The City of Dorval requests the cooperation of its citizens to conserve water during the summer. For that purpose, watering restrictions are in effect in the municipality, from June 1 to September 1 of each year, as follows:
- Watering is prohibited from 7 a.m. to 7 p.m. everywhere.
- Watering is, however, allowed from 7 p.m. to 7 a.m., as follows:
- Even civic numbers: Monday, Wednesday, and Friday
- Odd civic numbers: Tuesday, Thursday, and Saturday
EXCEPTIONS AND PERMITS
- Watering by hand of gardens, flowers, trees, and shrubs, using a hose fitted with a self-closing nozzle, is permitted at all times.
- Watering a newly installed lawn is permitted daily during the two consecutive weeks following its installation, with a permit obtained, free of charge, from the Urban Planning Department (60 Martin Avenue). A proof of purchase of sod or seeds must be provided to obtain a permit.
- A permit will be issued to residents along a street where new sod has been laid following municipal work.
RESTRICTIONS AND SPECIFICS
- Watering on Sunday is prohibited.
- Repeated washing of driveways, sidewalks, patios, and exterior walls of buildings is prohibited. It is, however, authorized only once a year, between January 1 and
- June 1.
- Filling of pools is prohibited between 7 a.m. and 7 p.m.
- Watering on sidewalks, curbs, and driveways with sprinklers or automatic watering systems is prohibited.
- An automatic sprinkler system must be equipped with the following devices:
- A programmable timer that allows the system to be programmed according to the days and times permitted
- An automatic humidity sensor or an automatic shut-off device that, in case of rain, will suspend watering operations when precipitation suffices or when the humidity level in the soil is sufficient
- A reduced pressure anti-backflow valve to prevent any contamination of the drinking water distribution network
- A lever or a gate valve for manual shut-off for use exclusively in case of breaks, poor functioning, or any other urgent situation, such lever or gate valve to be accessible from outside
- An automatic watering system that is incompatible with the requirements listed above may be used, but must have been either upgraded, replaced, or put out of service before January 1, 2015.
- Any private water feature or pond, whether or not it includes a fountain, a waterfall or water jets, that is initially filled from the municipal water distribution network, must be equipped with a functioning system to recirculate the water. The use of a continuous stream of drinking water to supply any such feature is prohibited. The owner or operator of such pond or water feature incompatible with the provisions mentioned above must have taken the necessary measures to upgrade its installation or abandon its use before January 1, 2015.
- Washing of cars is permitted only with the use of a garden hose equipped with a self-closing nozzle. The use of a bucket is recommended to reduce water consumption.
- Any automatic carwash that uses water from the municipal water distribution network must be equipped with a functioning recuperation, recycling, and recirculation system of the water used to wash vehicles. The owner or operator of an automatic carwash must take the necessary measures to comply with the provisions mentioned above before January 1, 2017.
Those who contravene these restrictions could receive a fine of up to $600 in a residential area and a fine of up to $2,000 in a commercial area.
The rest of the year, common sense and respect for water, a precious resource, must dictate your actions. In Dorval, like everywhere else, much water is wasted on excessive watering and evaporation. Lawns and gardens need water, but less than one would think. Generally, they need 2 to 3 centimetres of water per week in order to develop deep roots.
It is also wise to use a broom to clean the driveway or the sidewalk rather than spraying it down with water. This saves hundreds of litres of water each time.
