The Tucson City Council is primed to rush through an ordinance that would impose conservation rules on large water users to protect the city’s water supply from being guzzled by data centers and the like. … The council is expected to vote during Tuesday’s regular night session on a proposal to require all new businesses using at least 7.48 million gallons a month to submit a water conservation plan to the city. The plan would show how the business would reduce its water use, water losses and waste, and improve the efficiency of its water use. The ordinance would also require new, large water users to use specified percentages of reclaimed water, often at least 30% depending on how close they are to reclaimed water delivery lines.
