Based on equations given under the methods section, the performance criteria of the distribution system were determined and shown in Table 4. From the values shown in the table, the sustainability indices for pressure and velocity are 0.614 and 0.132, which are acceptable and unacceptable, respectively. In this study, the overall sustainability score of the water distribution system (average of the two) is 0.373 and it indicates that the system is just moderately sustainable in terms of the variables considered.
