A break in a pipe has caused a breach at Boulder's wastewater treatment plant, but officials said it will not impact drinking water in Boulder or Lafayette.
Officials said floodwaters destroyed a section of pipeline northeast of 61st Street and Valmont Road where it crosses Boulder Creek. The break in the pipeline -- which carries 90 percent of Boulder's untreated sewage -- caused a 300-foot breach at the treatment plant that is flowing directly into Boulder Creek.
The breach is not affecting Boulder's drinking water, since the city draws that from Baseline Reservoir. Lafayette -- which also draws its drinking water from Baseline Reservoir -- is also not affected.
But officials are warning residents to stay out of flood waters and to minimize indoor water use when possible.
Officials are working to deploy contractors to make repairs to the pipeline. The treatment plant is currently processing about 10 percent of the city's wastewater through a second pipeline serving the Gunbarrel area.
The Lefthand Water District -- which serves the Niwot and Gunbarrel area -- has issued a boil advisory for its customers. No contamination has been detected, but the Colorado Department of Public Health issued the advisory as a precaution in case of a possible breach.

That order, issued just after 2:30 p.m. Saturday, is the result of a break in a Central Weld County Water District water main. The break has caused a loss of water pressure in Frederick's drinking water distribution lines, and may also have allowed contamination to enter the system, according to an emergency alert issued by the town.No contamination has been detected as of yet, but the boil water advisory has been issued as a precaution.
