Hydrant Flushing

Spring 2016 Hydrant Flushing is Complete

Twice a year (spring and fall), the City of Fridley flushes out its water mains through the fire hydrants. The purpose of flushing the water lines is to clear the water mains of small amounts of sediment like iron or manganese that settles in water mains over time. We also verify that the hydrants are in good working order.

After flushing of the City's mains is completed, we suggest that you flush your hot water heater, which can accumulate sediment over time. Find instructions to flush your hot water heater here. By following these steps, not only will the hot water tank be cleaned out, but also the heater will run more efficiently and help conserve energy.


During flushing, deposits from water lines may create a yellowish to brownish discoloration of water in homes near flushing areas. While this water is safe for drinking, it may discolor laundry. If this discoloration last longer than two days, residents are asked to call the City's Public Works Department at (763) 572-3566. Resident may also call Public Works to get current flushing locations and updated information.
