3.4. Water Security Analysis
Water security is used to evaluate the performance of a hydrological system. High water security means that the system is performing well, and if the water security value is low, the system has failed to serve its intended need. Considering the monthly variation of water security, RWH systems under residential Type A, B, non-residential Type C and D have low water security values for all six scenarios. The rest of the scenario has 100% water security most of the time under any model projection for the given conditions. Residential Type B shows lesser water security levels in the first few months of the year (Figure 12).
