Saving drinking water

Awareness campaign on how not to waste drinking water “Mon empreinte bleue”

Despite a perception of abundance and free-cost, water services, certain fees still represent significant costs for municipalities.
As the protection of this collective wealth is everyone’s business, it is important that citizens be aware of this environmental and economic issue. Here are some numbers that speak for themselves :

Click to see message: Shower
Average flow of a shower: 9.5 liters / minute
Average duration of a shower: 7.8 minutes
Average length of a song: 5 minutes
Our calculation: (9.5 L / min) x (7.8-5) minutes x 7 days ≈ 186.2 liters / person / week

Click to see message: Tooth Brushing
Average capacity of the faucets: 8.3 liters / min
Toothbrushing time: 3 minutes, 2 times per day
Our calculation: (8.3 L / min) x 3 minutes x 2 brushings per day x 7 days = 349 liters / week

Click to see message: Toilet
Flow of a standard toilet: 13.25 liters / flush (WaterSense, 2012)
Flow rate of a low flow toilet: 4.8 liters / flush (WaterSense, 2012)
We go to the bathroom about 5 times a day (Residential End use, Water Resource Foundation (2016)
Volume of an Olympic swimming pool: 2500 m³
Our calculation: (13,25 -4,8) L / hunting x 5 hunts / day x 365 days x 8.3 M inhabitants) ≈ 127,996,375 m3 / year
127,996,375 ÷ 2,500 m³ ≈ 51,199 Olympic swimming pools

Water Saving Strategy

In response to the commitment of 49 of the National Water Policy, Quebec adopted the Drinking Water Saving Strategy. This is part of the global context of tighter policies on water, in a perspective of integrated management and sustainable development.

Quebec is one of the largest consumers of water in the world. In 2006, the drinking water production was 35% higher than the Canadian average and 62% higher than Ontario. The volume of water distributed was 795 liters per person per day, while the Canadian average was 591 and that of Ontario was 491.

By 2025, the three objectives for all of Quebec are:

  • The 20% reduction in the amount of water distributed per person compared to 2015;
  • Achieving a moderate level of leakage according to the International Water Association’s index;
  • The gradual increase in the investments required to maintain assets sustainably while gradually eliminating the maintenance deficit.

Municipalities must:

  • Produce the Annual Review of the Municipal Strategy for Drinking Water Conservation;
  • Implement progressive actions to control water losses based on the water loss indicator;
  • Implement progressive actions to save water for consumers based on the residential consumption indicator;
  • Set up progressive actions that concern the sustainable management of municipal resources and assets;
  • Present the report of the annual report to the municipal council.

If targets are not met, municipalities must:

  • Install water meters in the non-residential sector;
  • Introduce appropriate pricing after consultation with the municipal sector.
