Fire Hydrant Flushing

Waterworks Division Fire Hydrant Flushing Program

The City of Nampa Waterworks Division conducts routine and non-routine flushing continuously throughout the year. Flushing is performed in an effort to improve water quality and reduce “brown water” occurrences by removing built up sediments within our water lines. Those within one square mile of the flushing point may experience discolored water or pressure irregularity. Flush times occur between 8:30 A.M. to 4:30 P.M. We cannot give exact times when flushing has concluded in your area, but it is encouraged to flush your lines, if needed, after 5 P.M. to reduce any change of sediment entering your home.

A few helpful tips:

Your tap water may temporarily appear red, brown, or blackish in color. If this occurs, simply run your cold water faucets in your bathtubs at full stream for a few minutes until the water runs clear.

To avoid any unwanted sediment build-up in your hot water heater, you should always clear your lines using cold water taps like outside faucets, sinks, and tubs.

During this flushing period, you should check your clothes washers and ice makers for any sediment before using.

If your faucets seem to be clogged or running slowly, simply remove the screens and rinse out.

The water pressure inside your home may also fluctuate at times. This is only temporary and regular water pressure will resume once this flushing period is complete.

The City would like to remind customers to be sure to occasionally flush their water systems during low use times and before resuming normal business/activities. Just a few minutes of flushing cold water taps such as outside faucets, sinks, or tubs will help clear lines.
