Estimate water needed for dust control or compaction, and how many tank loads the job requires.
For estimation purposes only. Terms of Use
A 20,000 m² haul road at 1 L/m² with an 80% spray efficiency and a 12,000 L truck:
Use this when scheduling water trucks for dust control on haul roads, site prep, or compaction watering — so you know how many loads and how much truck time the job needs.
This is a planning estimate. Actual water demand depends on soil type, weather, temperature, and the number of passes — adjust application rates with field conditions.
A light application on a haul road is roughly 0.5–1 L/m²; heavier treatments or dry conditions can go higher. Start low and adjust based on what the site needs.
Not all water from the spray bar lands where you want it. Wind, overspray, and runoff typically reduce effectiveness to 70–90%, so we include it in the calculation.
