Explanation: The row next to each WUU holds the calculation for the WUU, which is the main water demand of the WUU.<br />

There are minus amount of source water in some WUCs. It indicates that the amount of source water is more than the demand in the WUC. It<br />

may happen when both roof-water and reclaimed water are involved as the water sources. Because the water usage is managed within WUU, the<br />

superfluous amount of water can be used by other water end-users.<br />
