An underground route to access groundwater is created by excavating or constructing the structure of a water well. This source of pure water can then be accessed via an electric submersible pump, a jet pump, a centrifugal pump, or a trusty handpump.

A well drilling rig – it sounds grand and intimidating, but they come in all sizes. From small enough to be carried on a pick-up truck, to ones that need an entire convoy of vehicles for movement. All of this depending on the depth and substructure the rig must penetrate.

Delving into the depths of the earth to discover a new water well is no easy task; it’s a complex process that requires expertise and takes into account numerous factors. From accounting for the depth and these various elements like the soil, water table, and type of pumping to be used – there is certainly plenty to consider when drilling a water well.

To begin drilling a water well, the depth must be determined first. To find this, we measure the static water level – the amount of water in the well when not being pumped – using either a tape measure or a well sounder. These tools give us an accurate measurement of the static water level, which is our starting point.

To ensure the successful drilling of the well, it is important to determine the nature of the soil. Sand, clay, and rock are the three major substrates that cover the terrain, each possessing distinct characteristics which necessitate consideration in advance of the procedure.

Of all the soil types out there, sand is undoubtedly the simplest to penetrate. Nonetheless, its instability issues can lead to potential danger when the water level decreases significantly. On the other hand, clay is steadier than sand, yet more demanding to drill, while rock exhibits a different kind of challenge – as it is the most challenging soil to penetrate – yet offering the added security of greater stability should the water level plummet.

After setting the soil’s depth and identity, the next step should involve locating the water table — the point at which the underground moisture reaches saturation. A water level indicator or soil probe are both suitable for this task.

After detecting the water table, the natural progression is to decide on a pump type. Submersible, jet, and centrifugal are the three primary categories of pumps available.

When drawing water from a well, the two most commonplace pumps are submersible and jet models. Typically powered by electric motors, submersibles are designed to operate entirely beneath the surface. Jet pumps follow a distinct approach, using a jet of water to generate suction and transport the resource up the well. A less common option is a centrifugal pump. It relies on a petrol engine to charge blades that draw the water up.

A necessary step after deciding on the correct type of pump is to start drilling the well. This is done with a drill bit which is firmly connected to the rig. Gradually, it is sent into the ground, and due to its rotation, it can break through the terrain.

As the bit digs deeper and deeper, it digs out a hole larger than its own diameter. This gap is referred to as the annulus; thanks to drilling fluid, it is able to remain intact despite the pressure aswell as keeping the drill bit lubricated.

As the drill bit continues its revolutions, the hole gradually expands. All the debris produced by the rotations is whisked away via the drilling fluid, which ferries it to the surface and clears it from the hole.

After the well had been bored to the appropriate depth, the pump was lowered into the depths and the wires that connected it to the energy source were connected. Once everything was arranged, the pump was activated and, presto chango, it began to draw water up from the depths of the hole.

Water can be kept both in a pressure vessel and a storage container. The pressure tank is employed to keep the liquid under constant pressure, so it is ready when needed. The containment vessel is used to store the water until it is needed.

After entering the container, the liquid is circulated to its destination: a private residence or commercial space, through a series of encasings composed of either PVC or polyethylene.

When it comes to making a well, the depth and soil type are not the only things to consider—water well drilling rigs are available in various sizes, tailored to fit each unique project. It’s important to pay attention to multiple components, including the water table, the depth of the well, the kind of soil, and the kind of pump necessary for completion.
