A brief description of when and why the water use baseline was adopted:

Eventhough the water management plan within the sustainability planning was implemented two years prior to 2002, the latter was chosen in the context of reporting requirements related to other STARS credits, namely GHG and waste management, which baselines are equivalent or similar.

Recognizing the importance of integrated water resource management, the University implemented numerous measures since 2000 to protect and enhance this resource.

Here are some examples of actions that have been taken to reduce the consumption of drinking water:
- Installation of low-flow equipment with motion detectors on the main campus;
- Continuous phase-out of equipment using water from water mains;
- Prohibition of outdoor watering, except under exceptional circumstances;
- End of the use of potable water for vacuum pumps in science research laboratories;
- Transfer of the cooling system from the cold rooms to the closed loop of cooled water;
- Installation of a water line in the tunnel to avoid the use of a problematic underground section;
- Reduction in steam consumption, which allows a reduction in the consumption of make-up water;
- Installation of low-flow showers in residences and sports centers.

The implementation of all these measures explains the large difference between the water consumption values of the baseline year and the performance year.
