Don D. Ratnayaka, Malcom J. Brandt, and K. Michael Johnson (2009). Elsevier, 3251 Riverport Lane, Maryland Heights, MO 63043, 744 pp., $92.95, hardcover, ISBN: 978-0-7506-6843-9.
 

The sixth edition of TWORT’S Water Supply is an excellent textbook for drinking water treatment courses. It also is a good reference book because of its comprehensive coverage of all aspects of drinking water treatment, including regulation, water resources, water constituents, water treatment processes, and water distribution networks. The book focuses on applications, especially engineering applications. Professionals working in such disciplines as environmental engineering may find it extremely useful.

Since the first edition was published in 1963, this book has become the encyclopedia of drinking water treatment. It is divided into 18 chapters covering various topics, such as financing and economic aspects of supply, water sources and quality, treatment processes, hydraulics and system design, distribution, pipelines, valves, and treated-water storage.

The new edition includes updated standards for drinking water and detailed descriptions of the significance of the large number of chemicals and organisms now present in source waters. It also examines new technologies, such as membrane filtration, advanced treatment methods for micropollutants, reverse osmosis, and thermal processes.

Tables, figures (including color figures), and equations are scattered throughout the textbook to help clarify the concepts and engineering applications. The book also contains useful information not usually included in water treatment books, such as a discussion of reservoirs and river intakes, pipeline design and construction, valves and meters, pumping, and electrical control and instrumentations.
