The purpose of the Commercial and Industrial End Uses of Water study is to: Summarize and interpret the existing knowledge base on commercial and institutional (CI) uses of utility-supplied potable water in urban areas; Present the results of field studies in a sample of 25 establishments in five urban areas; Provide econometric end use models for various categories of CI customers; and Develop a set of efficiency benchmarks for five important CI categories - restaurants, hotels and motels, supermarkets, office buildings, and schools.

The American Water Works Association Research Foundation (AWWARF) and 22 municipalities, water utilities, water purveyors, water districts and water providers funded this study. Goals of this research included: Providing specific data on the end uses of water in residential settings across the continent; Assembling data on disaggregated indoor and outdoor uses; Identifying variations in water used for each fixture or appliance according to a variety of factors; and Developing predictive models forecast residential water demand. This report represents a time and place snapshot of how water is used in single-family homes in twelve North American locations. Similarities and differences among 'end users' were tabulated for each location, analyzed and summarized. Great care was taken to create a statistically significant representative sample of customer for each of the twelve locations. However, these twelve locations are not statistically representative of all North American locations.

Water Management Challenges in Global Change contains the proceedings of the 9th Computing and Control for the Water Industry (CCWI2007) and the Sustainable Urban Water Management (SUWM2007) conferences. The rationale behind these conferences is to improve the management of urban water systems through the development of computerbased methods. Issues such as economic globalisation, climate changes and water shortages call for a new approach to water systems management, which addresses the relevant technical, social and economic aspects. This collection represents the views of academic and industrial experts from a number of countries, who provide technical solutions to current water management problems and present a vision for addressing the global questions. The themes underlying many of the contributions include energy and material savings, water savings and the integration of different aspects of water management. The papers are grouped into three themes covering water distribution systems, sustainable urban water management and modelling of wastewater treatment plants. The water distribution topics cover asset and information management, planning, monitoring and control, hydraulic modelling of steady state and transients, water quality and treatment, demand and leakage management, optimisation, design and decision support systems, as well as reliability and security of water distribution systems. The sustainable urban water management topics include urban drainage systems, water reuse, social aspects of water management and also selected facets of water resources and irrigation. Computer control of wastewater treatment plants has been seen as less advanced than that of clean water systems. To address this imbalance, this book presents a number of modelling techniques developed specifically for these plants. Water Management Challenges in Global Change will prove to be invaluable to water and environmental engineering researchers and academics; managers, engineers and planners; and postgraduate students.

Showing professionals how to produce a long-term Integrated Resource Plan for their water utility, this comprehensive manual covers such topics as estimating future water demand, evaluating new sources of water, involvement of stakeholders in the planning process, and dealing with expanding environmental regulations.

This Manual of Water Supply Practices provides utility guidance on how to develop an integrated resource plan for ensuring adequate water supplies to accommodate projected future water demands. Covers all topics of water resources planning: demand forecasting, evaluation of potential new source waters, hydrologic modeling, regulatory issues, environmental impact analysis, public involvement, and economic analysis. Includes sample Integrated Resources Plans developed by water utilities.
