According to Marie Pearthree, deputy director of Tucson Water, the utility provides retail delivery of potable and reclaimed water to more than 680,000 customers over an approximately 780-km~2 (300-mi~2) service area. The number of customers is expected to double by 2050, which is consistent with National Renewable Energy Laboratory statistics suggesting that Arizona's population will surge 34 percent between 2000 and 2020. Meeting customer demand will only become more of a challenge for Tucson Water.
