Book Synopsis Drinking Water Distribution Systems by : National Research Council
Download or read book Drinking Water Distribution Systems written by National Research Council and published by National Academies Press. This book was released on 2007-01-22 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.
Book Synopsis Water Distribution System Monitoring by : Abigail F. Cantor
Download or read book Water Distribution System Monitoring written by Abigail F. Cantor and published by CRC Press. This book was released on 2009-03-10 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: A typical water distribution system is complex and chaotic with varying piping configurations, water flows, chemical reactions, and microbiological activity. It is therefore no surprise that monitoring water quality can be a daunting task, not to mention dealing with the devastating and costly effects of: Noncompliance with the Lead and Copper Rule Pinhole leaks in water service lines and private plumbing Vulnerability to microorganisms in the water distribution system Unwanted side effects from treatment chemicals Mistakes in treatment chemicals and dosage amounts These common water quality issues can be avoided by routinely monitoring key water quality parameters in the distribution system in a controlled and standardized manner. While proactive monitoring costs money, having water quality problems is even more costly. Water Distribution System Monitoring: A Practical Approach for Evaluating Drinking Water Quality provides a practical step-by-step approach and open-source technology for proactive water quality management. It describes a method for routinely monitoring the water distribution system by: Assembling a standardized monitoring station Planning a monitoring strategy, and Interpreting and using the water quality data Deliver safe and economical drinking water to your customers. Why wait three years to find out if the water system is in compliance with the Lead and Copper Rule? Why guess which corrosion control chemical is the right one? Why guess how much disinfection is needed in the water distribution system? Optimize your chemical usage, minimize your operational expenses, and confirm that the water is safe. Laying out a path to quality control and process improvement, this book provides the tools for well-defined and measurable control of water quality.
Book Synopsis Public Water Supply Distribution Systems by : National Research Council
Download or read book Public Water Supply Distribution Systems written by National Research Council and published by National Academies Press. This book was released on 2005-04-12 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Water Science and Technology Board has released the first report of the Committee on Public Water Supply Distribution Systems: Assessing and Reducing Risks, which is studying water quality issues associated with public water supply distribution systems and their potential risks to consumers. The distribution system, which is a critical component of every drinking water utility, constitutes a significant management challenge from both an operational and public health standpoint. This first report was requested by the EPA, as the agency considers revisions to the Total Coliform Rule with potential new requirements for ensuring the integrity of the distribution system. This first report identifies trends relevant to the deterioration of drinking water quality in distribution systems and prioritizes issues of greatest concern according to high, medium, and low priority categories. Of the issues presented in nine EPA white papers that were reviewed by the committee, cross connections and backflow, new or repaired water mains, and finished water storage facilities were judged by the committee to be of the highest importance based on their associated potential health risks. In addition, the report noted that two other issues should also be accorded high priority: premise plumbing and distribution system operator training. This first report will be followed in about 18 months by a more comprehensive final report that evaluates approaches for risk characterization and identifies strategies that could be considered to reduce the risks posed by water-quality deteriorating events.

This book was released on 2001-06-19 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this century, the United States will be challenged to provide sufficient quantities of high-quality water to its growing population. Water is a limiting resource for human well-being and social development, and projections of population growth as well as changing social values suggest that demands for this resource will increase significantly. These projections have fueled concerns among the public and water resources professionals alike about the adequacy of future water supplies, the sustainability and restoration of aquatic ecosystems, and the viability of our current water resource research programs and our institutional and physical water resource infrastructures. With the goal of outlining a roadmap to guide policymakers, the Water Science and Technology Board (WSTB) held a series of discussions at several of its meetings in 1998-2000 about the future of the nation's water resources and the appropriate research needed to achieve their long-term sustainability. From those discussions, the board produced this report, the objectives of which are to: draw attention to the urgency and complexity of water resources issues facing the United States in the twenty-first century; broadly inform decision makers, researchers, and the public about these issues and challenges; identify needed knowledge and corresponding water resources research areas that should be emphasized immediately and over the long term; and describe ways in which the setting of the water research agenda, the conduct of water research, and investments devoted to such research should be improved in the next few decades. This report discusses major research questions related to the critical water issues that face the nation. It lays out an interdisciplinary research portfolio for the next 20 years and recommends agenda-setting processes that can maximize the nation's ability to prioritize and conduct water resources research.

This book was released on 2012-07-02 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is zero hour for a new US water policy! At a time when many countries are adopting new national approaches to water management, the United States still has no cohesive federal policy, and water-related authorities are dispersed across more than 30 agencies. Here, at last, is a vision for what we as a nation need to do to manage our most vital resource. In this book, leading thinkers at world-class water research institution the Pacific Institute present clear and readable analysis and recommendations for a new federal water policy to confront our national and global challenges at a critical time. What exactly is at stake? In the 21st century, pressures on water resources in the United States are growing and conflicts among water users are worsening. Communities continue to struggle to meet water quality standards and to ensure that safe drinking water is available for all. And new challenges are arising as climate change and extreme events worsen, new water quality threats materialize, and financial constraints grow. Yet the United States has not stepped up with adequate leadership to address these problems. The inability of national policymakers to safeguard our water makes the United States increasingly vulnerable to serious disruptions of something most of us take for granted: affordable, reliable, and safe water. This book provides an independent assessment of water issues and water management in the United States, addressing emerging and persistent water challenges from the perspectives of science, public policy, environmental justice, economics, and law. With fascinating case studies and first-person accounts of what helps and hinders good water management, this is a clear-eyed look at what we need for a 21st century U.S. water policy.

Book Synopsis Water Reuse by : National Research Council
Download or read book Water Reuse written by National Research Council and published by National Academies Press. This book was released on 2012-07-17 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.
Book Synopsis Regional Cooperation for Water Quality Improvement in Southwestern Pennsylvania by : National Research Council
Download or read book Regional Cooperation for Water Quality Improvement in Southwestern Pennsylvania written by National Research Council and published by National Academies Press. This book was released on 2005-04-04 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The city of Pittsburgh and surrounding area of southwestern Pennsylvania face complex water quality problems, due in large part to aging wastewater infrastructures that cannot handle sewer overflows and stormwater runoff, especially during wet weather. Other problems such as acid mine drainage are a legacy of the region's past coal mining, heavy industry, and manufacturing economy. Currently, water planning and management in southwestern Pennsylvania is highly fragmented; federal and state governments, 11 counties, hundreds of municipalities, and other entities all play roles, but with little coordination or cooperation. The report finds that a comprehensive, watershed-based approach is needed to effectively meet water quality standards throughout the region in the most cost-effective manner. The report outlines both technical and institutional alternatives to consider in the development and implementation of such an approach.
