Hydrant Flushing Begins in April

The City’s annual fire hydrant flushing program ensures the proper operation of the approximately 1,568 public fire hydrants across the City and is also vital to maintaining the distribution system in order to continue to deliver high-quality water.

System flushing is an important part of maintaining water quality and increases the water flow through the distribution system. The flushing process increases the flow rate through the line and scours the inside walls of the pipes to remove build-up of naturally occurring sediment and debris. The removal of built-up sediments improves water flow.

Annual fire hydrant inspections ensure hydrants are functioning properly. Operating the hydrant by opening and closing the values exercises the internal mechanical components and cleans the gaskets. Hydrant components such as stems, caps and plugs are lubricated. Any deficiencies are logged and repairs are completed to ensure each hydrant will perform when needed for an emergency.

What to Expect
You may experience lower than normal water pressure and a short period of water discoloration during flushing and shortly thereafter. Though the water may be discolored, it is safe to drink. However, it is advisable to avoid washing clothes, especially white fabrics, until the water runs clear. If any rust stains appear on your wet laundry, do not dry your clothes. 

Once the hydrants in your neighborhood have been flushed, you should run cold water either from your basement’s utility sink or from a hose outside. This will flush any rusty water out of your water service line. Never run warm or hot water immediately after a hydrant has been flushed, as this could lead to sediment getting into your hot water heater.
