MODELING OF WATER AGE AS AN ELEMENT SUPPORTING THE MANAGEMENT OF THE WATER SUPPLY SYSTEM


Flushing pipes and cleaning of the water supply network are the basic tasks related to the network operation. They can be made in situations requiring such type of treatments, eg. the completed repair work or failures, or as long-term plans. The decision of pipes flushing should be based on an analysis of the work of the Water Supply System (WSS). Commonly used tools supporting the water supply management is a mathematical model, which can model flows and age of water. Water age analysis allows to locate places where water is stagnant. Water age is an important parameter in determining the suitability of water for consumption, with the long water age, there is higher probability that will develop health-threatening bacteria. This paper presents the results of computer simulation and water age analysis, on the basis of which it was proposed plans for flushing the network. The network model was made and calibrated in the Epanet program.
