africa water well drilling

Africa boasts a wealth of highly-sought water well drilling services, and the companies providing such services come with a range of individual techniques and costs.

A hand-dug approach remains the most commonly used method for water well drilling in Africa. By assembling a team of workers, a manual excavation process is employed which continues until a replenishing source of water is attained. The depth of this nature-made well is reliant upon the proximity of the underlying water table.

Making use of a specialized machinery, the rotary drilling method is one of the most sought-after techniques employed in drilling holes. The machine sports a revolving drill bit that penetrates the rock, creating a hole as deep as the underground water table.

Uncovering groundwater isn’t always simple, however the third most preferred solution is cable tool drilling. In this method, instead of a spinning drill, a cable is manipulated to penetrate through the rock. The extent of the drilled opening varies depending on the water table’s depth.

To access the water table and depths that lie beneath its surface, the submersible pump drill method is employed as the fourth most frequently employed technique. This innovative approach involves using a device to bore into the earth, but replacing the customary spinning drill bit with a submersible pump. By leveraging the flood of liquid from the pump, one is able to determine the true profundity of the well; determined solely by the depth of the temperature.

A unique technique for drilling holes called airlift drilling is ranked fifth in popularity. The process involves a machine that directs the excavation, however, instead of a typical drill bit, an airlift is employed to push liquid upward. Exactly how far below ground the airlift goes is contingent on the level of water in the underground reservoir.

Drilling with a jet of water is the sixth-most-utilized methodology, whereby a powerful spray of liquid is employed instead of a standard rotating bit. This method can reach depths based on the placement of the water table, with no limit to how far it can probe.

To reach further depths, the seventh-most employed technique is reverse circulation drilling. A machine drills a hole and, contrary to traditional methods, utilised a reverse circulation to transport the drilled residue to the surface. The depths of the borehole differ depending on how far underground the water table lies.

Instead of a rotating drill bit, a hydraulic fracture is applied to go beyond the water table by drilling a hole with the help of a machine. This procedure, referred to as hydraulic fracturing drilling, is the eighth mostly used method. Its depth is determined by how deep the underground water supply goes.

To penetrate deep layers of earth, a steam injection drilling technology is frequently employed. This entails employing a machine to dig a hole, instead of operating a rotating drill bit, steam is injected into the hole. The dimensions of the opening depend upon the depth of the water table.

Instead of the traditional drill bit, the tenth most popular technique for creating an opening relies on the utilization of electricity. This electro-kinetic drilling method uses a machine to apply electrical power and cut through rock, tuning the depth of the hole based on how deep the water table is located.
