Drinking Water and Used Water

An indispensable and valuable resource, water must be managed responsibly. Learn tips and tricks for reducing your daily water consumption and for recovering rainwater!

Quebecers consume an average of 364 litres of water a day. Here are a few statistics linked to this consumption.  

ActivityAverage water consumption
Flushing the toilet20 to 28 litres
Taking a bath135 to 150 litres
Taking a shower10 to 15 litres/minute
Washing clothes120 to 160 litres/minute
Preparing meals10 to 15 litres/minute
Using a dishwasher50 to 100 litres
Washing the dishes by hand25 to 40 litres

Small Actions that Make a Big Impact

Using less water also enables you to lower your energy consumption. All that’s required is to make a few changes in your daily habits and pay special attention to your faucets.

  • Turn faucets off tightly so they don’t drip.
  • Don’t let the water run while brushing your teeth, doing the dishes or washing your car.
  • Use a volume reducer (a simple brick, for example) to decrease the amount of water in the toilet tank.
  • Keep a container of water in the refrigerator instead of running the tap until it gets cold.
  • Run the dishwasher and washing machine only when full and use the minimum amount of water required.
  • Use a broom to clean the sidewalk or alley.
  • Take shorter showers: cutting a minute or two can save almost 2,500 litres of water a month.
  • Install flow restrictors on your faucets.

In predominantly industrial zones as defined in Zoning By-law 1310, the period is from 1:00 to 6:00.

Recover rain water for watering

Rather than using drinking water, purchase a recycled tank for harvesting rainwater for use in watering your lawn and flowerbeds.

Each year, the Town sells a limited quantity of rainwater tanks at a special price. Stocks for 2023 are limited. 

Complete the pdf form to request a barrel. You can send your completed form by email to or drop it off in person at Town Hall (second floor).

*Eligibility Criteria

  • Live in or own a Town property of one of the following types: single-family dwelling, duplex, triplex
  • Have gutters on your house, garage or shed
  • Install the tank on your property, either behind or alongside the building
  • Comply with all applicable Town by-laws.

Metered Water Consumption Billing

Following the By-law No. 1419, all water provided by the Town to establishments located on its territory will be measured by meters. Here is the detail of meter readings:

Serial No.: 9999999Diameter: ½ inch
Current reading: 15-06-11153,530
Previous reading: 15-06-1079,450
Total consumption:74,080
Consumption used:74,080

Water consumption: 74,080 X $2.60 /1,000 gallons = $192.61 + $20 system fee.

Taxation Period

For the residential sector (sector 1), the billing period is usually from July 1 to June 30, covering water consumption over a full one (1) year period, although section 66 of our Water Supply By-law No. 1419 allows for variations. The bill will be produced during fall in one single operation.

For the commercial and industrial sectors (sector 2), water consumption fees and system fees are billed twice a year hence covering the periods of January 1 through June 30 and July 1 to December 31.

Water Leaks

You have excess water consumption? Excess water consumption is often caused by leaks. The following tips will help you detect them.

Leak coming from the flushing system

To see if the toilet tank is leaking, drop two or three drops of food colouring into it. If the water in the bowl becomes coloured after a few moments, there’s a leak.

Leaks coming from a flushing system can be attributed to one of the following problems:

  • the valve seat sealing device, between the bowl and the tank, is defective;
  • the water is escaping through overflow;
  • the float always stays at the bottom of the tank.

Leaks coming from a faucet

These leaks are often due to wear of the faucet valve. All you have to do is replace a washer. A dripping faucet means a loss of up to 120 litres per day. A leaky flushing system can mean up to 600 litres per day.

How can you detect a leak?

Before you go to bed, read your meter. Make sure that you don’t turn on the faucet or use any water overnight. Read the meter again when you wake up. If you see a difference, it’s probably because of a leak. If there is no leak, we would invite you to evaluate your consumption habits.
