It can be further progressed by model users according to their situation and special requirements. After deciding the system sizes based on the water usage, the comparison can be categorised into three cases: 1. different system options of WIS with the same type of water usage, i.e. comparison within water usage scenario; 2. the same system options of WIS with different types of water usage, i.e. comparison between water usage scenarios; 3. different system options of WIS with different types of water usage, i.e. comparison in the mixed situation. In general, there are certain system alternatives that are interested mostly, so they shall be involved in any case. Such alternatives are the conventional system, the system with the lowest water demand, with the lowest costs, and with lowest energy consumption, etc. As shown in Table 15, one complete set of WIS in one water entity includes seven parts and the comparison focuses on two aspects that are costs and energy consumption. Different system options may only effect changes of some parts in WIS, which are exactly the portion that needs to be compared. The comparison thereby falls into two classes: 1. within the water entity; 2. crossing levels among water entities. So the most general comparison between system options with the specified system parts are given in Table 33 and Table 34. Besides, two classes of comparison may need to be combined. One typical example is the comparison of water reuse: direct non-potable reuse in

Following such idea, the model users can implement more comparison based on their particular needs. In the same way as the water usage, the calculated cost or energy of each part in WIS can be converted to the graphs, so that the comparison becomes more understandable. Therefore, the specific software needs to be developed in order to properly manuplated the IUWS-DSM and visualise the calculation, comparison and conclusions. The realisation method for the IUWS-DSM in Software is subsequently proposed.
