Water for the Thousand Millions focuses on the distribution of safe water through effective water supply technology. This book discusses developments in the intermediate technology of water supplies such as rainwater catchment tanks, water conservation techniques, small solar distillation plants, and wind-pump projects. The topics discussed include water supply objectives and criteria of appropriateness; technically appropriate water supplies; socially appropriate water supplies at village level; and economically appropriate water supplies. This book is a good source for students and researchers conducting work on environmental science, specifically on water supply technology.
