The process of drilling a borehole will depend on the factors above and the geology experience of the drilling professionals.
It can be very expensive if the operator is not very experienced and could lead to mistakes, wasteful materials and it can be time consuming to do geology research on the site.
It is also important to factor in the purpose of the borehole. Every type of borehole will have different methods, materials and manpower needed. For example, drilling different type of boreholes for example, a bottling plant, commercial site, residential site or a borehole for animals.
Another thing that is important to keep in mind when calculating the price of a borehole is how much water is needed and for how long it is intended to use the borehole. Some boreholes can be used for only a few years, where others can last for decades to come.
