hose reels.
  • Rear spray bars, side nozzles or hose bibs, depending on the model.
  • Flush and drain fittings that make cleaning and winterizing easier.

Options can include upgraded pumps, extra hose reels, electric start and DOT lighting packages.

Water trailer questions

Do I need a DOT water trailer? If you plan to tow on public roads at speed, a DOT-compliant trailer is usually required. For use only inside a plant, job site, ranch or farm, a non-DOT trailer may be acceptable. Your local regulations and insurer decide what is needed.

What size should I choose? Size depends on how much area you need to cover, how often you can refill and what you tow with. Contractors often choose 1,000 to 1,600 gallon trailers for road work and compaction, while arena and small farm users prefer 500 to 1,025 gallon units that are easier to maneuver and tow.

Can these trailers carry drinking water? Only potable models are built and outfitted for drinking water. If you need potable water, choose a potable-rated trailer and do not use it for chemicals or non-potable liquids.

Tell us about your project and tow vehicle, and we will help you match tank size, trailer type and pump package to the job.
