Each year, the Borough of Pierrefonds-Roxboro flushes the water supply network and inspects the fire hydrants during springtime and summertime.
Unidirectional flushing of the water supply network
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 month of October.
The unidirectional flushing is intended to dislodge deposits in the water mains and preserve high water quality. Operations are carried out using predetermined flushing routes that promote better cleaning.
Fire hydrant inspection
Each hydrant is subject to a mechanical and hydraulic evaluation by our crews, twice a year (spring and fall). During the hydraulic evaluation, the hydrant is put into operation in order to measure the dynamic pressure, which increases the speed of water circulation in the pipes.
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.
