Full Description

Water storage tanks are an essential component of community water systems. Incold regions, storage is a critical element when emergency repairs are needed, orwhen water supply is seasonally limited. This paper describes the design,construction and operation of large volume storage facilities in cold regionswith an emphasis on the unique engineering and construction management challengesassociated with construction of these facilities in rural Alaska. Construction oflarge, flexible heated structures on permafrost requires specialized designs. Allcomponents must be insulated to minimize heat loss, to the surroundingenvironment. Heat must be continuously added and water circulated to preventfreezing. These add significantly to the design complexities. The high costsassociated with building in the Arctic, are a result of the remote locations,harsh climate and shipping costs. Currently capital costs for water storage tanksrange from $0.25 per liter in locations with favorable soil conditions to over$1.75 per liter in areas of ice-rich permafrost. Includes 5 references, figures.
