Summary

Design and Build Safe, Efficient Systems for Irrigation and Water SupplyWater Wells and Pumpsis a comprehensive guide to the essential theory and design of ground water structures, wells/tube wells, and pumps, with particular emphasis on problem solving and meeting the requirements of developing nations. It features thorough, up-to-date knowledge of the science and technology of water wells and pumps as well as allied appliances and applications.This authoritative desk reference outlines the construction, operation, and maintenance of water wells for irrigation and water supply. It also presents the development and testing of tube wells as well as a variety of pumps, both location-specific. Using SI units exclusively,Water Wells and Pumpsfeatures: Coverage of a variety of pumps, including those using nonconventional, environmentally friendly means Examinations of ground water recharge methods, well rehabilitation, and animal-powered water lifts Techno-economic evaluation of projects on wells and pumps References and problems at the end of each chapter for research and educational useSolutions for all problems related to designing secure, reliable systems Ground water resources development and utilization Hydraulics of wells Open wells Tube wells and their designs Development and testing of tube wells Rehabilitation of sick and failed tube wells Man- and animal-powered water lifts and positive displacement pumps Variable displacement pumps and accessories Centrifugal pumps Deep well turbine and submersible pumps Propeller, mixed flow, and jet pumps Applications of nonconventional energy sources in pumping
