Why does the Water Division conduct hydrant flushing every year?

Conventional Flushing, Unidirectional Flushing, Spot Flushing
Rockford uses a flushing program to maintain water quality. Conducted every spring, conventional flushing consists of opening hydrants in a specified neighborhood to flush out accumulated rust and sediment. While effective, this type of flushing does not increase the speed of water flow through the pipes enough to dislodge stubborn deposits.

With the use of computerized mapping, the City of Rockford has developed a unidirectional flushing program. Unidirectional flushing consists of closing specific water system valves to create one way flow and then opening hydrants in a consecutive manner. This increases the speed of the water flow in the pipes. These high velocities produce a scouring action in the pipes, removing even the most stubborn deposits.

Unidirectional flushing uses up to 40% less water than conventional flushing and allows for a better response to localized water quality complaints. Because of better sediment removal, the effects of unidirectional flushing last longer. Additionally, unidirectional flushing will test almost all of the water system valves and hydrants, identifying those in need of repair or replacement.

Spot flushing is also often used in Rockford in areas that have a low flow or a dead end in the distribution system. This type of flushing will still be utilized throughout the entire year when weather permits.

When will flushing be done in my neighborhood?
A flushing schedule will be posted in local papers and announced via the media. Signs will be posted in areas where flushing will be taking place. Flushing will normally occur between the hours of 6:00 AM and 4:00 PM. Water service should not be interrupted. If the water appears discolored it is recommended that you give it a few hours to clear up then run your cold water faucet for a few minutes to make sure the water is cleared.

 

Fire Flow Testing

       Reasons for testing:

•    Determination of how much water is available for fire protection
•    Condition of the water distribution system and means of determining needed improvements
•    Detection of closed valves in the water system
•    Familiarize the firefighters with the type of water availability in order to be better prepared for a fire

 

If you are experiencing discolored water:


If discolored water occurs, it is not a health hazard. However, during the testing procedures, iron (red water) and manganese (black water) may become stirred up within the water main, which can create staining on the porcelain and laundry. For this reason it is vital that the public be aware of the time and area that will be affected. If there are any water quality questions /concerns, please contact the Water Quailty Section at 779-348-7151.
