Through ancient history, accessing the liquid gold of the land was possible only through manual digging. From at least 8 thousand years ago, water wells provided a way for humans to withdraw groundwater from aquafers underground, granting people access to life’s most necessary resource. This process was primarily done by hand, but over time, the process evolved, eventually leading to the invention of specialized machinery which could extract water from depths of thousands of feet below the surface. Today, electric submersible pumps, jet pumps, centrifugal pumps and handpumps are all employed in getting water up from the depths- granting human lives sustenance without a moment’s thought.

The responsibility for water well construction in the US is primarily delegated to state governments, with federal jurisdiction being strictly confined. The EPA, acting as a watchdog, manipulates certain criteria of safety for drinking water wells in the nation. However, the governing body holds no authority over irrigation and monitoring wells.

From the assessment and approval of a suitable well site to the completion of the drilling process, the journey of constructing a water well necessitates a vigilant selection procedure. Factors such as the usage of well water, local geology, and access to utilities and other infrastructure are important considerations for choosing the ideal spot to build the well. With the site chosen, a professional well driller is called upon to commence their expertise and fulfill the task.

The well-drilling process begins with the excavation of a hole to house the casing pipe that will make up its walls. This pit is usually drilled using a rotary drill bit. The well casing serves two purposes; first, it provides a guard against loose earth, and second, it helps draw the water from the well to be used as desired.

After the drill is used to make the necessary hole, the well casing is inserted. Steel is generally used for this feature; however, PVC can also make its way onto the scene. To secure the casing in its spot, it must be carefully lowered into the excavated cavity and held secure with cement.

Once the protective casing is put in its place, the well must be bored out. A rotary drill bit is connected to a drill tool through a drill pipe, and the rig is what spins it around to carve an opening for access to the well. As it whirls, it chips away the earth and stone, producing a tunnel for the well.

To ensure the well is primed to receive fresh water, a screen is set into place. This specialized pipe is marked with tiny perforations made specifically for water to flow in, while simultaneously acting as a protective barrier from any sand or other sediment particles.

After the well is bored, the water is drawn forth. Three kinds of pumps are often used for this purpose: an electric submersible pump, a jet pump, and a centrifugal pump.

Supplying a lifeline of refreshment, wells are an indispensable part of mankind’s infrastructure, consistently providing us with a secure source of water for consumption, irrigation, and more. In various parts of the globe, these havens of hydration are a crucial source of such an essential resource.
