Freezing and other cold weather problems are a major cause of poor performance at wastewater treatment plants in cold climates. This report, based on experience in Alaska, in the north central U.S. and on a survey of over 200 treatment systems in northern New England, presents procedures and criteria so that designers can avoid cold weather problems in future systems. It also contains detailed guidance for assisting operators in overcoming current problems and deficiencies. The information is organized and presented in terms of the major process units that are likely to be found in a typical wastewater treatment system. A number of detailed case studies of problems and solutions of specific systems in northern New England are also included.
