The Collection of Rainfall and Runoff in Rural Areas.
Clearly illustrated details for building rainwater catchment and water storage tanks with locally available materials. Oriented for people in developing countries but excellent information for anyone needing more water. Great hope for the thousands of scattered, small communites in semi-arid countries not served by centralized water. Case studies of work in Africa, India, and Southeast Asia.
