Alert message

Starting Monday, April 26, 2021, the Environmental Service will proceed to its unidirectional flushing operation of the drinking water distribution system. This operation will start in the west side of the city and end in the east side. It will be performed from Monday to Friday, between 7 a.m. and 3:30 p.m., for an approximate period of 5 weeks.

What is unidirectional flushing?

The unidirectional flushing that is performed once a year is intended to dislodge deposits in the watermains walls as well as to ensure the quality of drinking water. To do this, we force the water in one direction and then we evacuate it through fire hydrants. At the same time, we check the quality of infrastructure, such as street valves and fire hydrants.

Because this is a large operation, there may be a temporary drop in water pressure, with or without a reddish (rust) coloration of the water in the areas affected by the flushing. Please note that this discolouration does not pose any risk to your health.

Some tips to follow:

  • Always check the colour of the water before use. If the water is coloured, leave the cold-water taps running until the water returns clear. This should take about one minute.
  • If possible, do your laundry in the evening or on the weekends during this time.

We thank you for your understanding and your collaboration during this period and we apologize for the inconvenience related to this operation that is necessary to maintain the quality of our drinking water distribution system.
