In the quest to reduce costs and improve the efficiency of water and wastewater services, many communities in the United States are exploring the potential advantages of privatization of those services. Unlike other utility services, local governments have generally assumed responsibility for providing water services. Privatization of such services can include the outright sale of system assets, or various forms of public-private partnershipsâ€"from the simple provision of supplies and services, to private design construction and operation of treatment plants and distribution systems. Many factors are contributing to the growing interest in the privatization of water services. Higher operating costs, more stringent federal water quality and waste effluent standards, greater customer demands for quality and reliability, and an aging water delivery and wastewater collection and treatment infrastructure are all challenging municipalities that may be short of funds or technical capabilities. For municipalities with limited capacities to meet these challenges, privatization can be a viable alternative. Privatization of Water Services evaluates the fiscal and policy implications of privatization, scenarios in which privatization works best, and the efficiencies that may be gained by contracting with private water utilities.

This book reviews the practice of reclaiming treated municipal wastewater for agricultural irrigation and using sewage sludge as a soil amendment and fertilizer in the United States. It describes and evaluates treatment technologies and practices; effects on soils, crop production, and ground water; public health concerns from pathogens and toxic chemicals; existing regulations and guidelines; and some of the economic, liability, and institutional issues. The recommendations and findings are aimed at authorities at the federal, state, and local levels, public utilities, and the food processing industry.

The principle of the conventional activated sludge (CAS) for municipal wastewater treatment is primarily based on biological oxidation by which organic matters are converted to biomass and carbon dioxide. After more than 100 years’ successful application, the CAS process is receiving increasing critiques on its high energy consumption and excessive sludge generation. Currently, almost all municipal wastewater treatment plants with the CAS as a core process are being operated in an energy-negative fashion. To tackle such challenging situations, there is a need to re-examine the present wastewater treatment philosophy by developing and adopting novel process configurations and emerging technologies. The solutions going forward should rely on the ways to improve direct energy recovery from wastewater, while minimizing in-plant energy consumption. This book begins with a critical overview of the energy situation and challenges in current municipal wastewater treatment plants, showing the necessity of the paradigm shift from removal to recovery in terms of energy and resource. As such, the concept of A-B process is discussed in detail in the book. It appears that various A-B process configurations are able to provide possible engineering solutions in which A-stage is primarily designed for COD capture with the aim for direct anaerobic treatment without producing excessive biosludge, while B-stage is designated for nitrogen removal. Making the wastewater treatment energy self-sustainable is obviously of global significance and eventually may become a game changer for the global market of the municipal wastewater reclamation technology. The principal audiences include practitioners, professionals, university researchers, undergraduate and postgraduate students who are interested and specialized in municipal wastewater treatment and process design, environmental engineering, and environmental biotechnology.

In December 2002, a group of specialists on water resources from the United States and Iran met in Tunis, Tunisia, for an interacademy workshop on water resources management, conservation, and recycling. This was the fourth interacademy workshop on a variety of topics held in 2002, the first year of such workshops. Tunis was selected as the location for the workshop because the Tunisian experience in addressing water conservation issues was of interest to the participants from both the United States and Iran. This report includes the agenda for the workshop, all of the papers that were presented, and the list of site visits.

Close to one-half of all Americans live in coastal counties. The resulting flood of wastewater, stormwater, and pollutants discharged into coastal waters is a major concern. This book offers a well-delineated approach to integrated coastal management beginning with wastewater and stormwater control. The committee presents an overview of current management practices and problems. The core of the volume is a detailed model for integrated coastal management, offering basic principles and methods, a direction for moving from general concerns to day-to-day activities, specific steps from goal setting through monitoring performance, and a base of scientific and technical information. Success stories from the Chesapeake and Santa Monica bays are included. The volume discusses potential barriers to integrated coastal management and how they may be overcome and suggests steps for introducing this concept into current programs and legislation. This practical volume will be important to anyone concerned about management of coastal waters: policymakers, resource and municipal managers, environmental professionals, concerned community groups, and researchers, as well as faculty and students in environmental studies.

A thorough analysis of public policy and the Clean Water Act'seffect on water quality in the U.S. Using water quality data and historical records from the past 60years, this book presents the measured impact of the 1972 CleanWater Act on domestic waterways-ecologically, politically, andeconomically. Municipal Wastewater Treatment supports thehypothesis that the Act's regulation of wastewater treatmentprocesses at publicly owned treatment works (POTW) and industrialfacilities has achieved significant success. The authors' case ispresented in: * Background information on the history of water pollution controland water quality management * Chapters addressing long-term trends in biochemical oxygen demandloadings from municipal wastewater plants and the "worst-case"dissolved oxygen levels in waterways downstream of point sourcesbefore and after the Clean Water Act * Nine case study assessments of long-term trends of pollutantloading water quality and environmental resources associated withPOTW discharges Using long-term trends in dissolved oxygen as the key indicator ofwater quality improvements, this book provides a detailedretrospective analysis of the effectiveness of the water pollutioncontrol policies and regulations of the 1972 Clean Water Act. Thesuccesses of the Act that have been achieved over the past 30 yearsare placed in the historical context of the "Great SanitaryAwakening" of the 19th century and changes in public policies forwater supply and water pollution control that have evolved duringthe 20th century to protect public health and the intrinsic valueof aquatic resources. Case study sites include the ConnecticutRiver, Hudson-Raritan Estuary, Delaware Estuary, Potomac Estuary,Upper Chattahoochee River, Ohio River, Upper Mississippi River, andWillamette River. Complete with end-of-chapter summaries and conclusions, MunicipalWastewater Treatment: Evaluating Improvements in National WaterQuality is an essential book for engineers, scientists, regulators,and consultants involved in water quality management and wastewatertreatment, as well as students of environmental engineering,environmental science, and public policy.
