"Water Supply and Pollution Control, Seventh Edition has been revised and modernized to meet the contemporary needs of civil and environmental engineering students who will be engaged in the design and management of water and wastewater systems, practicing engineers, and those planning to take the examination for licensing as a professional engineer. Warren Viessman, Jr. and Mark J. Hammer emphasize the application of scientific methods to problems associated with the development, movement, and treatment of water and wastewater. Treatment processes are presented in the context of what they can do rather than compartmentalizing them along clean water or wastewater lines. The concept of total water management, recognizing that all waters are potential sources of supply, is a dominant theme."--Jacket.
