A brief description of any water recovery and reuse systems employed by the institution:

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 six other campus buildings through a seperate 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 any water metering and management systems employed by the institution:

UVic is a diverse campus that strattles two different municipalities - we have 20 different water meter accounts with one (Saanich), and 5 with the other (Oak Bay). Invoices are paid based on usage recorded by each meter. Special meters are set up at the Outdoor Aquatics Research Facility where there are weather anticipating/correcting controls and time clock programmers for irrigation systems. The outdoor irrigation systems have computer controlled timers.


A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:

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 retrofittiing 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. More plumbing retrofits are planned in the coming years. Grey water from the Outdoor Aquatics Research Facility is recycled into the toilets in six buildings, with plans to connect it to more buildings in the future.


A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:

UVic has replaced outdated water-cooling condensing units for walk-in freezers and coolers in the Student Union Building, saving approximately 20,000 m3 of water each year (equivalent to 9 Olympic swimming pools!), and replaced old aspirators in the Department of Chemistry labs with portable electric vacuum pumps, saving an estimated $5,000 annually in water costs. All appliances are placed with the highest water and energy efficiency models.


A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):

UVic is integrating "naturalized areas" on campus where the grounds are not watered or otherwise maintained during the summer growning months. The reduction in irrigation in these areas results in savings of more than 8,500 cubic metres of water and $17,000 per year. Low maintenance and native species that require less watering are being incorporated around buildings and on grounds throughout the campus.


A brief description of any weather-informed irrigation technologies employed by the institution:

UVic's water irrigation systems are state-of-the-art computer controlled systems for maximum efficiency. Watering is only done in landscaped formal lawn areas where required, mostly for asthetic purposes.


A brief description of other water conservation and efficiency strategies employed by the institution:

Many other initiatives are planned for the future as per the recommendations in the CRD Water Audit conducted in 2011/12, see: https://www.uvic.ca/sustainability/assets/docs/crdwateraudit.pdf.


The website URL where information about the institution’s water conservation and efficiency initiatives is available:

UVic has been very successful in reducing overall water use on campus over the past few years even though the campus population as continued to grow. Between 2009/10 and 2012/13, water usage fell by 80,000 m3 or 11.6%, while the campus population grew by about 1,000 students and employees. These savings were the result of implementing many significant water savings initiatives including reducing irrigation of campus grounds in the summer, running the irrigation system with state-of-the-art computer controlled systems, replacing replaced outdated water-cooling condensing units for walk-in freezers and coolers in the Student Union Building (saving the equivalent to 9 Olympic swimming pools!), and replacing old aspirators in the Department of Chemistry labs with portable electric vacuum pumps. The university also replaced outdated, inefficient toilets and urinals in two large campus buidlings, and recycles grey water from the Outdoor Aquatics Research Facility into toilets and urinals in 6 buildings.
