Tucson has finished at the top of a national competition designed to motivate people to conserve water, Mayor Jonathan Rothschild announced Tuesday.

Rothschild and Tucson Water spokesman Fernando Molina praised local residents who pledged to conserve 38,829,430 gallons of water in the forthcoming year to beat out other cities in its category such as Pittsburgh, Miami and Atlanta.

The city estimates the 38 million gallons of pledged water will save $1.6 million and reduce waste in the city's landfill by about 1 million pounds.

The annual National Mayor's Challenge for Water Conservation is sponsored by the Wyland Foundation. Residents who participated in the online competition were entered into a drawing to win various prizes.
