The city will purify wastewater before distributing it as potable water
The city of Castle Rock, Colo., announced plans to use treated wastewater for drinking water. The plan will involve purifying wastewater, releasing it into the East Plum Creek, recapturing and purifying it again before distributing the treated wastewater as potable water.
According to The Denver Channel, 4.5 million gal of surface water a day in the winter is treated at the Plum Creek Reclamation Authority’s wastewater treatment plant in Castle Rock. As soon as next year, Castle Rock Water plans to use toilet, drain and sink water as potable water.
“Tap water is great water, and I would argue just as good as spring water and in many cases better than bottled water,” said Mark Marlowe, the director of Castle Rock Water.
In neighboring Aurora, Colo., the city has been using a similar water reuse system to recapture river water to provide drought insurance.
"All water starts someplace. All water ends, and it goes into a giant circle and starts over again," said Greg Baker with the city of Aurora. "I think the challenge here for most people is that they have a connection between something that is not pleasant to something that is vital for safety and health."
Castle Rock Water will host an open house Feb. 23 at the Plum Creek Water Purification Facility to share more information with the public about how water reuse is safe, sustainable and economical.
