IRWD Multiple Dry Year Projections

The DWR Table 7-4 (A and B) show projected supplies and demands for the potable and non- potable systems in five-year increments for five consecutive dry years. Single dry year demand changes were applied for the “first year” demands (increase 5% potable, increase 10% recycled). Demands in the multiple dry year projection are adjusted +1%, +1%, -1%, and -5% for dry years two through five respectively for potable. For non-potable, demands are adjusted +5%, -1%, -2%, and -5% for dry years two though five respectively.
