WATER AGE MODELLING AS A TOOL TO IMPROVE THE QUALITY AND REDUCE THE COSTS OF WATER TREATMENT IN POLANICA-ZDROJ

The article contains part of the results of the project Protection of Natural Water Resources in Polanica-Zdroj through Intelligent Water and sewage management. The article presents the research results into the water supply network (WDN). The aim of the research was to improve the quality of water and reduce the cost of its treatment by reducing the age of the water. For this purpose, a model was built that takes into account the time in which water stays in a given section from the moment it flows out of the intake and mixes with the water already present in the network. The research was preceded by the construction of a model based on GIS geodetic data and a digital terrain model. On the basis of the simulations and analyses carried out, a solution was proposed to reduce the average age of water in the investigated WDN.
