Fire Hydrant Flushing


The Village of Prairie du Sac Water Utility has completed the Spring 2024 flushing.  Watch your monthly utility bill insert or the Village's website for the Fall 2024 flushing schedule.

The process of periodically “flushing” fire hydrants is an important preventative maintenance activity to ensure the integrity of the water system and deliver the highest quality water to our customers.  The Village does a village wide flushing of hydrants twice a year, usually in the spring and fall.

Hydrant flushing serves the following purposes:

  • Flushes sediments from mainline pipes, which enhances water quality.
  • Verifies the proper operation of fire hydrants and valves.
  • Aids in determining weaknesses in the water system.
  • Helps to identify closed valves and weak flows in the water main.
  • Verifies ample water flow for fire fighting.

Cloudy Water: As a result of hydrant flushing, residents in the immediate vicinity may experience temporary discoloration of their water. This discoloration is harmless, and generally consists of precipitates which do not affect the safety of water consumption. If you notice that your water is discolored, you can clear this issue by running all water faucets inside your home for approximately 15 minutes, or until the water clears. If water does not clear, please contact the Village at 643-4769. *Note: it is important you do not wash laundry while water is cloudyor discolored.  Please wait until water is clear before laundering.

The Village does not accept responsibility for clothing reported as soiled or damaged when washed in cloudy or discolored water.

Q: Why is my water pressure low?

A: Your water pressure may be low due to the flushing of fire hydrants, which lowers the water pressure in the area that is being tested. This issue will be rectified once flushing is completed.

Q: Why is my water discolored?

A: Water discoloration or turbid water is caused by the stirring of sedimentation in the water main when hydrants are flushed.

Q: What should I do about the discolored water?

A: Run all faucets within your home for approximately 15 minutes or until water clears.

Q: If water is discolored, is it safe for consumption?

A: Yes. The discoloration is caused by harmless mineral deposits which settle in the water main and are stirred during the flushing activity. The water is harmless due to the amount of chlorine that is flushed through the lines.

Q: Is it OK to wash laundry when water is discolored?

A: No. Please run all water inside the home for approximately 15 minutes or until water clears. You should check water clarity by capturing a sample from the washing machine in a clear glass or container. If water is cloudy or discolored, please do not wash laundry.

Q: Who should I contact if water does not clear after recommended precautions or for more information?

A: Call the Village at 643-4769.
