Constructing, or repairing, boreholes requires specialized knowledge and technical expertise, much of which can be gained from the standard literature; but field operations in remote areas or in difficult conditions often require flexibility and imagination in avoiding and solving technical problems. This review is intended as a decision-making tool to assist in making cost-effective choices between borehole drilling methods, and in deciding whether to drill new boreholes or rehabilitate existing sites.
