The article describes the problem of the action of soft water on the reinforced concrete structures of tanks intended for storing potable water. The basis for this assessment were the results of research of reinforced concrete tanks under operation. Three tanks with a capacity of 5, 10, and 16 thousand m3 were tested. The facilities have been operated for 2, 50 and 100 years, respectively. The main purpose of the analyzes was to determine the size of selected water parameters that determine the degree of corrosion risk in concrete. Selected cases of damage to the structures of such tanks were described, with the scope of damage and the reasons for its occurrence being provided. The materials used to make anti-corrosion insulations were also analyzed, and the causes of their frequent failures were determined.
