The Benefits of Borehole Drilling: Why You Should Consider It : Introduction      T o have a ccess to clean and reliable water is a fundamental human need. There are i ncreasing concerns about water scarcity, water pollution, and  limited government water  supply  in many areas.As to this effect,  borehole drilling has become an attractive /alternative  solution for individuals, communities, and businesses  for sustainable water supply. Benefits of Borehole Drilling 1.  Reliable Water Supply : A personal borehole is unaffected by government   water supply disruptions or water restrictions and thus   serves as  a consistent and reliable source of water . 2.  Borehole   Increase s  Property Value : A good borehole can significantly increase your property value, making it more attractive to potential buyers. 3.  Clean and Fresh Water : Naturally, b orehole   water is  filtered as it passes throug...

Borehole drilling methods: There are few borehole drilling methods but we will base our discussing on two important and most widely used methods of drilling a borehole 1.  Rotary Drilling: This is about the m ost common method for water borehole drilling .This method u ses a rotating drill bit   attached to a drill pipe  to drill through the earth’s subsurface.This method can be used  for deep ,shallow  and large-diameter   boreholes   Drilling fluid , mud or water  (along side chemicals ) is used to remove cuttings and stabilize the borehole . 2.  Down-the-Hole Hammer (DTH) Drilling: T his drilling method Combines rotary and percussion method of drilling . This method is done by using  a hammer / drill bit inside the borehole Unlike the rotary method,this method is more effective for drilling hard rock formations .this method is c ommonly used for deep water boreholes  for both domestic and industrial use 3.  The use of manual...

What is a borehole A borehole is a vertical hole drilled into the earth's subsurface for the purpose of obtaining usable water for domestic and industrial purpose What is borehole drilling for water exploitation   Borehole drilling is the process of creating a vertical hole down into the ground or earth to access water from the subsurface. Borehole drilling process involves the use of specialized equipment to drill a hole into the earth's subsurface. The depth of a borehole i.e. how deep a borehole is can range from a few metres to a few hundreds of metres deep.   Borehole drilling process   1. Pre-Drilling/Preparation Phase   Siting and point  selection : This means to Identify a suitable location for a borehole drilling through geophysical surveys and/ or hydrological surveys.   Documents and permitting: Obtain the necessary documents, permits and approvals from local authorities and associations regulating drilling activiti...
