1. Why does my water look discolored after hydrant flushing?

When a hydrant is opened, there will always be temporary incidences of discolored water containing fine sediment particles. There is no health hazard associated with this discolored water. It is safe to drink and continues to meet all federal and state drinking water standards. Allow a few minutes but up to 4 hours for discoloration to dissipate. If the discoloration persists for more than 24 hours, please contact our Water Treatment Plant at 931-553-2440.

2. Is the Water Department the only ones who flush fire hydrants and lines?

No, Fire Departments are required to flush hydrants when they are testing them to ensure adequate flow and pressure is available.

3. When does flushing normally occur?

The Water Department flushes throughout the year so that the water does not stagnate in less active parts of the water distribution system. Clarksville Fire and Rescue flushes all hydrants within city limits during the spring beginning in April.

4. How does hydrant flushing affect me?

Again, the largest complaint during and just after 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 taking water from the tap or running appliances that use water (dishwashers and washing machines), you can prevent discolored water from entering your household plumbing altogether.
• Avoid doing laundry while hydrant flushing is taking place. The discolored water can sometimes stain fabrics. Wait until water runs clear at the tap before using your washing machine, and wash a load of dark clothes first. If laundry appears to be stained, keep articles wet and do not dry them. 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 you encounter discolored water following hydrant flushing, run the cold water taps throughout your home (bathroom sinks and tubs, kitchen faucets, etc.) for 5 to 10 minutes or until water clears. This allows discolored water to work its way out of your household plumbing.
• If, after hydrant flushing, your water pressure or volume seems low, clean faucet screens to remove silt and mineral sediment that could be obstructing water flow.
