Dust-Control Watering Volume and Truck Trips
Gallons a water truck spreads on a haul road and the trips to keep the fugitive-dust permit satisfied.
Example
You enter
- Watered length (ft) 2000
- Watered width (ft) 20
- Application rate (gal/sy) 0.5
- Water truck capacity (gal) 4000
- Passes per day (count) 6
You get
- Area (SY) 4444.44
- Gallons per application 2222.22
- Trips per app 1
- Daily water and trips 13333.3
- Daily trips 6
Details, formula, and sources
gallons = area/9 x rate (gal/sy); trips = ceil(gallons / truck capacity). A 2,000 ft x 20 ft road at 0.5 gal/sy is 2,222 gal an application (one 4,000-gal load); at six passes a day that is ~13,300 gal over six trips. The dust plan and AHJ air permit set the rate and frequency; frequency, not area, drives the water budget.
area_sy = length_ft x width_ft / 9; gal_per_app = area_sy x rate_gal_per_sy; trips_per_app = ceil(gal_per_app / truck_cap_gal); daily_gal = gal_per_app x applications_per_day.
Dust-control watering identity by name (gallons = area x rate; trips = ceil(gallons / capacity)); first-principles volume arithmetic.
The watering arithmetic is public quantity geometry; the application rate and frequency come from the site's fugitive-dust plan and AHJ air permit.
Estimate. AHJ and licensed professional govern.
