Water and wastewater calculations manual
1 online resource (xi, 977 pages) : illustrations, figures, tables.
Water and wastewater calculations manual, third edition, provides basic principles, best practices, and detailed calculations for surface water, groundwater, drinking water treatment, and wastewater engineering. The solutions presented are based on practical field data and the most current federal and state rules and regulations. Designed for quick access to essential data, the book contains more than 100 detailed illustrations and provides both SI and U.S. customary units.

"This manual presents the basic principles and concepts relating to water/wastewater engineering and provides illustrative examples of the subject covered. To the extent possible, examples rely on practical field data and regulatory requirements have been integrated into the environmental design process. Each of the calculations provided herein is solved step-by-step in a streamlined manner that is intended to facilitate understanding."-- Preface
