The article presents the results of research on changes in selected water parameters during distribution in the water supply network of the city of 22 thousand inhabitants. Water parameters were controlled at 8 points in the network, distant from Water Treatment Plant from 0.4 to 3.1 km. The location of control points was selected in order to assess the water quality depending on the pipe material and at unfavourable points - at the ends of the network. It was shown that as a result of secondary water contamination an increase in turbidity, colour and total iron occurred. The distance from the Water Treatment Plant and the type of material of the network or connection, affect the quality of the water. It was confirmed that at the ends of the network the water parameters were increased and exceeded the admissible values.
