Drinking water conservation

In keeping with the Québec Government’s Strategy for water conservation, the City of Dollard-des-Ormeaux would like to raise awareness of the value of water and reduce the use of this precious resource.

Less than 1 % of the earth’s water supply can be used as drinking water. Using water efficiently and avoiding waste are fundamental to ensuring water availability in the future. Every little drop helps, so let’s all make an effort today!

Did you know that …

  • Quebecers are among the highest consumers of drinking water in the world, consuming 401 litres per day. The average Ontarian uses 267 litres every day?
  • The flushing of a toilet accounts for about 40 % of the drinking water used in a home?
  • A leak of only one drop per second wastes 9,540 litres per year which is equivalent to 80 five-minute showers?
  • The installation of low-flow aerators on kitchen and bathroom faucets saves about 5,000 litres per year, 2,500 litres of which are hot water?
  • During the summer, watering of lawns is the main source of consumption and represents 75 % of the water treated by municipalities.
  • In July, lawns are dormant. Not only should you not fertilize during this period, but you should also limit watering.
  • 85 % of landscaping problems are a result of excessive watering.
  • After a significant rainfall, your lawn does not need to be watered for a week.
  • A garden hose uses 1,000 litres per hour, the amount of water that a person drinks in three years. Your lawn does not need water every day!
  • A longer grass uses less water and looks better. Much less complicated than watering it every day!

A few tips to reduce your water usage


  • Keep a jug of water in the refrigerator instead of letting water run until it is cool enough to drink.
  • Wait until the dishwasher is full before starting a wash.
  • Close the faucet when you brush your teeth, shave or wash your face, and you will save up to 12 litres of water every minute.
  • Take a five minute shower rather than 15 minutes which will save up to 200 litres of water.
  • Check to see if your toilet tank is leaking. Add food colouring in the tank and if the coloured water shows up in the bowl, there is a leak.
  • Replace old high flow toilets with new low-flush toilets and you will save up to 11,000 litres of water each year.


  • Use a broom rather than a hose to clean your driveway.
  • Wash your car with a bucket of water rather than with a hose. You'll save up to 300 litres of water.
  • Install a rain barrel to wash your terraces, do your gardening, water your lawn and you will save up to 6,000 litres of water per year.
