PHOENIX - The heat wave is to blame for Phoenix residents setting a record for water usage last weekend.
The city's water department says 420 million gallons of water were used Sunday. That's up from last year's record of 382 million gallons.
Water Services Department spokesman David Cerull tells radio station KJZZ that homeowners used most of the water.
He says demand generally goes up when it gets hot and that people water their yards more for fear of plants dying. He adds that residents with pools use more water because of increased evaporation.
Last Saturday's 119-degree high marked the fourth-hottest day in metro Phoenix since authorities started keeping records more than 110 years ago. Sunday's high was an only slightly less sweltering 115 degrees.
