Results of the maximum water ages obtained from the EPANET simulations are displayed in Table 3 for the three different scenarios with respect to mixing conditions in tanks (Mixed, FIFO, and LIFO) and for the three different types of raw water. As anticipated by Figure 2, for Mixed and FIFO modes, water age values are highest in Tank 65 and Node 160 (the nearest to Tank 65), while in LIFO mode, the values in nodes are more homogeneous and very high in the two tanks. The longest time spent by water in the WDN is predicted for the LIFO case and it corresponds to 514 and 655 h (i.e., about 3–4 weeks) for the two tanks. These values are lower for the Mixed and FIFO scenarios, but even in these cases the long permanence in Tank 65 results in water ages that are higher than 1 week (229 and 290 h for Mixed and FIFO, respectively).
