Tucson residents have been recognized for pledging to conserve more water than other cities of similar size.

Mayor Jonathan Rothschild entered the city in a national challenge to get people to think about water use, he said.

“The idea was to get people online to commit to saving water and to commit to saving waste resources, and Tucson won," Rothschild said.

Tucson beat out Las Vegas, Omaha, Miami and Atlanta.

Tucsonans pledged to save nearly 39 million gallons of water, which could reduce water bills $1.6 million, the mayor said.

As a reward, the irrigation company Rain Bird Corp. is installing more efficient irrigation equipment at Toumey Park, near South Columbus Boulevard and East 22nd Street.
