Hydrant Flushing Project Completed

Post Date:10/08/2018

Update on October 22, 2018: This project has been completed.

*Please note:  For 2018, the flushing program will start at the north end of the Township and work its way south as the program progresses. 

Each year starting in mid-October, the Meridian Township Department of Public Works (DPW) performs hydrant flushing and winterization as routine maintenance. The DPW maintains approximately 2,200 hydrants throughout the Township. 

The process of periodically flushing fire hydrants is an important preventive maintenance activity. This allows DPW employees to test hydrants for flow and operations. Should any repairs be required it is noted and the repairs are scheduled before cold weather sets in.

Flushing, although it may appear to waste water, provides the DPW the means to clean and refresh the entire water distribution system. By discharging a large volume of water through a fire hydrant, water flow within the pipeline is increased. This increased flow actually scours the inside of the pipeline, removing and then transporting silt and mineral deposits out of the water system.

During the flushing process, it is not uncommon for a yellow, brown or reddish tint to appear in the water. Harmless mineral deposits settle in the water mains and flushing the fire hydrants stirs the deposits sometimes causing discoloration of the water.

The main impact of hydrant flushing is discolored water. Here’s what you should do if hydrant flushing is taking place in your neighborhood:

• If possible avoid using water while the hydrant flushing is taking place. By not using water from the tap (cold or hot) or running appliances that use water (dishwashers and washing machines), you can prevent discolored water from entering your household plumbing system altogether.

• If you encounter discolored water following hydrant flushing, run the cold water taps only. Do not use hot water taps throughout your home at bathroom sinks, tubs, kitchen faucets etc. for 5 to 15 minutes or until water clears. This allows discolored water to work its way out of your household plumbing system. By not using your hot water taps, this should prevent discolored water from entering your hot water system. If you do experience discolored water on your hot side, flush in the same manner as the cold system. 

• Don’t do laundry while or shortly after flushing is taking place. The discolored water can sometimes stain fabrics. Wait until water runs clear at your taps before using your washing machine, and wash a load of dark clothes first.

• If laundry appears to be stained, keep articles wet. Do Not Dry. Rewash load using a stain/rust remover (such as a product called “Rust Out”). Do Not Use Bleach on stained laundry as bleach will “set” the stain.

• If, after flushing your water pressure or volume seems low, clean faucet screens to remove silt and mineral sediment that could be obstructing water flow.

For more information, or if you experience water quality problems lasting more than four hours following hydrant flushing, please contact the Meridian Department of Public Works at 517.853.4440 or by email at
