Abstrakt

In the paper the results of experimental research on the deterioration of drinking water quality after cement mortar lining were presented. The experiments were conducted in the renovated water pipeline section in Cracow. Based on the results, the expected degree of leaching of the pollutants from cement mortar to drinking water for specified lengths and diameters of renovated pipes, as well as water velocities, was estimated.
