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.
Why Construction Crews Rely on Water Trailers
A construction water tank trailer gives your team on-demand water without relying on hydrants, long hose runs, or expensive rental trucks. Whether you're controlling dust to support air quality compliance, washing down equipment before it leaves the site, or supplying water to remote areas without infrastructure, One Clarion has a trailer built for the job.
Dust Suppression
Control airborne dust to protect workers, meet regulations, and keep neighbors happy.
Construction sites generate enormous amounts of dust from grading, demolition, concrete cutting, and vehicle traffic—creating health hazards, triggering OSHA violations, and drawing complaints from neighbors. A dust control water trailer equipped with a spray bar provides blanket coverage across large areas, while the fire hose allows targeted wetting of problem zones. The self-contained pump system lets you suppress dust anywhere on site without hydrant access, helping you meet SWPPP and local air quality requirements.
- Spray bar covers up to 25-foot swath for fast, even coverage
- Reduce airborne dust during cutting, grading, and vehicle traffic
- Meet SWPPP and local air quality compliance requirements
- Honda engine and pump for reliable, all-day operation
- DOT-compliant for easy transport between job sites

Equipment Washdown
Keep machinery clean, extend equipment life, and prevent site contamination.
Heavy equipment accumulates mud, concrete, and debris that causes premature wear and can spread contamination between job sites. Most SWPPPs require wash stations to prevent trucks from tracking pollutants onto public roads, but without on-site water, crews waste time driving to remote facilities or risk compliance violations. A water trailer for construction sites serves as a portable wash station that can be positioned anywhere on site—the fire hose delivers high-volume water for fast rinse-downs, while the hose bib provides lower-pressure flow for detailed cleaning of tools and forms.
- Create wash stations anywhere—no plumbing required
- Fire hose for high-volume cleaning of buckets, undercarriages, and tracks
- Prevent cross-contamination between job sites
- Meet SWPPP track-out control requirements
- Clean concrete tools, forms, and mixers before material hardens
Recommended Trailers for Equipment Washdown

Commercial Pressure Washer Trailer
When caked-on mud and concrete require high-pressure cleaning power.
View DetailsRemote Site Water Supply
Deliver water where infrastructure doesn't exist—job sites, camps, and off-grid locations.
Many construction projects happen far from municipal water—rural developments, pipeline work, road construction, and utility installations all require water for mixing, cleaning, and daily operations. Trucking water in with rental tankers gets expensive fast. A DOT-compliant water trailer lets you haul water from any accessible source and deliver it exactly where it's needed. Larger capacity water trailers minimize trips, and for potable water needs, we offer NSF-certified tank options.
- Transport water from any fill source to remote locations
- Potable and non-potable tank options available
- DOT-compliant for safe highway travel between sites
- Suction kit available for filling from ponds or streams
- Quick-fill ports for fast hydrant fills when available

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.
Yes, we offer financing options for qualified buyers. Call us at 1-863-261-8388 to discuss terms and get a quick approval.
