How Water Well Drilling Rigs Works

Well drilling and well water are making a comeback at the moment. Wells are very simple in principle, but getting a smooth running experience can be a little tricky. Here’s the basics of well drilling rigs.

Where does well drilling come from?

At one time, drilling a well consist of nothing more than digging straight down until the aquifer level is reached. Evolution has, however, lead to sophisticate drilling rigs being used to bore the holes needed, with well pumps being used to draw water conveniently to the surface. Well drilling rigs are usually brought to the site of the new well dig via heavy trucking, as they can be incredibly heavy. The rig assembly itself will then be assembled and set in place. The drills then work essentially the same as any drill in your home maintenance plan- turning the interlocking steel or long cable bits to bore down into the earth in a clockwise direction. Ideally, PVC or steel should be used to reinforce the hole created. This will also avoid contamination making their way into the water. Often, depending on the size of the project, these well drilling rigs will become so hot during use that lubricants and muds are needed to prevent accidents. Some make use of this to their advantage by using specially designed ‘muds’ suited to the boring surface as the bit spins through each layer, making the job faster and neater. More details here.

What happens after well drilling occurs?

Of course, simply drilling the well is not really the end of it. It’s vital for the water to be brought safely to the surface and filtered in order for it to be potable for human consumption. Filters also prevent large particles making their way into the water pump and clogging the works. These most often consist of simple screens and gravel. Water can then be either pumped directly from the well on demand, or pumped via well pump into secondary water tanks. This approach is often taken to ensure water is available on demand at all times, but cut down on the cost of running the well pump as it does not have to run on demand or continuously.  Smaller pumps will then provide the water pressure necessary to pressurise the system.

Why would I want well water?

Depending on your situation, of course, well water could well be the only access to water you have. Isolated hamlets, farms and more can all benefit from pumping their own water rather then being attached to wider infrastructure. It can be cheaper, simple to run, and depends on no outside parties for a continuous access to clean running water. While initial outlay can be large, it will quickly become self-sustaining with only maintenance to consider. Of course, some opt for well water above poor quality, sometimes contaminate urban water as well, deeming the water better tasting, less contaminated and healthier then that available from the municipality.
