Water Well Drilling Equipment
A lot of different elements make up the full line of water well drilling equipment. Different types of wells are made with shovels, or drilled with rotary drills. Let's take a look at some of them.
A dug well is exactly what the name implies. It's dug with water well drilling equipment, really digging, that consists of a shovel. These types of wells go at least as far back as biblical times. Jesus met a woman at Jacob's well. Many people are familiar with the stereotypical farm well. They generally have a roof to reduce debris falling into the well. They also include a crank to draw up the bucket.
Once this type of well is dug with what can be loosely called water well drilling equipment, a hand pump may be added. In addition the walls are often lined with stone. This served two purposes. First it reduced contamination from the surrounding ground. Second it reduced the chance of injury if someone fell into the well.
When the water well drilling equipment is a well point, a screen and a tripod, it results in a driven well. The point is hammered into the ground. Pipe sections are added as needed. Eventually this will reach groundwater. The pump is installed to deliver the water to the surface. It's pretty simple.
For reaching deeper water a different types of water well drilling equipments are needed. These include some types of rotary drill. That's a drill that turns to cut down into the ground. They can drill through dirt, clay, rock and anything else between the surface and the water. Once the deep water is found an electric pump is installed.
Water well drilling equipment includes a Cable Tool, which is the oldest form of drilling machine. It's still used. This tool raises and lowers a bit with force. The action also rotates the bit about 1/4 revolution per hit. Drilling must stop every so often so the debris can be cleared from the hole. It takes time, but it gets the job done.
Technically not water well drilling equipment, there are also pipes which line the resulting hole. These help prevent contamination. Sometimes this casing is driven or rotated into the well during the drilling process. Today this is generally PVC pipe sent down in sections. It's glued together during the process.
