As interest in the provision of decentralized electricity in the South increases, this practical handbook is as important as ever.

'Pumps as Turbines: A user’s guide' is a practical handbook for engineers and technicians involved in designing and installing small water-power schemes for isolated houses and communities. It concerns the use of standard pump units as a low-cost alternative to conventional turbines to provide stand-alone electricity generation in remote locations.

This book arises out of the practical experience of fieldwork in village locations in a number of countries.

This new edition includes a brand new chapter featuring a case study of a PAT (pump-as-turbine) installation. It covers how to select the type of pump based on site requirements, potential pump modifications and caution with single-phase pumps.
