Turning toilet water into tap water: Castle Rock, Colorado water treatment plant cleans waste

In Colorado, the town of Castle Rock is trying to find new ways to conserve water.

A water purification plant will soon start turning toilet water into tap water.

Every corner of Colorado is facing a future with more people and less water.

Shrinking rivers and diminishing groundwater are forcing cities and towns to make changes.

This new water purification facility in Castle Rock is designed to take surface water, including water from a nearby wastewater treatment plant, and transform it into drinking water.

Director of Utilities Mark Marlowe calls the facility's five step treatment process revolutionary.

"It's one of the most important advances in public health that the world has ever seen," Marlowe says.

Right now, Castle Rock relies mostly on non-renewable groundwater.

That supply will eventually run out.

This renewable water plant will eventually expand to meet 75% of the town's demands.

They hope to eventually be able to treat 12 million gallons a day through the plant.

While the thought of transforming treated toilet water to tap water may leave some with a bad taste in their mouth, Marlowe says high tech filters guarantee the water is clean and safe.

In fact, he says most of today's tap water is reused.

The town expects this $22 million investment, along with water conservation, will help the town save to up to $100 million over the next 20 years.

And perhaps more importantly, it'll help conserve billions of gallons of our most precious resource.

Marlowe said, "The state continues to develop and we've got to provide for the long-term future of the residents here in Castle Rock as well as around the state."
