Each year, the Borough of Pierrefonds-Roxboro flushes the water supply network and dead-en, and inspects the fire hydrants during springtime and summertime.

Unidirectional and dead-end flushing of the water supply network

Operations underway

Since mid-May, our public works crews, aqueduct section, are flushing hydrants in all sectors of the borough, one neighbourhood at a time. This operation will be carried out until the Fall period.

The unidirectional flushing is intended to dislodge deposits in the water mains and preserve high water quality. During these operations, we increase the speed of water circulation in the pipes.

Impacts to be expected

As a result, there may be a slight drop in water pressure with or without a reddish colour. This can temporarily cause some inconveniences such as stains on fabrics or dishes when using the washing machine or dishwasher.

What to do in case of cloudy water?

The operation will only last for a few hours and should not usually affect the water network. However, tap water might become brownish or rust-coloured.

  • In this case, do not use hot water, or use as little as possible, to avoid damage to the water tank.
  • Also, run the cold-water tap in the bathtub for about 30 minutes, until the water returns to its usual colour.
  • You should also run a rinse cycle in your washing machine while it is empty to avoid rust-related damage to clothing.
  • Rest assured that this is not a hazard and that the water remains safe to drink.

Flushing underway on the following streets

Our Public works crews, aqueduct section, will be flushing fire hydrants 7-days-a-week  until fall.
