Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:

Low to Medium

Part 1

Total water use (potable and non-potable combined):

	Performance Year	Baseline Year
Total water use	62,831 Cubic meters	69,812 Cubic meters

Potable water use:

	Performance Year	Baseline Year
Potable water use	62,616 Cubic meters	69,812 Cubic meters

Start and end dates of the performance year and baseline year (or three-year periods):

	Start Date	End Date
Performance Year	Jan. 1, 2017	Dec. 31, 2017
Baseline Year	Jan. 1, 2013	Dec. 31, 2013

If end date of the baseline year/period is 2004 or earlier, provide:

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

Baseline of 2013 was adopted as it was the earliest year that full water records were available.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	720	0
Number of employees resident on-site	0	0
Number of other individuals resident on-site and/or staffed hospital beds	0	0
Total full-time equivalent student enrollment	9,419	8,347

Optional Fields

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

Part of the behavioural changes on campus: tips and best practices are share via website, newsletters to staff and faculty (The Weekly Report) along with social media post, encouraging these best practices. We conduct information booths promoting sustainability practices and shifting individuals attitudes and habits.

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

Storm water collection and management Each building has been designed with a second plumbing system that collects storm water from the roofs and stores it in a 250,000-litre bioswale cistern. This water is then used for irrigation and flushing within the Business and Information Technology building, reducing the university's fresh water consumption of treated water from municipal sources. Grey water collection and management The Aquatic Toxicology Laboratory uses approximately 88,000 litres of fresh water every day. This water is supplied by ground-source wells to ensure high-quality water that is low in metals. Grey water is then directed to a 50,000-litre underground cistern, where it is reused. Grey water usage within the buildings is then directed into the storm water management system. These systems, along with state-of-the-art sensor controls and low-flow water features throughout the buildings, help the university save 32 million litres of water every year.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

Ontario Tech has state-of-the-art sensor controls and low-flow water features throughout the buildings. In 2016, the Campus Tennis Centre was converted to a multi-sport turf facility and it 2018, the institution replaced the grass on Vaso's Field into a artificial turf; this significantly reduces the water used for irrigation to water the fields.
