Supervision
High quality, timely construction supervision should be emphasized.
What do we know?
Doyen (2003) states: “over-drilling is roughly inversely proportional to the degree of supervision of drilling operations”. The quality of drilling supervision, as well as authority is important. Some drillers complain about being supervised by inexperienced hydrogeologists who are just out of university. Others use their monopoly on knowledge to their advantage and exploit the situation. Unfortunately, degree courses in geology and hydrogeology do not provide their graduates with a solid foundation in drilling supervision. Kaduna State Ministry of Water Resources in Nigeria realised that they did not have sufficient competence to supervise their drilling programmes and invested in training (Adekile, 2007).
