Fort Collins Utilities to Flush the Water Distribution System, Beginning April 1

Mar 28, 2019 | Member News

Fort Collins Utilities crews will flush the water distribution system beginning Monday, April 1, 7 a.m.-5 p.m., weekdays, for approximately eight weeks (weather permitting). When flushing Downtown, crews will begin at approximately 5 a.m. in order to be out of the area as quickly as possible.

Crews will start on Mason Street and move eastward to Northern Lights Drive (just past Ziegler Road), with Willox Lane as the northern boundary and Rock Creek Drive (south of Harmony Road) as the approximate southern boundary. See map at

When flushing, fire hydrants are opened and water flows through at high speeds, cleaning the pipes, and removing the sediments that can affect the water’s taste and color. Flushing is an essential preventative maintenance strategy for the water distribution system, helps maintain water quality and keeps our water fresh.

The flushing process doesn’t typically interrupt water service, although it can happen on occasion.
A decrease in water pressure is more common.

Sometimes the sudden rush of water can stir up sediments in the pipes and cause the water to become cloudy or discolored for a short time. This water is not harmful, though it may stain laundry. If you experience cloudy or discolored water:

  • wait until the nearby flushing is complete
  • remove faucet aerators or filters
  • run the COLD water for 10-15 minutes

If you notice improvements, continue running the cold water for an additional 10-15 minutes or until it is clear. If it is not improving, turn off the water, wait 30 minutes and repeat. If it still doesn’t clear, you can call 970-221-6700 to report your concerns.

Sometimes it speeds up the process if you run the COLD water in your bathtub, which also provides a light background to help you monitor the discoloration. Another option is to run the garden hose, weather permitting, until the water clears. It’s safe to use this water on plants and landscape.
