WATER MAINS

All drinkable water is supplied to Dollard-des-Ormeaux by the Pierrefonds/Roxboro water filtration plant or by the Pointe-Claire filtration plant.

A permit must be obtained and administrative charges paid for every new aqueduct connection to the public sewer system. Please refer to our By-law R-2014-05 for additional questions or contact the Engineering Division at 514-684-1033.

If you need to have your water valve closed or opened when planning repairs or renovations, we ask that you call at least 48 hours before starting the work, so that an inspection of the water valve box can be done to ensure that it is working properly. For emergencies on weekends, public holidays, or after business hours, please call the Patrol at 514-684-6111.

We also recommend that you ask for an inspection of the water valve box prior to any landscaping.

Fluoride

The water supplied by the Pointe-Claire water filtration plant contains fluoride (see list of streets). The water supplied by Pierrefonds/Roxboro plant does not.

The water pressure in the City is approximately 50 to 60 pounds/in² (or PSI).

Chlorine odour

The main purpose of chlorine is to sanitize water. This element evaporates rapidly and contributes to good water quality. To remove chlorine odour, simply fill a container with water and place it in the refrigerator.

Cloudy water

Blurred water is often the result of air bubbles. You just need to let the water stand for a few minutes. It is a normal condition especially during water temperature changes (for example season changes).

Yellow, rust-coloured or dirty water

If it's only the hot water, it is probably caused by the wearing out of your water heater.

On the other hand, if it's the cold water, coloured water can be caused by the use of a fire hydrant or the reopening of a water valve after aqueduct work. Just let the cold water run until it becomes clear again.

Yearly flushing of fire hydrants

Fire hydrants are usually flushed during the summer. Please check your water after the hydrants have been flushed in your area.

Should there be rust, simply let your cold water run until it becomes clear. To avoid staining your clothes, flush the water in your washing machine before doing the laundry. A special soap is also available to remove stains. For more information please contact the City Hall front desk at 514-684-1010.

SEWERS

The City of Dollard-des-Ormeaux is serviced by two sewer systems: one for house sanitary waste and another for storm water. The sanitary waste from residential, commercial or industrial use is discharged into the (collector tunnel) underground collector of the City of Montréal.

A permit must be obtained and administrative charges paid for every new sewage connection to the public sewer system. Please refer to our By-law R-2014-095 for additional questions or contact the Engineering Division at 514-684-1033.

Sewer backflow

During a sewer backflow, the City recommends that residents contact a plumber because the blockage is most often on the private side. We suggest having a camera inspection done to get a good idea of the problem. On the other hand, if the inspection reveals that the problem is located on public property, our crews will proceed with the necessary repairs.

In that case, the resident can send a claim to the City within 15 days of the incident. A claim form is available on our Website or at the front desk of City Hall. The claim can also be sent by registered mail.

We suggest that you contact your insurance company to verify the clauses of your contact and, if need be, make a claim with them.

For emergencies on weekends, public holidays, or after business hours, please call the Patrol at 514-684-6111.

Important notices:

  1. The sewer cleanout inside your house must always be accessible and in good condition. If not, the City will not intervene.
  2. Building owners must install and maintain in good working condition one or more backwater valves or any other safety devices approved by the City to prevent any backflow (By-law 01-893, section 7.3.2).
