Intended for professionals, administrators or engineers, project managers or policymakers and trainers or workers in the field of health, water and sanitation, this book brings together a series of short and illustrated introductions to the main technologies and processes in the field of village and community level water and sanitation. Developed and tested over the years, the 32 "appropriate technologies" described here range from household water storage to public standposts, from making soap to eye and skin diseases. Each short brief concludes with an indication of where to go for more information, and Professor John Pickford sets the scene for the programme and project workers who will find this "ideas tank" invaluable. Originally published individually in "Waterlines", a magazine devoted to low-cost water and sanitation, this consolidated publication brings together a body of practical information and guidance which appropriately marks the end of the "Water Decade" and the start of the "Health for All by 2000" campaign.
