Abstract: Poor mixing conditions have been identified as one of the main reasons for ice formation in water towers located in cold climates. Also, poor mixing conditions have been identified as one of the main reasons for thermal stratification in water towers during summer. Objectives are: 1. to determine the impact of a mixer on the heat balance of a water tower and its effectiveness at preventing or reducing ice formation during winter. 2. to determine the impact of a mixing on the quality of water in the tower during summer, and 3. to determine proper operational procedures for water towers with mixers. Water distribution managers can gain information from this study to develop proper operational techniques for water towers with mixers.
