A Low-Cost Indigenous Intervention which has Revolutionized the Drilling Technology and Changed the Life of Millions of Farmers in the State of Uttar Pradesh, India

摘要

An unknown indigenous driller combined the percussion and circulation drilling principles, resulting in the development of low cost, low weight manual boring set in the year 1990-1991/1991-1992, which revolutionized the shallow well drilling technology and made possible to drill about 4.5 million shallow bore wells in the State. This has changed the landscape of irrigated agriculture, changing the life of millions of small and marginal farmers and contributed a lot in increasing crop production and crop productivity. The developed drilling equipment locally known as "Pressure Boring Set" is manually operated, low cost and can be transported on bicycles. Drilling cost is also less. This low cost and simple technology made it possible to drill large number of shallow bore wells in comparatively short time span and less cost, consequently enhancing the rate of increase in irrigated area and in turn crop production and productivity. Cost of the boring set is also low, as compared to traditional sand pump hand boring set and suitable for alluvial areas.
