The objective of this paper was to determine flow characteristics within water storage tanks that are unfavorable to uniform mixing and to provide the required design features or baffles to most efficiently produce uniform flow in an economical manner. This paper focuses on the use of scale models for evaluating flow circulation in three water storage tanks. Three scale hydraulic model studies were performed to evaluate flow circulation in potable water storage tanks. The first study was performed for Denver Water to investigate general aspects of flow circulation that could be applied to the designs of two new tanks. During five tests, three variables affecting mixing were evaluated: outlet configuration; water temperature; and, flow rate. A second study for the City of Fort Collins Utilities examined various baffle configurations to increase contact time at two similar 15 million gallon (MG) Reservoirs at the Water Treatment Facility. The third study for Denver Water investigated flow circulation issues related to planned modifications to Contact Basins 2 and 3 at their Marston Water Treatment Plant.
