Outdoor water use is an important, but relatively discretionary end use in comparison to indoor water uses related to drinking, cooking, and sanitary activities. Water cutbacks are to be based on water needs, not historical water use whenever possible. Customers knowing water shortage allocations are based on historic water use may tend to overuse water during non - drought periods so as to give them a bigger allocation during a shortage. Expressed in a different way, customers implementing water conservation activities ( "demand hardened ") should not be penalized by receiving the same percentage cutback as non - conserving customers. Figure 3.3 shows that about one third of water use over all customer classes is associated with outdoor water use. 27
