550 Gallon Water Trailer

550 Gallon Express DOT Water Trailer

Compact Dust Control & Job-Site Water Wagon

The 550 Gallon Express DOT Water Trailer gives you a highway-legal, easy-to-tow water wagon for smaller jobs and tight sites. Built around a 550-gallon poly tank, tandem axle DOT trailer and gas-powered pump system, this unit is ready for dust control, compaction, cleanup and light fire support on and off the road.

LED lighting, quality brakes and heavy-duty construction help keep crews safe and compliant when towing on public roads, while the rear spray bar and hose kit let you put water exactly where you need it on the job site.

Express 550 DOT Water Trailer Overview

The 550 Gallon Express Water Trailer is designed for contractors and municipalities that need a compact, DOT-compliant trailer for everyday work. The 550-gallon poly tank is sized to keep weight manageable while still delivering enough water for dust control passes, soil compaction runs, landscape watering and equipment wash-downs.

A gas-powered Honda® engine and Tsurumi® pump provide reliable performance in the field, while the rear spray bar, hose and nozzle give you flexible water application options. Tandem axles, diamond-tread fenders and high-visibility LED lighting complete a package that’s built for regular towing on paved and gravel roads.

Common Uses for the 550 Gallon Express DOT Trailer

This 550 gallon water trailer is sized for crews that need frequent refills and easy maneuvering rather than all-day capacity. It’s a strong fit when you’re working in and around town, on smaller construction projects, or at facilities where public road towing is required.

• Road and utility construction dust control.
• Soil compaction and trench backfill work.
• Small site and subdivision development.
• Horse arenas and livestock areas near paved access.
• Parks, sports fields and public grounds maintenance.
• Residential and light commercial landscaping.
• Light brush-fire support and hot spot control (non-primary fire apparatus).
• Irrigation and vegetation watering in hard-to-reach areas.
• Equipment wash-down and cleanup where on-site water isn’t available.

If you routinely cover larger areas or need fewer refill trips, consider stepping up to our 800, 1,025 or 1,600 gallon DOT water trailers. Our team can help you compare capacity, tow weights and pump options across the full Express lineup.

Related Water Trailer & Tank Options

Need more capacity, potable water, or a different spray package? The 550 Gallon Express is one of several water trailer options we offer. Larger DOT models, arena trailers, potable water trailers and fire-fighting trailers are available when your project demands more gallons or specialized equipment.

We also supply standalone poly storage tanks in multiple shapes and sizes for customers who only need stationary storage. Horizontal leg tanks, pickup truck tanks and elliptical tanks can be paired with pumps and hose kits to build custom sprayer or transfer systems.

For freeze protection for your water trailer or skid, our Water Trailer Heater Blankets are exactly what you need. When cold weather affects the viscosity of fuel, fluids, and other materials you can lose production time, adding additional costs. Power blankets keep your tanks and smaller corrugated/steel tanks at constant temperature, preventing fluids from freezing in extreme conditions. We customize thermal blankets to meet your specific needs, no matter the tank size or shape. Call us today to find out more! Or visit our water trailers page to find other trailer sizes and options.
