Groundwater Extraction Process Explained Groundwater Extraction Process Explained

The groundwater extraction process is an important part of everyday life, but many people do not fully understand how it works. Most people turn on the tap and expect the water to be there, but they never give any thought as to how it gets to your home. Here are the basics of the groundwater extraction process.

Drilling the Well

The first part of the process involves drilling a well. For this step in the process, you have to hire a certified well driller. The driller will come into the property and determine the most appropriate place for locating the well. In most cases, the well should be drilled on the highest ground, as this helps eliminate the chances of drilling into a contaminated water source. The well driller will use a large well drilling bit to drill down into the ground. For the uppermost part of the well, they will insert a metal tube known as a well casing. This is designed to help keep the well from caving in at the softest part of the ground. Once they get down into the lower layers of the well, they may be able to avoid using casing if the well is surrounded by rock. The well driller will stop when it is determined that the well is down in an aquifer that will provide an adequate source of water for the well.

Installing the Pump

After a well is drilled, the well owner has to install a water pump system to extract the water. For this part of the process, they will use a large pump truck with a powerful wench on an adjustable boom. The installer will attach a water pump to an electrical cable as well as to a pipe. The top of the pipe is attached to a clamp that is lifted by the wench on the truck. 

Then, the installer lowers the pipe with the pump attached to it down until the top of the first piece of pipe is level with the ground. At that point, the installer can rest the weight of the pump and the pipe on the top of the well casing. They will, then, attach a new piece of pipe to the wench and lift it up into the air. 

The new piece of pipe is attached to the one that is already in the well by using pipe wrenches. Then, the installer lowers the two pipes and the pump further down into the well. The installer continues using this process until the pump is far enough down into the water that it can pump up to the surface continuously. 

Finishing Up

Once the pump is down in the well, the installer will set up the system so that it can pump water. The electrical cable has to be wired into a control box. The pipe is then hooked up to a water line that runs to the area that needs the water. When the user turns on the water, it will work in conjunction with a storage tank to turn on and off the pump through the control box. In this manner, water can be extracted from the ground as needed.
