From the Centennial Citizen (Peter Jones):
The facility on Jordan Road, a few miles south of Arapahoe Road, will provide up to 12 million gallons a day of potable water from Cherry Creek to about 12,000 residents and 30,000 employees in the area. [Arapahoe County Water and Wastewater Authority and Cottonwood Water and Sanitation District] say they entered into the cooperative venture to meet customers’ increasing potable water demands and to reduce reliance on nonrenewing deep-ground water supplies. “This plant is a major step in being able to supply our customers with the growing demand of water,” Authority general manager Gary Atkin said. “The new plant will also increase the quality of the water we provide.”
Unlike other reverse-osmosis plants in the state, the Joint Water Purification Plant is incorporating a process for disinfection called “advanced oxidation” that eliminates pharmaceuticals and other industrial chemicals that can show up in a water supply. “Microfiltration” will be used to clean up the portion of the water that is returned to Cherry Creek.
