The water well drilling rig DTH
hammer excels at clearing cuttings with high-pressure air.
-
Fast removal: Speed reaches 2-3m/s, 5-8x faster than mud circulation. Great for permeable sandstone.
-
Handles gravel: Blows out <50mm gravel in sandy cobble layers. A river project drilled 50m with only 30mm residue.
-
Less well pollution: Avoids chemical leakage into aquifers. One test saw 15% higher water quality compliance.
Traditional mud drilling needs frequent cleaning. The water well drilling rig stays efficient with cleaner holes.
