Water wisdom

This book draws on the author's life-long experience working in the family firm Guthrie Allsebrook & Co. Ltd., both in the United Kingdom and in developing countries. The book is divided into 14 chapters, focusing on low-cost technologies. The initial chapters are on the water cycle and hydrogeology. The next two chapters provide case studies and practical advice on dug wells, driven tubewells, and boreholes. There are six short chapters on pumps, outlining the different types of pumping methods with their applications, including air pumps, the hydraulic ram, and wind pumps. There are chapters on storing water and on basic water treatment, and a longer chapter on irrigation with three relevant appendices. The final chapter, entitled "Water for fun", gives case studies on fountains and other ornamental features. There is also a brief appendix on the history of the family firm.
