2 Introduction In Nigeria, most rural and semi urban communities are dependent on groundwater supplies This makes water well drilling, rig fabrication and borehole supervision popular, very relevant, and profitable Reported cases of borehole failures resulting from inadequate sitting to poor construction which can be attributed to lack of professionalism exhibited by some Hydrogeologists, Drillers, rig fabricators and supervisors or Consultant due to poor or limited capacity 2 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

3 Need for Capacity Building In view of this, a lot of attention has been given to scaling up capacity development in the drilling sector in the past few years. National Water Resources Institute (NWRI) in institutional assessment to identify capacity gaps in the drilling areas and efforts carried out to improve drilling activities through various training programmes at different levels of drilling industry and provides a guide for achieving better capacity development in the industry towards drilling of sustainable boreholes in the country with improved economic impact. 3 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

14 Strategies for building capacities in the drilling industry Capacity development of Nigerians by the NWRI to manage and develop the drilling industry has been through the following: Regular Courses: These are regular training courses lasting 12 to 24 months duration (Advanced Diploma in Hydrogeology) Short Courses: Skill development training courses for short duration (1 day to 4 months. Eg. Drilling Technology, borehole drilling, design and construction, borehole maintenance and rehabilitation, groundwater geophysical techniques, rig fabrications, handpump installation and maintenance. Outreach Courses: These are demand driven and on-the- job training courses (2 days to 2 weeks) Project Specific Trainings: Demand driven and integral parts of borehole projects (2 days to 2 weeks) Table Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

22 Standardization of Water well drilling rigs fabrication The Institute has supported the standardization of water well drilling rigs fabrication locally. Field assessment visits were carried out to most local rig fabrications workshops in different part of Nigeria. It was noted that fabrication of water well drilling rigs locally is an active business in Nigeria. However these fabrications are faced with challenges, such as sourcing rig components particularly power heads, hydraulic pumps, control valves, hydraulic jacks, prime movers, and adequate steel strength for most construction. The Institute is in partnership with the National Agency for Science and Engineering Infrastructure (NASENI) to design, product and test these components 22 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

23 Rig Fabrication Training (9 months) To support the capacity of our youths on local rig fabrication, Developed training for unemployed Nigerian Youths who have background in science, engineering or technology. The main objective of this programme is to create jobs, reduce poverty and empowers Nigerian youths in line with the transformation agenda of the Federal Government of Nigeria. The locally fabricated rigs will enable government and citizens spend less money on borehole drilling and other water well projects in the country 23 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

24 Trainings on Rig fabrication cont. The major course contents include: Elements of drilling design and features of drilling rigs; basic geology and fundamentals of Water Well drilling; Hand tools and machine tools; Welding processes and Workshop practice; Material selection and Motion/Power components of rigs; Internal Combustion Engines; Hydraulic and Pneumatic systems; Business Organization and Entrepreneurship; and rig assembly 40 participants have been trained. Presently 15 youths are on the same training at the Institute. 24 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

26 Provision of platform for knowledge sharing The National conference annually organized by the NWRI, other Seminars, Workshops and Symposium Nigeria Association of Hydrogeologist, Nigeria Mining and Geosciences Society and AWDROP organize annual conferences COMEG Annual professional training programmes 26 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

27 Development of National Codes of Practice for Water Resources Development and Management The Institute has identified the drilling area as priority and have developed a Code of Practice for water well construction in Nigeria that will address the various challenges militating against poor borehole failures in Nigeria Code of Practice for drilling rig fabrication is the next in the drilling sector 27 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

28 Economic Impact A very vibrant and sustainable drilling industry in Nigeria is expected to increase gains for the individuals that are trained in the drilling skills and reduce borehole failures and increase access to water supply and sanitation facilities for rapid and economic growth of the economy The impacts will also entails more availability of drilling rigs and reduce cost of borehole in general and more people will be served with portable water and good health for overall economic growth of the Nigeria economy. 28 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

29 SUMMARY /CONCLUSION The impact of capacity building for the enhancement of the drilling sector has been reported and the benefits outlined. Capacity gaps in the drilling industry has been identified through Institutional Assessment Codes of Practice for Water Well Construction in Nigeria has already been developed and approved. The Institute is currently in the process of developing code of practice for Water Well Rig Fabrication. Finally, the there are substantial economic impact resulting from effective training and research in the drilling – reduced unemployment and economic enhancement 29 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria

34 Recommendations Training and retraining of drillers. All Drillers should continue to develop themselves through re- training programmes on a regular basis. Need for provision of credit facilities. Bank of Industry and other banks should give regular credit facilities at reduce interest rates for Drillers and Rig owners to assist them in procurement of their machinery. Institutionalization of Certificates Issued by the National Water Resources Institute for professional promotion. This will ensure training and retraining 34 Capacity Enhancement of Water Well Drilling Operators for Economic Impact in Nigeria
