A brief description of the institution's water-related behavior change initiatives:

Recent water use reduction activities include:
- Sensor faucets and low-flow toilets in many buildings
- Computer controlled state-of-the-art irrigation system and reduced use of irrigation in summer months
- Treated waste water systems that recycles water from the Outdoor Aquatic Facility through toilets and urinals in eight campus buildings (saving over 4.5M litres of potable water each year)
- Implementing an Integrated Stormwater Management plan on campus
- Portable electric vacuum pumps replaced old water aspirators in the chemistry labs
- Condensing were installed to run the walk-in freezers and coolers in the Student Union Building replacing the old once-through cooling units (saving the equivalent of 9 Olympic swimming pools of water each year)


A brief description of the institution's water recovery and reuse initiatives:

UVic has a grey water system in place that treats water from the Outdoor Aquatics Research Facility with ozone and chlorine that serves the heat pump condenser in one building (ECS), and also serves the toilet and urinal flushing in eight other campus buildings through a separate plumbing system. The grey water fills a tank that is pressurized and supplies the fixtures. If the grey water is not keeping up with demand, the tank is filled with city water to make up the difference.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

In 2011 UVic was subject to a comprehensive water audit by the regional district and has been implementing the report's recommendations ever since. These include retrofitting plumbing fixtures in two large buildings, in addition to the water sensing taps and low flow toilets in all of our buildings built since 2007. Grey water from the Outdoor Aquatics Research Facility is recycled into the toilets in six buildings. UVic also has an ongoing program to retrofit once through cooling units on campus with less water intensive models. Finally, UVic has recently replaced all student residence showerheads and sinks with updated low-flow fixtures.

Additional documentation to support the submission:

The increase in consumption in 2018 and 2019 was, in part, a result of a significant water leak that was not detected for several months. This has since been repaired; however, water consumption remains higher than anticipated. Reducing water consumption remains a continuing goal for UVic. As a result of unexpected and significant increases in water usage in 2018 and 2019, the university’s goal in the short-term will be to determine the cause of these increases. Committee Actions from the Sustainability Action Plan 2020-21 are:
• Develop and install a campus-wide water monitoring system in order to identify increased water usage and infrastructure failure within a short period of time.
• Repair or replace water infrastructure as required.
