That gives the city the green light\u00a0for another 10 years of expected housing development.<\/p>\n<p>            Rebecca Sasnett, Arizona Daily Star, File 2022<\/p>\n<p>ADWR&#8217;s decision found the city had assured supplies to serve all of its customers in the immediate Tucson environs, along with customers in the Corona de Tucson area. That&#8217;s an isolated suburban area lying far southeast of the city of Tucson along Houghton Road and north of the Santa Rita Mountains.<\/p>\n<p>The state designation cites the city&#8217;s annual supplies of 144,000 acre-feet of Central Arizona Project water, 37,000 acre-feet of groundwater and about 15,000 acre-feet of treated sewage effluent. It found those supplies will be &#8220;physically, continuously and legally available&#8221; for the next 100 years.<\/p>\n<p>Tucson Water has demonstrated that it will have &#8220;adequate delivery, storage and treatment works&#8221; in time to satisfy an annual estimated demand of 130,794.81 acre-feet per year for at least 100 years, the state decision said.<\/p>\n<p>But the possible cuts to Tucson&#8217;s CAP allotment raises questions as to how much of the supply will actually be available in the future, some outside experts have said.<\/p>\n<p>The U.S. Bureau of Reclamation has said that over time, it wants to cut at least three million acre-feet of river water use. The proposals it floated in its draft environmental impact statement on the river last winter called for cuts of possibly 77% or more of Arizona&#8217;s total CAP supplies.<\/p>\n<p>Arizona and other states in the lower Colorado River basin are proposing to cut a much smaller amount of CAP water over the next two years<\/p>\n<p>But the state officials acknowledge the cuts could grow larger in the future.<\/p>\n<p>If CAP supplies are ever cut substantially to Tucson, the new ADWR designation of an assured water supply for Tucson makes it clear that\u00a0 ADWR can &#8220;go back and look at this again&#8221; to see if it remains warranted, said Ferris. She&#8217;s a water lawyer who helped draft the 1980 state Groundwater Management Act that contains the assured water supply provision.<\/p>\n","protected":false},"excerpt":{"rendered":"The \u00a0Arizona Department of Water Resources has determined that Tucson can keep its\u00a0100-year assured water supply designation.
