On a hot day, there’s nothing quite like a refreshing drink of water. But how would you feel if that water was sourced from the sewer? As cities across the West brace for a drier future, they’re investing in advanced water purification technology. It flushes out the contaminants in wastewater so that the murky stuff that goes down your toilet can eventually come out ready to drink at your sink. “There’s a lot of uncertainty here in terms of water resources, so we think that this is that next bucket of water that we need to tap into,” said Nazario Prieto, assistant director of Phoenix Water Services. The city of 1.6 million people is building its first advanced water purification plant that could eventually process up to 15 million gallons of wastewater a day.recy
