Household Reusable Rainwater Technology for Developing and Under-Developed Countries provides insight into household techniques for collecting and treating harvested rainwater safely for both potable and nonpotable uses, as well as practices to improve its quality, with numerous realworld case studies and data. It gives a comprehensive, holistic account on the household scale for both developing and under-developed countries. Improvement mechanisms such as the impacts of first flush, household water treatment techniques, and sedimentation in the harvested water are described in depth together with the advantages and disadvantages of their common practices in developing and under-developed societies. Also discussed is a comprehensive survey illustrating the impact of rainwater sources on the daily life of a carefully selected community from the perspective of its residents. The book is ideal for students, researchers, academics, water policy providers, and bodies worldwide such as WHO and DFID.
