AWWA's most popular handbook for distribution operator personnel is an indispensable reference for operators and supervisors alike on water distribution system operation and equipment. This fourth edition is based on the operator certification knowledge requirements included in the Associated Boards of Certification (ABC) Need-To-Know criteria, as well as that of several state certification boards (e.g. California, Pennsylvania, and Texas).What's new?Several new chapters cover topics that have emerged since the publication of the last edition, and others, including the regulatory overview chapter, were revised extensively. New chapters describe the management approach to distribution system operation and the operational practices operators can use to improve system performance. The disinfection of pipelines and storage facilities is now included as its own chapter.And the math calculations that distribution system operators need to know are included as concrete examples of what operators need to know.Additional coverage includes the types of water pipes, installation practices, excavation, pipe flushing and rehabilitation, storage tanks, water wells, pumps, motors, hydrants, meters, valves, corrosion prevention, leak detection, instrumentation and control, maps, records, and maintenance.In addition, the book covers basic hydraulic concepts, health issues, and maintaining water quality in the distribution system. Many cutaway illustrations, new equipment photos, metric conversions, formulas, and equations make it an ideal day-to-day reference.

Resolving customer water quality complaints is one of the most important aspects of maintaining a successful water distribution system. Complaint investigation involves not just professional water quality proficiency, but also customer relationship skills. The Water Quality Complaint Investigators Guide covers 90% of the most common complaints from consumers. This revised edition focuses on operational practices and includes two entirely new chapters that address regulatory issues and operational practices to reduce water quality complaints. You will learn: How to avoid complaints How to deal with existing problems Most common complaints and their most common fixes Concrete information on how to deal with customers How to get to the root of the problem before having to go out to the site, which saves time and money The information in this book is of value to those learning how to investigate water quality complaints to veterans who may be facing new complaint situations, as well as the people who supervise them, laboratory technicians and customer service representatives."

Specially designed for in-the-field use, this comprehensive yet compact book will pay for itself over and over in the time you save looking for chemical and mathematic formulas, chemical feed rates, US/metric conversions, pipe and equipment data, operational parameters, construction and installation information, OSHA and USEPA regulations, and much more. More than 20 tables have been updated from the 2004 edition, to reflect information in current AWWA standards and manuals in this new edition. Many example calculations were converted to a more understandable format. Information has also been added on drought, emergency disinfection, membranes, nitrification, fluoridation, external corrosion, backflow prevention, PE pipe, fire flow requirements, sizing service lines and meters, and water audits and loss control, and more. Included is a CD with the checklists which can be printed multiple times along with color photos of the related signage. (Replaces ISBN 9781583213155)

According to the Centers for Disease Control and Prevention, 32 percent of waterborne disease outbreaks are caused by pathogen intrusion in the water distribution system. Incorporating disinfection practices for water mains and storage facilities can reduce the risk of microbial contamination. This handy guidebook provides all the correct field practices for preventing microbial contamination of the water flowing in water mains, storage tanks, and other distribution system components. NOTE TO WATER UTILITIES: To ensure that mains and storage facilities are properly disinfected prior to use, AWWA advises that water utilities should insist that their pipeline contractors have and use this book. French language version available.

This handy field reference contains all the information, charts, graphs, formulas, and definitions that are needed by wastewater system operators in performing their daily duties.
This guide compiles information from wastewater operations manuals, handbooks, standards, and many other information sources. Major sections include math, conversion factors, chemistry, safety, collection, pumps and motors, flow, wastewater treatment, biosolids, discharge, disinfection, abbreviations, and acronyms.
Information is grouped based on how it would be used by the operator. Thus, all the information you need relating to pumps will be found in its own chapter and all information on biosolids in another. The guide's small size (4-1/4 in. x 7-1/4 in.) and sturdy cover means you can throw it in your truck and go Low price means every operator can have a personal copy.

Although much has been done to simplify US drinking water regulations, a confusing array of technical information still exists, and sorting it all out is problematic. This operations-oriented book explains all the regulations and how they fit together. The book provides regulatory guidance and advisories related to USEPA regulations in a single, easy-to-follow guide. It compiles information from USEPA, AWWA, and others and presents it in an understandable format. Useful to water utility managers, treatment and distribution operators, and environmental engineers.
