![]() Similarly as in the baseline scenario, the equity in terms of pressure head under the modernized distribution net- work yields the value of 1.03, revealing that quite a large variability of pressure head conditions and of rPDS among hydrants would still exist. Figure 13 shows a map of hydrants performance in terms of rPD, enabling to locate the areas where lack of adequate pressure head may occur. 10 Simulated hydrants performance for the distribution network of District 7 in its pre- sent state, under the restricted- demand delivery schedule for the 10-day peak period during the 2009 irrigation season except for the very few previously identified, would be very close to zero, or even higher than zero, revealing that the ranges of fluctuation of the rPD would be small and/or that the minimum rPD values would be in most cases above the zero-line. 12 suggests that the improved network would perform pretty well, as the values of rPDS for nearly all the hydrants, Fig. far as the hydrant sensitivity is concerned, the Fig.
