Express 800 Water Wagon

800 Gallon Express Trailer

High-Capacity DOT Water Wagon – No CDL Required*

The 800 Gallon Express DOT Water Trailer gives you more capacity than a 550 while still being towable without a CDL in many areas.* It’s a favorite with contractors, rental fleets and municipalities that need reliable dust control, soil compaction and job-site water delivery on and off the highway.

Built around an 800-gallon poly elliptical leg tank, tandem drop axles and a DOT-approved trailer frame, this unit includes a Honda® engine, 2" Tsurumi® pump, galvanized spray bar and fire hose so you can spray roads, pack subgrade, cool concrete saws or handle light fire support with one trailer.
(*Check local requirements.)

Express 800 DOT Water Trailer Overview

The 800 Gallon Express Water Wagon is built for crews that need more gallons between refills without jumping up to a 1,000+ gallon rig. Drop axles lower the tank’s center of gravity for stable towing, while 16" tires on Accu-Lube hubs and tandem 6,000 lb leaf-spring axles are sized for regular use on gravel and paved roads. A 4 HP Honda engine and 2" aluminum Tsurumi pump move water quickly through galvanized suction and discharge manifolds. The rear spray bar covers up to a 25' swath for road and pad work, and the included fire hose gives you controlled stream flow for spot watering, wash-downs or small fire hot spots.

• Cooling concrete saws and cutting operations.
