Three Types Of Water Well Drills And Why Your Contractor Would Use One Over The Others

Posted on: 13 November 2015

People generally assume that when a contractor drills for a water well, there is one type of drill and a one-size-fits-all hole. This, however, is not the case. There is much to consider when drilling a water well, particularly if the drill will have to go through some thick, solid rock to get to the source of the water. Here are three types of water well drills for water well drilling and why your contractor would choose one over the others.

Truck-Mounted Drill

A truck-mounted drill is able to draw on the power of the truck itself, reducing the need for an additional power source for the drill. Instead of a power generator and the construction of a rig platform, the drill relies on the truck to provide continuous power and a very stable platform. The truck has anchoring legs that let down and keep the truck from gyrating all over while the drill does its work. A contractor might choose a truck-mounted drill over a pull-behind drill rig for convenience; it sets up quickly and breaks down quickly. It also has the greatest capacity to dig the deepest wells.

Pull-Behind Drill Rig

A stand-alone, pull-behind drill rig is its own mobile platform and anchors. It tends to be a little less stable than a truck-mounted drill, but it can drill smaller, more precise holes for wells that are closer to the surface. A pull-behind drill is ideal for a contractor who may have several well-drilling projects to do in a single day and may not have several truck-mounted drills he or she can send around to all the sites. It is also an effective choice when a drilling site currently has a power source (i.e., a generator) already on the premises.

Portable Drills: Manual and Hydraulic

Portable drills are the type of water well drills you can rent and use yourself, if you already know where on your property you can drill for water. Similar to jackhammers, these portable well drills have pole bases which the operator stands on to stabilize the drill while it is working.

It comes in two varieties:

  1. Manual, which requires a great deal of strength to operate because you have to hold and press down on the drill as it carves out a hole leading down to the water, and
  2. Hydraulic, which utilizes hydraulic power to do all of the work for you

These portable drills would be selected by your well drilling contractor like one from Merritt Well & Pump if the water is less than two or three hundred feet down, and IF the earth is soft and lacking in solid rock.
