Consumption of yellowish or brownish water
Although we do not recommend drinking brownish or yellowish-coloured water mainly because of the taste and smell that can be modified, coloured water can be used for other daily tasks.

Laundry during flushing periods
Before doing the laundry, check the color of the water. During the rinsing periods, it is suggested to do the laundry after 5 pm.

It is not recommended to use coloured water to wash white clothing during or after a network rinse, as it is likely the clothing will be stained, especially if bleach is used. Products that remove rust stains on various surfaces exist and are sold in hardware stores.

Let the water run
If a yellowish or brownish water episode occurs at a residence, the only way to remedy this situation is to let the cold water run from the tap (bath) until it becomes clear.

Abnormal situations
During the next operation, if you notice any abnormal situations, do not hesitate to contact the Public Works Department.
