 Clara says she's experienced triple-digit temperatures herself with no place to fill her water bottle and wants to see more fountains. They're coming, according to Michael Hammett, the city's chief innovation officer. Whatever community you're talking about should be able to find this, feel comfortable using it. He says the average temperature of the water coming out of the fountains is 75 degrees. This month, Phoenix has seen high temperatures of more than 115 degrees. The units themselves can become too hot to touch, and they've been experimenting with different coatings.
