Water Well Drilling Equipment & Complete Solutions
Bench blasting is won or lost on three numbers β hole diameter, bench depth and rock hardness. Tell us those and we size the rig, the air package and the tooling as one system.
The chassis decision drives half the operating cost of a water-well business β choose by terrain, transport distance, well depth and hole diameter.

1. Chassis first, rig second
How the rig moves between wells is the single biggest cost lever. Crawler units live on site, wheeled units drive themselves between nearby wells, and truck-mounted units travel between provinces at highway speed.
| Chassis | Typical depth range | Between wells | Best for |
|---|---|---|---|
| Crawler | 180β1000 m | Lowboy haul | Soft ground, long campaigns at one site |
| Wheeled | 130β200 m | Own power | Villages and farms close together |
| Truck-mounted | 300β1500 m | Highway speed | Contracting across a wide region |
2. Match the compressor to the well programme
Deep wells need high-pressure air. Shallow irrigation wells do not. Match the compressor class to the deepest hole in the campaign, and use dual-mode switching where one machine must serve wells of different depths.
| Well depth | Air pressure class | Compressor class |
|---|---|---|
| up to 200 m | 1.7 MPa | 18 mΒ³/min high-pressure mobile |
| 200β450 m | 2.3 MPa | 25β30 mΒ³/min high-pressure mobile |
| 450 m+ | 2.5β3.5 MPa | High-pressure deep-well family |
3. What to send us
Well depth, target diameter, casing size, terrain and how far you move between wells. With those five we can confirm chassis, rig class and air package before quotation.

Matching Air Compressors
Air demand is set by the hammer, not the rig. Discharge pressure must cover the hammer rating and free air delivery must cover air consumption plus margin.

Request This PackageFrequently Asked Questions
Rig selection
Which drilling rig should I use for water well drilling?
It depends on hole diameter and depth. In our current range, 29 rig models have a published hole range for this work; the largest-capacity three are KG550 (hole 115β254 mm), KT20S (hole 135β254 mm), KT30 (hole 195β254 mm). Send us hole diameter, depth and rock type and we will confirm the fit.
Which drilling rigs are recommended for water well drilling?
Based on the published hole range of the rigs listed for this application, the widest-coverage models are CDT-600 Trailer Water Well Drilling Rig (up to 950 mm), CDC-600 (up to 850 mm), CDT-800J Trailer water well drilling rig (up to 850 mm). Final selection depends on hole diameter, bench depth and rock conditions β use the equipment selector for a parameter-matched shortlist.
What is the maximum drilling depth for water well drilling?
The deepest published capability among the listed models is 1300 m (KSC-1300, CZT-1200). Note that economical depth depends on method and tooling: a split rig with a separate compressor is normally economical to about 25 m per bench, while deeper holes need matched rod strings.
Which drilling tools match the rigs used in water well drilling?
The parameter-matched tooling for the listed rigs is hammers: K10; rods: 76mm Drill Rods, 102mm Drill Rods. Tool selection follows the hammer class and the required hole diameter.
How many models are available for water well drilling?
10 rig models are currently listed against this application, and matched compressors, hammers, bits and rods are linked to each of them. The complete package can be assembled and quoted as one configuration.
Hole diameter
What hole diameter range can be drilled?
Across the rigs we list for this application the published hole range spans 32β254 mm. Depth capability and rock hardness decide which end of that range applies β tell us the diameter and bench depth and we will match the model.
What hole diameter range can be drilled in water well drilling?
Across the rigs listed for this application the published hole range spans 89β950 mm. Smaller diameters favour mid-size rigs with higher drilling frequency; larger diameters need a heavier carrier and matched air volume.
Air compressor
What air compressor is required?
Air demand is set by the hammer, not the rig. The compressors we list for this application cover 5β45 mΒ³/min and discharge pressures from 8 to 35 bar. Match the compressor's free air delivery to the hammer's consumption (plus a 10β15% margin) and make sure discharge pressure covers the hammer rating.
What air compressor is required for water well drilling?
Air demand is set by the hammer, not the rig. Parameter-matched compressors for the rigs in this application include LGCY-33/25, KSCY-550/13. Match the compressor's working pressure and free air delivery to the hammer class you intend to run.
