The supply of reliable and safe water is a key challenge for developing countries, particularly India. Community management has long been the declared model for rural water supply and is recognised to be critical for its implementation and success. Based on 20 detailed successful case studies from across India, this book outlines future rural water supply approaches for all lower-income countries as they start to follow India on the economic growth (and subsequent service levels) transition. The case studies cover state-level wealth varying from US$2,600 to US$10,000 GDP per person and a mix of gravity flow, single village and multi-village groundwater and surface water schemes. The research reported covers 17 states and surveys of 2,400 households. Together, they provide a spread of cases directly relevant to policy-makers in lower-income economies planning to upgrade the quality and sustainability of rural water supply to meet the Sustainable Development Goals, particularly in the context of economic growth.

Richard Carter weaves together the myriad of factors that need to come together to make rural water supply truly available to everyone. He concludes that ultimately, systemic change to the global web of injustice that divides this world into rich and poor may be the only way to address the underlying problem.

A comprehensive and up-to-date account of filtration in solid-liquid separation processes, with a sharp focus on the influence of pro-cess variables on performance and specific applications is pre-sented in this volume. With contribu-tions from researchers with significant industrial experi-ence, as well as by senior academics, this publication fea-tures a deep bed filtration overview with informa-tion on mathematical modeling and application in wastewater treat-ment. Pre-treatment filtration techniques such as cartridge filters, pre-coat filters and micro screening are included. Membrane filtration processes to remove dis-solved and suspended solids for the recovery of valuable ma-terials and the provision of high quality water are covered. Sludge de-watering methods such as centrifuga-tion, and vacuum and pressure filtration are described. Application status data, tables, figures and diagrams are also included. This volume is of special interest to practicing engineers and technolo-gists dealing with treatment problems requiring filtration solu-tions and to graduate students in environmental engineering.
