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...
