GHEORGHE I. LAZAR, ALBERT TITUS CONSTANTIN, MARIE ALICE GHITESCU*, SERBAN VLAD NICOARA NUMERICAL MODELLING OF A TOWN WATER DISTRIBUTION NETWORK OPTIMUM LOCATION OF QUALITY SENSORS The analysis following a numerical simulation aims to establish the water distribution system vulnerability to a contaminant release and so to estimate the optimum locations of several quality sensors to warn against the pollution effects. The TEVA-SPOT software toolkit (as specific EPANET extension) was engaged upon a study case regarding the water distribution network of Ortisoara Town in Timi’ County (4385 inhabitants). Five sets of sensors were consecutively considered for the numerical modelling, the engaged sensors being set for three values of the detection limit and of the response time. Assumed as a possible scenario, the designed sensors had to monitor the impact of injecting (at different given moments and network nodes) two types of contaminants (chemical and biological).
