Back-up safety valve
All homeowners must install a back-up safety valve to prevent sewer back-ups. Should a homeowner fail to do so, the City will not be responsible for damages caused to the dwelling or its content following flooding due to a sewer back-up.
When a sewer back-up occurs, the City must first determine its cause. The resident is asked to submit his claim within 15 days of the incident and to have the sewer pipe inspected to determine where the blockage of break occurred. The resident must deposit a cheque of $125. with the City to cover part of the cost of a video inspection. Should the blockage or break be located on the municipal right of way, the cheque will be returned to the resident and the repairs will be made free of charge. Should the break or blockage be located on private property, the cheque will be cashed and the homeowner will be responsible for having the repairs carried out.
Water main break - cleaning - rust
In case of a water main break, please contact Public Works immediately. If the break is located on private property, the City will close the valve leading to the municipal water distribution system to allow the owner of the property to carry out, at his own cost, the necessary repairs. Following any interruption in water distribution, property owners must flush the in-house water distribution system and ensure that all water-operated apparatus, such as washing machines, water heaters, etc. are flushed out to eliminate rust. To eliminate rust, please let the water run until it becomes clear.
Note: Should you notice that a catch basin or sewer cover is ajar, please notify Public Works immediately.
In case of flooding in a basement, please advise the Fire Department at 9-1-1 and Public Works as soon as possible in order that they may investigate the incident and damages. If applicable, a claim must be filed with the Department of Public Affairs and Registry, 60 Martin Avenue, Dorval (Quebec), H9S 3R4, within 15 days of the incident. Under no circumstances does the City pump water out of a private yard.
