When a water well is needed, most British Columbia well drillers use rotary drilling. In rotary drilling, the company inserts a pipe into the hole, along with a drill bit. The drilling company pumps fluid down the drill pipe and through the bit in order to carry the cuttings back up.
Air Rotary Drilling Explained
The fluid may be composed of water or organic chemicals, foam or air. If air is used to remove the cuttings, the company is “air rotary drilling.” At Cariboo Water Wells Ltd., we often opt for air rotary drilling because it’s an ideal way to drill rock. We can detect water quickly and can obtain water samples during drilling. It’s important that we keep the hole clear during air rotary drilling, which we do with water mixed with foam.
