| Popis: | Groundwater development through construction of water wells forms the nuclei of government and international donor agencies intervention programmes in the rural and semi-urban areas. These wells are drilled using hand-digging, human powered drilling rigs, imported and locally fabricated small and large conventional drilling rigs. The efforts of indigenous rig fabricators have improved access to water in Nigeria, but their equipment majorly lacking in engineering design soon breakdown after commissioning. While they work, their operations are usually cumbersome and stressful with random breakages of drill stems and drill bits. The trend has persisted to the degree that progress in water prospecting has become the race of three steps forward and four steps backwards. The National Board for Technology Incubation and the Hydraulic Equipment Development Institute both of the Federal Ministry of Science and Technology, in keeping with their intersecting mandates of bringing technology to the grassroots and developing hydraulic machines respectively; in 2011, instructed this project in the following terms: "By reviewing existing human powered drilling methods, develop a more efficient technology with reduced human horsepower requirement capable of achieving up to 50meters depths in the low depth aquifers scattered across the country." |
