UDF simply means guiding water in a single direction through the pipes by systematically closing valves and releasing it through fire hydrants.
Most utilities use some form of flushing in a regular maintenance schedule by opening a hydrant in the distribution system and flushing for an extended period of time to move water. The process is known as traditional flushing. Although lots of water is moved, this is not a very effective means for cleaning inside the water mains, as the water is moving from multiple directions at a slower velocity.
UDF, on the other hand, involves the systematic closing of valves and opening of hydrants to create a single direction of flow. All that water flowing in one direction results in faster velocity and more turbulent flow, which means cleaner mains.
We flush from largest mains to smallest mains and the cleanest mains to dirtier mains. This ensures dirty water is not being pushed into clean pipes, and that the pressure stays high.
UDF is effective in:
Before commissioning a new water mainline, EPCOR will be flushing water mains in the Cougar Creek, Avens / Elk Run and Kananaskis Way areas of Canmore. This process cleans the inside of the water mains and removes sediment.
Crews will work during the daytime and will try to avoid working during the dinner hour peak flushing period.
Some areas may take more time due to geographic size, pipe material, and traffic conditions. Please note that the location schedule can change without notice.
EPCOR will be cleaning the water mains using a UDF approach. UDF simply means guiding water in a single direction through the pipes by systematically closing valves and releasing it through fire hydrants.
You may experience temporarily cloudy water or low water pressure for the duration of the flush in your area. Your water won't be turned off and you'll continue to receive uninterrupted water service to your home. Your water remains safe to drink during this time.
If you experience cloudy water, we recommend that you run your cold water tap for approximately three minutes or until the water runs clear. You should notice the water starting to clear after our flushing is complete.
A drop in water pressure caused by UDF servicing can range anywhere from 15 to 60 minutes, with an average of approximately 25 minutes.
UDF servicing doesn't affect your water bill. You're only charged for water that passes through your meter and flushed water is emptied out of the distribution system well before then.
UDF involves the systematic closing of valves and opening of hydrants to create a single direction of flow. All that water flowing in one direction results in faster velocity and more turbulent flow, which means cleaner mains.
By pumping high pressured water through the pipes and releasing it through fire hydrants, we rid the mains of biological and mineral deposits and get the cleanest, clearest water to you.
Because UDF is more effective at getting the pipes clean, we're able to flush less often. And because the pressure and velocity used in UDF is so much higher than traditional flushing, we actually run the water for a shorter duration. Our flushing schedule is also designed to ensure that we never unnecessarily flush an area.
Have you ever seen water flowing from a fire hydrant but not a fire in sight? You were probably watching a Unidirectional Flushing (UDF) service.
If you're a residential customer, you can expect temporarily cloudy water or low water pressure for the duration of the flush in your area. Your water won't be turned off and you'll continue to receive uninterrupted water service to your home.
UDF crews work around the clock for about 100 days per year, from May through September. They try to avoid working during the dinner hour peak flushing period.
For more details, view the weekly flushing schedule when it's posted. Please note that the location schedule is confirmed only about a week in advance and can change without notice.
UDF crews work in the Spring and Fall. They try to avoid working during the dinner hour peak flushing period.
