5 Preface The growing volume of municipal wastewater resulting from the rapidly increasing world's urban population creates severe environment al and health hazards, such as uncontrolled flows of sewage-polluting surface and groundwaters, soil, and agrieultural products. Different technologies have been developed to prevent this type of environmental degradation, among which the use of land as a living filter for removing pollutants from wastewater is especially popular. This technology, which is based on the soil-vegetation complex, is a viable, environmentally sound and costeffective method for the disposal of wastewater. Irrigation is one of the main land treatment approaches, and as other land treatment methods (e.g. infiltration-percolation), it is considered an efficient method of waste disposal. Numerous publications provide information on different components of existing sewage disposal systems. However, wastewater should also be seen as an alternative source of irrigation water, especially in dry regions, where reclaimed wastewater is sometimes the only source of irrigation water for agricultural development. The increasing use of sewage effluent for irrigation is documented in many relevant publications, many of which are reviewed and diseussed in this book. The present volume describes the main components of effluent-soilplant systems necessary for the development of appropriate irrigationfertilization-cropping management systems and cites representative case histories recorded in Israel and elsewhere. Comprehensive information has been provided on the following topics: (1) sourees, treatment methods and properties of treated sewage effluent; (2) the main processes of different effluent constituents (e.g. salt, nutrients, trace elements, organisms) in soil-plant systems; (3) irrigation and fertilization management; and (4) irrigation systems for effluent irrigation. The objective of the book is to provide the reader with a comprehensive overview of the principles and practices of using sewage effluent for irrigation. Although all aspects of irrigation management are diseussed, special attention is given to the praetices required to overcome the specific limitations imposed by the quality of the water, i.e., pathogenic microorganisms, high salinity and sodicity, high nutrient eontent, and under specific circumstanees, the presence of toxie levels of microelements, organic pesticides, and suspended solids.

6 VI Preface The book is not intended to be a comprehensive scientific review of published literature related to effluent irrigation, although major contributions in this field have been cited. Naturally, we have relied heavily on the Israeli experience to provide examples and demonstrations of some of the ideas and principles. The book is intended especially for the field irrigation manager (agro~omists, engineers and farmers), but it can also be used as a general reference for students and other specialists interested in the use of sewage effluent for irrigation. The reader will find valuable information on soil and plant processes taking place in the irrigated field, and on management methods suitable for effluent irrigation. The authors greatly appreciate the help of Mrs. Shulamit Gordon for her skillful and patient typing of the manuscript. We would also like to express our appreciation to our colleagues in the Institute of Soils and Water, ARO, The Volcani Center, Israel for their constructive suggestions during the preparation of the manuscript.
