From The Glenwood Springs Post-Independent (Ray K. Erku):

Debris flows that wreaked havoc through Glenwood Canyon over the summer are causing Silt’s water treatment center to work harder to remove pollutants from the Colorado River, a town official said.

Silt Town Manager Jeff Layman said the facility isn’t in any kind of crisis, but it’s simply having to treat water with higher levels of turbidity. The cloudy water also has higher levels of manganese and iron.

“The facility’s able to treat the water that’s coming in,” he said. “But there’s an increased amount of foreign debris that came off the burn scar.”

Silt is working with state and federal resources in the hopes of obtaining funding for either updates for the current plant or purchasing a new one.

Preliminary figures for these potential updates is around $13 million, Layman said. A new plant could potentially cost between $25 million and $30 million…

Roughly 21 miles west of Glenwood Canyon, Silt pulls its water supply from the Colorado River, and it relies on a micro-filtration water treatment system built about 15 years ago. New Castle pulls its water supply from Elk Creek.

With the treatment center having to filter out more debris, the city is already having to allocate extra funds to replace equipment. The past month saw the town approve a $48,000 payment to replace filters. Each filter costs about $1,000, and the treatment center is equipped with 96 filters.

“Usually the filters would last a number of years,” Layman said. “These lasted less than a year because of this problem.”

Silt Public Works Director Trey Fonner said he’s concerned the town’s water treatment system could go through filters more quickly than in the past.
