Water distribution systems are made up of pipe, valves and pumps through which treated water is moved from the treament plant to homes, offices, industries, and other consumers. The types of materials and equipment used by each water system are usually governed by local conditions, past practices, and economics. Consequently, drinking water professionals must be knowledgeable about common types of equipment and operating methods that are available. Completely revised and updated, Water transmission and distribution includes information on the following: distribution system design and operation and maintenance ; piping materials ; valves, pumps, and water meters ; water main installation ; backfilling, main testing, and installation safety ; fire hyfrants ; water storage ; water services ; cross-connection control ; motors and engines ; instrumentation and control ; information management and public relations.--Cover page [4].

Prepared by the Water Supply Engineering Technical Committee of the Infrastructure Council of the Environmental and Water Resources Institute of ASCE. This report provides a comprehensive survey of the state of the art in drinking water treatment methods and technologies for controlling microorganisms. Academics, practicing engineers, and environmental scientists offer insight into the risks posed by microbes in drinking water and ,more importantly, their control through treatment and disinfection. The report supplies an overview of the subject for nonspecialists and becomes a valuable technical reference for experienced practitioners. Topics include: Ørisks posed by pathogens in drinking water; Ømicrobially-mediated corrosion and water quality deterioration; Øindicator concept and its application in water supply; Øremoval of organisms by flocculation/sedimentation; Øair stripping and aeration; Øslow sand filtration; Ørapid sand filtration; Øgranular activated carbon/biological activated carbon; Øcontrol of microorganisms in drinking water by pressure-driven membrane processes; Øgeneral kinetics of disinfection processes; Øchlorine and chloramines; Øchlorine dioxide in drinking water treatment; Øultraviolet disinfection; Øozone disinfection in drinking water; and Øemerging pathogens of concern in drinking water.

In many regions of the world, water is scarce. This causes a problem in plant production, as plants rely on water stored in the soil to meet their needs; thus it is the principal factor limiting crop production.Water Dynamics in Plant Production describes the basic scientific principles of water transport in the soil-plant-atmosphere continuum, explains the linkage between transpirational water use and dry matter production and presents various agronomic strategies to adapt to climate water shortage.

This brand new manual was written because of the increased use of chloramine as a residual disinfectant in drinking water distribution systems and the ubiquitous presence of nitrifying bacteria in the environment. Chapters cover background information on the occurrence and microbiology of nitrification in various water environments and provide current practical approaches to nitrification prevention and response. This manual provides a compendium of the current state-of-the-art knowledge, however with quickly developing new advances in nitrification, more writings will be forthcoming. Each chapter can be read independently.

This book deals with environmental effects on both sides of the border between Bangladesh and India caused by the Ganges water diversion. This issue came to my attention in early 1976 when news media in Bangladesh and overseas, began publications of articles on the unilateral withdrawal of a huge quantity of water from the Ganges River through the commissioning of the Farakka Barrage in India. I first pursued the subject professionally in 1984 while working as a contributor for Bangladesh Today, Holiday and New Nation. During the next two decades, I followed the protracted hydro-political negotiations between the riparian countries in the Ganges basin, and I traveled extensively to observe the environmental and ecological changes in Bangladesh as well as India that occurred due to the water diversion. The Ganges, one of the longest rivers of the world originates at the Gangotri glacier in the Himalayas and flows across the plains of North India. Eventually the river splits into two main branches and empties into the Bay of Bengal. The conflict of diversion and sharing of the Ganges water arose in the middle of the last century when the government of India decided to implement a barrage at Farakka to resolve a navigation problem at the Kolkata Port.
