CFU Flushes Hydrants to Maintain Water Quality

Hydrant flushing is one form of preventive maintenance the Water Utility uses to protect water quality. On a rotating schedule, hydrants across the city are opened and allowed to run for several minutes. Flushing maintains better water quality by removing built-up minerals in water mains.

Hydrant Flushing in Your Neighborhood

Crews will begin hydrant flushing the week of Monday, April 13 in Zone 1. Check the map below to find your zone and follow updates.

When hydrants are flushed in a neighborhood, water to area homes may be temporarily discolored and can stain laundry. This discoloration is caused by naturally occurring minerals that can settle in pipes when water flow is low. It does not impact the safety of the water. 

However, we recommend residents avoid doing laundry when hydrants are being flushed nearby. If you notice discoloration in your water, simply run cold water from a faucet for a few minutes until it clears.

If clothes are washed in discolored water, keep them wet and call CFU at 319-268-5332 to get a special cleaning agent at no charge.
