How much water to apply per unit of treated surface — US dust-control plans usually state this in gal/yd².
Use the rate specified in your site's dust control plan or environmental permit — it varies with soil type, moisture content, wind, and site conditions.
The total jobsite surface area requiring dust suppression.
Include haul roads, staging areas, and any other exposed surfaces covered by the current application pass.
The usable tank capacity of the water truck being used.
Confirm the specific truck's rated tank capacity with your hauler or fleet — usable capacity may be slightly below the tank's nominal rating.

The correct application rate depends on soil type, moisture, wind conditions, and your jobsite's specific dust control plan or environmental permit requirements — this calculator applies whatever rate you supply, it does not determine the required rate for your site.

How this was calculated
Formula source(s)
- Total water needed = Application Rate × Area to be Treated; Truck loads needed = ceil(Total Water ÷ Truck Tank Capacity). Dust suppression application rates vary with soil type, moisture content, wind, and site conditions — the specific rate should come from your site's dust control plan or environmental compliance requirements, not a single universal constant.
Inputs used
- Application Rate
- 0.44 gal/yd²
- Area to be Treated
- 53820 sq ft
- Water Truck Tank Capacity
- 2000 gal
Intermediate steps
- Water truck loads needed
- 2 loads

What this calculation does not cover
- This is one pass, and dust control is not a one-pass job. Water put on a haul road leaves by evaporation and on the wheels running over it — on a hot, windy summer day a working road can need re-wetting every hour or two, so a day's demand is this figure multiplied by the number of passes that day. Sizing a supply off a single application is how a site runs dry by mid-afternoon with the road smoking.
- More water is not the safer answer. Past the point the surface will hold, the excess runs off carrying fines into the drainage the site is permitted to protect, softens the subgrade under the very roads being compacted, and turns the exit into mud that tracks onto the public road — and track-out is the violation sites are most often cited for. The rate is a ceiling as much as it is a target.
- Loads are not a schedule. A truck's cycle is fill, travel, spread and return, and the spreading itself happens at a walking-pace ground speed over a fixed width, so how many of these loads land in a shift depends on the haul to the fill point and how many trucks are on it. Eight loads can be one truck working all day or two trucks finished before lunch, and only the second keeps the surface damp continuously.
