**4.4 Step 2: Adopt a projection for a region**

The results displayed as the official demand projection part of the National Water Master Plan for Jordan of 2004, which has been produced by the Ministry of Water and Irrigation, in cooperation with the German Technical Cooperation (GTZ). Table 6 is a summary obtained reviewing different sections of the National Water Master Plan.

Demand is defined as the amount of water required by a user. On the other hand, consumption represents the amount actually used "at the end of pipe". Both demand and consumption do not include any kind of physical losses. However, estimating Gross demand to be supplied need to include physical losses. In Jordan and as a result of water scarcity and rationing, water demand as defined earlier, is higher than actual water consumption. This is why the official demand projection starts at a higher value than other scenarios in figure 6.

Thus, gross municipal demand figures were based on a physical loss reduction program through systematic network rehabilitation program as presented in Table 7.
