Construction Water Tank Trailers
Towable water tank trailers with pumps for dust suppression, equipment washdown, and remote site operations. DOT-compliant options from 500 to 2,000+ gallons.
Construction Water Trailer Applications
Construction water trailers give crews a mobile, self-contained water supply for the work that comes up on almost every jobsite. The core uses are dust suppression and dust control during grading, demolition, and concrete cutting; equipment washdown to rinse machines, tracks, and forms before they leave the site; soil compaction and site watering for moisture conditioning during earthwork; and remote fill for jobsites with no hydrant or permanent water nearby. A single trailer with a spray bar, fire hose, and the right pump can handle most of these without paying for a rented water truck.
The right trailer comes down to how you run the job. Tank capacity, pump output, spray width, and DOT or non-DOT configuration all shift with site size, how far you tow between jobs, and how often you refill. The guides above break down each application in detail, from construction dust control and demolition to soil compaction, equipment washdown, remote hauling, and OSHA silica and SWPPP compliance. When you are ready to match a trailer to your fleet, a Sales Specialist can help you size it.

Towing & Transport Considerations
Use this checklist to confirm your tow vehicle, jobsite conditions, and travel requirements.
| What to Confirm | Why It Matters | What to Do |
|---|---|---|
| Tow rating | A full tank plus trailer weight can exceed your truck's safe towing limits. | Confirm towing capacity and plan for the weight of water, trailer, and any accessories. |
| Hitch type | The coupler/pintle must match your vehicle for safe towing and compliance. | Verify coupler size or pintle setup required for the model you want. |
| Brake type | Braking requirements vary by trailer configuration and travel conditions. | Confirm whether surge or electric brakes are included/required for your setup. |
| Lighting & wiring | Road travel typically requires proper lighting and compatible wiring connections. | Confirm your truck connection matches the trailer's lighting requirements. |
| Jobsite maneuvering | Tight gates, backing, and turning radius affect day-to-day usability. | Choose capacity and trailer size based on access constraints and how often you move it on site. |
| Where you travel | Public-road towing generally requires DOT-compliant equipment; private property use may not. | If you move between job sites on public roads, choose DOT-compliant. For single-site use, non-DOT may fit. |

Frequently Asked Questions
For dust suppression on most job sites, a 500-1000 gallon trailer handles daily operations. Larger sites or all-day watering may require 1600+ gallons to reduce refill trips. For equipment washdown, 500-800 gallons is typically sufficient. Call us with your site details and we'll help you size it right.
If you're towing on public roads between job sites, yes - DOT compliance is required for highway travel. If the trailer stays on a single property or private roads, a non-DOT trailer works fine and costs less upfront.
For most construction dust suppression, crews choose a pump that can run a rear spray bar and a fire hose for targeted wetting. The right pump depends on how long you run each day, spray bar style, hose length, and whether you need to pull from an external source. Tell us your site size and watering schedule and we'll recommend the best configuration.
Yes. Many configurations support filling from accessible sources using a suction kit. If you plan to draft from ponds or tanks, we'll help you confirm pump compatibility and recommended accessories for reliable filling.
Not always. Water buffalo often refers to potable water transport for drinking water and sanitation (commonly NSF-related). Construction water trailers are frequently configured for dust suppression and washdown using spray bars and hoses. We offer both. Tell us whether your use is potable or non-potable and we'll point you to the right option.
