Many companies that sell water drilling rigs offer training on how to use them effectively. Training classes run from an afternoon to five days in length and go into the mechanics of water drilling rigs and how to use them to find water effectively.

Mechanical rigs work best for those who will only use them once or twice a month in an area that is mostly free of large rocks. For regular use or in a rocky area, opt for a hydraulic rig.

Mechanical rigs operate when an engine drives a rotary into the ground and the pipe is raised using a hand winch. The hydraulic rig works by driving both the rotary and draw with a remote power unit. As the rotary digs into the ground, the mud pump pulls the mud from the pit and places it in a settling pit. The bits used on a water drilling rig generally range from 3 7/8 inches to 5 7/8 inches and feed into a 4-foot by six-foot casing pipe. Those wanting to drill to a depth of at least 150 feet on a regular basis should opt for the hydraulic rig.
