This second edition of the classic title on practical energy provision for isolated houses and remote locations has now been updated with a new chapter. Pumps as Turbine is a practical handbook for engineers and technicians involved in designing and installing small water-power schemes. It concerns the use of standard pump units as a low-cost alternative to conventional turbines to provide stand-alone electricity generation for isolated houses and remote communities. This second edition has been updated and extended to include a case study from a recent scheme installed in collaboration with ITDG Kenya. The pump selection process is described through this step-by-step example, where the site head would have been too low for a Pelton turbine. The case study demonstrates that now, possibly more than ever before, the use of pumps as turbines offers a reliable, low-cost option for rural electrification. Arthur Williams has been involved in micro-hydro research and development since 1987. While completing his PhD he worked with ITDG to set up successful pump-as-turbine demonstration schemes in the UK and Pakistan. He is now a senior lecturer at the Nottingham Trent University where he continues to work on micro- and pico-hydro power.

This book provides users, pump manufactures, engineers, researchers and students with extensive information about pump’s behavior in reverse operation. It reports on cutting-edge methods for selecting the proper PAT and improving PAT’s efficiency, discusses PAT’s reliability, economic issues and environmental impact as well. The book describes in detail electromechanical equipment of PAT systems, their installation and operation, and gives important practical insight into the use of PAT in water transmission and distribution systems, as part of thermal power plants and cooling systems, in oil distribution systems and other systems as well. It reports on different types on PAT control modes as well as on numerical methods useful for PAT analysis and implementation. All in all, the book represents a comprehensive practice-oriented reference-guide to design engineers, as well as PAT general users and manufactures. It also provides researchers with extensive technical information on the use of PAT thus fostering new discussions and ideas to improve current methods and cope with future challenges.
