Abstract
Despite the fact that water pipes renovation using cement coatings has many advantages, directly after its application, the quality of the transported water may deteriorate. This is mainly due to the dissolution and leaching of some chemical elements from the protective coatings into the water. The necessity of meeting drinking water quality requirements enforces the provision of an appropriate flushing time of the freshly cemented water pipes before their return to re‐use and adjusting the length of the once‐renovated pipe. In this paper, the comparison and verification of pollutants leaching from cement mortar coatings in static and dynamic conditions are performed. Based on the experimental research performed under laboratory conditions, the curves describing the dependence of leaching pollutants from the cement mortar coating on the diameter and length of the freshly cemented water pipe are elaborated. Leaching graphs allow for forecasting some drinking water quality parameters changes soon after the water main renovation. The performed calculations for the freshly cemented transit pipeline connecting the intake of drinking water from the Dobczyce Reservoir to Cracow City have shown that the risk of exceeding the limitation values for aluminum, chromium, and lead concentration in water at the end of the renovated pipeline is very small for the type of cement commonly used in renovations – CEM I.
