Utilizing powerful rotary drill bits, the process of water well drilling involves burrowing a hole in the ground to access groundwater. This task is achieved with a specialized drill rig that utilizes a drill string comprised of a drill bit, collar, and drill pipe. The drill bit is the part that does the actual cutting, while the collar and drill pipe are two welded pipes situated above and below it respectively. All components embodied within the drill string work together to form a successful water well.

For boreholes of differing depths, water well drilling rigs are available in a diverse array of shapes and sizes, be they mounted on trucks or trailers. The chosen rig is directly proportionate to the amount of drilling needed.

Drilling for shallow wells (any wells that decrease to a depth of 500 feet or less) often requires a truck-mounted rig, however, those wishing to allocate funds for deeper wells will need to purchase a trailer-mounted unit. As the depth of the well increases, so too does the cost of the required rig.

In order to drill a water well effectively, it is crucial to consider a combination of factors in order to identify its most suitable location. This includes analysing the geological composition of the terrain, determine the depth of the local water table, and taking into consideration neighbouring wells.

Having established the well’s position, the subsequent action is to identify the proper drill bit for the job. What model needs to be employed hinges on the sort of rock that needs to be perforated.

To bore through softer types of rock, such as sandstone, the most commonly deployed drill bit is the roller bit. Comprised of many small cone-like cutters that spin when the drill string is turned, the roller bit readily will cut through the soft levels.

After the setup is complete, it is time to begin boring. With the drill rig in the proper place, the string of drills is lowered into the well. Once activated, the drill bit stirs up a flurry of activity, burrowing its way through the rock. As it rotates, the drill string creates a deep pit in its wake.

As the Drill String ascends from the abyss, it brings with it an array of cuttings which are analysed to determine the composition of earth that lay beneath.

Having finished piercing the well, a tubular barrier, commonly known as the well casing, is secured into the inner walls of the excavated crevice. This casing acts as a shield that safeguards the safety of the well from possible caving during later use. It also helps to keep out any surface runoff or extraneous material from entering and polluting the borehole.

Down into the depths, a well casing is set in motion. A device known as a casing hammer is used to ensure that this steel or PVC pipe placement finds its mark and is perfectly secured. It lowers over the pipe and, with calculated strength, drives it down into the awaiting hole.

Once the well casing has been carefully situated, the next stage is to mount the well screen. This internal element of the construction, a mesh-like tube with perforations, allows water to flood into the well while preventing any sand or surplus particles from infiltrating into the structure.

To form a well, the PVC pipe of the well screen must be carefully fitted within the borehole. For this, usages of a tool known as a screen driver is required, which is first inserted into the opening. Once settled, the screen driver is used to press the well screen down into its place.

After the well screen has been securely situated, the next course of action is to deploy the submersible pump. This tool is situated within the well and is responsible for delivering water up to land level. Essentially, this pump supplies useable water from down in the well.

Crafted from stainless steel, the submersible pump requires the usage of a pump hoist to be descended into the desired hole. This device is placed on top of the said pump before carefully lowered into the depths of the designated area, allowing the motorized implement to find its exact spot in a precise and effective manner.

Upon successfully positioning the submersible pump, the next transition is to attach it to a fuel supply. An electric motor or a gasoline engine are both suitable alternatives – depending on the circumstances. Then, that is all there is to it – simply switch the pump on and bingo! You have successfully pumped water up from the depths of the well to ground level.
