Details methods of domestic wastewater treatment that are especially suitable in developing countries. The emphasis is on low-cost, low-energy, low-maintenance, high-performance systems that contribute to environmental sustainability by producing effluents that can be safely and profitably used in agriculture for crop irrigation and/or in aquaculture for fish and aquatic vegetable pond fertilization. waste stabilization ponds (WSPs), wastewater storage and treatment reservoirs, constructed wetlands, upflow anaerobic sludge blanket reactors, biofilters, aerated lagoons and oxidation ditches.

In order to meet the challenges of the International Drinking Water Supply and Sanitation Decade (1981-1990), and now Safe Water 2000, developing countries, together with international agencies and donor countries need to invest in their water supply and sanitation sector - this book is a contribution to that development. It is an introduction to low cost sanitation and how to install cheap, safe and effective sanitation systems. It covers the topic concisely and informatively, with illustrations and worked examples where appropriate. The author approaches the subject from the point of view...

Low-cost sewerage provides a practical solution to the sanitation needs of low-income areas. As a result of the rapid urban population growth, the demand for sewerage exceeds the resources of most high density urban areas in developing countries. Low-cost alternatives to conventional sewerage, such as settled sewerage and simplified sewerage, therefore need to be developed.
