Balanced, broad-based, and up to date, this comprehensive text explores the nature and critical issues of earth resources and the impacts that resource usage has on the earth environment. The authors offer full coverage of all major types of earth resources-energy, metallic, nonmetallic, water, soil. A minimal scientific background is assumed.

"Small-scale Water Supply" provides non-specialists with an overview of the technologies available for water supply in low-income communities in rural areas of developing countries. Focusing chiefly on "point supplies" such as wells, boreholes, springs and rainwater catchment systems, the book also introduces the reader to powered pumps, water treatment and piped distribution systems. Chapters cover design capacity, sources of water, raising water, storage and water treatment. The book contains useful illustrations of each of the technologies and outline guidance on making appropriate choices between technologies. The subject of water supply is vast and this handy book shows the reader where to begin in designing water supply systems. Extensive appendices point the reader to sources of further information for each technology, both in printed form and from Internet web pages.Published in collaboration with WELL (Water and Environmental Health at London and Loughborough).
