  • Sprinkling: 8 p.m. to 11 p.m.
  • Automatic sprinklers: 2 a.m. to 5 a.m.

No permits will be issued between July 1 and August 31. Only one sprinkler system may be used at a time. Two hoses are allowed for vegetated areas of 1,400 m2 or more.

Wasteful water use

Using City drinking water for the following is strictly forbidden:

  • melting snow;
  • providing a continuous supply of water to a decorative water feature unless it is equipped with a recirculating system;
  • washing driveways, parking areas or patios;
  • watering a lawn or other vegetation when it's raining or the ground is already wet;
  • watering during a watering ban;
  • letting water run or drip;
  • washing a building more than twice a year, except to remove graffiti or tags.

For excessive water usage or waste, the fine for a first offence is $250 for an individual and $500 for a business. Fines are doubled for repeat offences.

Other uses of drinking water

Washing of vehicles, walls and windows

Washing of motor vehicles is permitted at any time as long as it is done with an auto-shutoff spray gun or wand. Residential buildings with six units or less may be washed once a year, before May 31. After that date, a permit is required. For residential buildings with more than six units and commercial, industrial and institutional buildings, washing is only allowed if it is not done with City drinking water.

Alternative water supply

If your home is served by the municipal water supply system and you also have a well or pump for using underground or surface water, you must be registered with the City. You will be given signage which you must display to avoid misunderstandings.

Construction sites

Cleaning vehicles, equipment, streets or access roads with City drinking water is prohibited.

Swimming pools

When you are opening a pool at the beginning of the season, the pool water must be treated rather than drained and replaced, unless the pool is new or needs repairs. In that case, a permit must be obtained from the Permits and Inspections Division. Pool water may be topped up at any time except during authorized watering hours. Backwashing may not exceed five minutes.

Hot tubs

Hot tubs may be filled or topped up at any time, except during watering hours. No permit is needed.

Fines

Any person who contravenes the Outdoor Water Use By-Law is liable to a fine ranging from $150 to $2,000 for an individual and from $300 to $4,000 for a business, excluding court costs.

In certain situations, outdoor use of drinking water for the purposes set out in the by-law may be partially or totally prohibited.

Water conservation

Water is a precious resource that must be protected and conserved. The Québec drinking water strategy aims to reduce per-capita drinking water consumption by 20% in 2017.

Wise water use: The 4 R's

  • Reduce the quantity of water used.
  • Replace unsuitable vegetation, and replace water-wasting devices with water-saving ones.
  • Repair leaks; sometimes all it takes is a new washer.
  • Re-use rainwater: The City gives rebates on rain barrels!

By applying the 4 R's, a family can conserve tens of thousands of litres of water annually.

A few statistics

  • Canadians are among the world's biggest users of water.
  • Quebecers use 150,000 litres of water per capita per year—twice as much as Europeans.
  • Excessive residential water consumption in Vaudreuil-Dorion may result in additional operating costs of up to $750,000 a year.
  • Lawn watering may account for as much as 50% of all residential consumption of municipal drinking water.
  • Experts estimate that half of all water usage is wasteful.

Tips and Tricks

Reduce:

  • Don't drain more water than necessary from the pool for the winter. Treat the water to avoid having to drain the pool and refill it in the spring. Don't fill it higher than 15 cm from the edge to avoid losing water by splashing.
  • Sweep driveways, parking areas and patios instead of hosing them down.
  • Wash the car at the car wash when necessary.
  • Avoid watering areas that don't need it.
  • Avoid watering in broad daylight, when it's hot and windy. Water by hand.
  • Avoid watering lawns and other well-established, tolerant plants, especially during periods of drought.
  • Keep the grass long (10 cm): it will withstand drought better and keep more moisture in the ground. Leave grass clippings on the ground and shred fallen leaves on the grass to improve water retention.
  • Turning off the tap to shave or brush your teeth saves more than eight litres of water each time.
  • Fill the sink with water to wash fruit and vegetables rather than let the tap run unnecessarily.
  • Keep a pitcher of water in the refrigerator instead of running the tap until it becomes cold.

Repair:

  • Inspect garden hoses and pool connections, and repair any leaks.

Replace, add or modify:

  • Use a pool blanket to reduce evaporation.
  • For outdoor sprinklers, opt for automatic shut-off models with rain gauges or humidity sensors, or use a timer.
  • Use large-drip nozzles to limit evaporation, a drip irrigation system or perforated hoses.
  • Seed a variety of drought-resistant plants (such as clover) in with your grass, and spread a thin layer of compost annually.
  • Add compost to the soil mix for grass and other plants, and place an 8- to 10-cm layer of mulch in landscaped areas to increase water retention.
  • When buying plants, choose perennials, which need less water than annuals. Remember, the right plant in the right place: for each species, select a location where it will thrive, and try to choose native species.
  • Install a low-flow tap aerator to cut water use in half.
  • When replacing your dishwasher, remember to choose one that saves water. The new models can reduce water consumption by 25%. Wait until the dishwasher is full before turning it on.
  • Replace old toilets with new ultra low-flush models.

Re-use:

  • Use rain barrels to collect water from eavestroughs.
