Denver-area authorities are embarking on $760 million worth of massive water-treatment projects, to convert substandard water into drinkable new supplies.
The projects are driven by scarcity — the growing difficulty of drawing sufficient new supplies from mountain snowpack — and by rapid depletion of groundwater wells that some metro residents rely on.
Water providers say they also increasingly are detecting new contaminants, such as pharmaceutical residues from birth-control pills, cosmetics and antidepressants, that they anticipate might have to be removed.
“We’re preparing for the future. There’s still expected to be a lot of growth along Colorado’s Front Range. That’s what these plants are for,” said Steve Witter, water resources manager for the Arapahoe County Water and Wastewater Authority.
“And there may be more contaminants in the water, which we will need to treat,” Witter said.
