Demands and Customer Type

As previously discussed, historical billing data are not available to differentiate
historical water use by customer type. However, some 2003 metered data are
available through a study conducted on 2003 water demands by Jehn Water
Consultants, Inc. Table 3-1 provides 2003 water demands per customer type and
Figure 3-4 shows the percentage of 2003 water demands using values from that study.

Table 3-1 Water Use by Customer in 2003
