This book is the second volume in a revision of Fair, Geyer, and Okun’s water and wastewater engineering two volume set. It has a greater focus on drinking water supply, rather than wastewater. Consequently, it devotes more depth to discussing water reuse issues, problems related to emerging contaminants, water supply infrastructure, and water-quality standards. The book deals with different types of municipal water systems, such as collection, purification, transmission, and distribution works. It also discusses the ways in which these systems and treatments supplement one another to produce an adequate water supply, pressure, and purification standard that meets the needs of the population.
