Fire Hydrant Testing

Hattiesburg Fire Department fire hydrant flushing

Fire Hydrant Testing

The Hattiesburg Fire Department will launch its annual fire hydrant testing program starting Monday, November 18. This program ensures compliance with the Mississippi State Rating Bureau’s requirements and plays a critical role in maintaining fire readiness and public safety.

Why is Hydrant Testing Important?

Hydrant testing evaluates the pressure and flow of every fire hydrant within Hattiesburg city limits. These inspections are essential for:

  • Ensuring hydrants are in proper working order.
  • Maintaining the city’s Class 3 fire rating.
  • Enhancing the department’s ability to respond effectively to emergencies.

What to Expect During Testing

  • Temporary water disruptions: Low pressure or discolored water are normal during testing.
  • Traffic detours: Roadblocks or detours may occur as crews work on hydrants.

If you experience extended water service issues or persistent discoloration, please contact 601-545-4500.

Frequently Asked Questions

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 resolved 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 if my residence has discolored water?
A: Run faucets within your home for a few minutes or until the water becomes clear.

Q: If water is discolored, is it safe for consumption?
A: Yes. The discoloration is caused by harmless mineral deposits that settle in the water main and are stirred during the flushing activity.

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 the 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 the laundry. If your clothes become discolored due to cloudy water, do not put them in the drier. First, run a cycle of water through your machine and rewash discolored clothes.
