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.

Yes ; Building roofs represents a critical pathway for sediment mixing with rainwater. This study aims to explore the correlation between roof-top deposited sediment matter in the different areas of the Ikorodu Local Government Area in Lagos, Nigeria. The deposition rate on the roof was studied for 34 weeks in total (i.e., 17 weekly analyses in the rainy season and 17 weekly analyses in the dry season). The total deposition was collected by a 10 inch funnel and directed into a 5 L container, which was partially filled with sterilised water. The roof-top deposition in four different areas was inspected and analysed. The four areas were selected based on the levels of sanitation and vege-tation. The experimental results showed that the enumerated total depositions in different areas were higher in the dry season than the rainy season, with the highest deposition occurring in the Harmattan period. The data obtained from this study have evidenced that the contamination from roof-harvested rainwater can mainly be attributed to atmospheric deposition. Another key factor was the hygiene and sanitation of the harvesting areas, including the gutter, pipes and proximity to animal faeces.
