BOULDER, Colo. — City of Boulder water customers in Gunbarrel, Heatherwood, Hoover Hills and areas north of Arapahoe Avenue and east of Foothills Parkway may notice a slight change in the taste of their drinking water on Wednesday, the city said.

This taste change will occur when the Boulder Reservoir Water Treatment Facility temporarily changes water sources from the Boulder Feeder Canal to the Boulder Reservoir.

“Water source changes are a normal part of water treatment and distribution operations,” the city said in an announcement. “The potential taste change is due to differences in source water chemistry between Boulder Reservoir and the Boulder Feeder Canal, which delivers water from Carter Lake.”

No water service interruptions were expected.

Once the necessary maintenance operations are completed on Tuesday, Aug. 26, the water source will be switched back to the Boulder Feeder Canal.
