A pastor’s life and ministry have many poignant and humorous moments, yet such stories usually stay within a small circle of family and friends. This veteran pastor shares such moments of grace and gratitude that many will enjoy through reading and reflecting. Every life has a story where “threads” of connections form a wondrous mosaic in a life of unexpected surprises and joys. An archive of ministry memories is shared in this volume, which is truly summarized by the word “blessed”—blessed to share a life of unending pleasures in ministry where pastors and parishioners remember and celebrate, often with laughter the episodes of grace encounters. Humor, especially, is God-given grace.

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.

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].

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.

WATER and WASTEWATER ENGINEERING The classic guide to water and wastewater engineering returns Water and wastewater engineering is a crucial branch of civil engineering, dealing with water resources and with the challenges posed by water and wastewater. Generations of engineers have developed techniques for purifying, desalinating, and transforming water and wastewater, techniques which have only grown more critical as climate change and global population growth create new challenges and opportunities. There has never been a more urgent need for a comprehensive guide to the management of water and its various engineering subdisciplines. Water and Wastewater Engineering: Hydraulics, Hydrology and Management, 4th edition offers key fundamentals in a practical context to engineers and engineering students. Updated to address growing urbanization and industrialization, with corresponding stress on water and wastewater systems, this vital textbook has been fully revised to reflect the latest research and case studies. This volume focuses primarily with hydrology and hydraulics, along with chapters treating groundwater and surface water sources. Readers of Hydraulics, Hydrology and Management will also find: Coverage of water supply, water sources, water distribution, and more Detailed treatment of both sanitary sewer and urban stormwater drainage In-depth analysis of infrastructure issues with respect to water resources, pumping, and handling This textbook is ideal for advanced students in civil, environmental, and chemical engineering departments, as well as for early career engineers, plant managers, and urban and regional planners.

This book is a collection of selected papers presented at the International Conference on Semigroups and Applications, held at the Cochin University of Science and Technology, India, from December 9–12, 2019. This book discusses the recent developments in semigroups theory, category theory and the applications of these in various areas of research, including structure theory of semigroups, lattices, rings and partial algebras. This book presents chapters on ordering orders and quotient rings, block groups and Hall’s relations, quotients of the Booleanization of inverse semigroup, Markov chains through semigroup graph expansions, polycyclic inverse monoids and Thompson group, balanced category and bundle category. This book will be of much value to researchers working in areas of semigroup and operator theory.
