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

The water use baseline was adopted in 2014 when the Ministry of Education required all postsecondary institutions to establish a water use baseline.

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

Initially, water meters were installed according to municipal regulatory requirements regarding Industrial, Commercial and Institutional establishments (ICI). Approximately 100 water meters have been installed since March 2016.


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

The university has two projects for implementing rain water harvesting in greenhouses.


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

The university installed low-flow toilets and showerheads, as well as automatic faucets in many of the bathrooms on the downtown campus. Low-flow showerheads were also installed in the residences, which has decreased water usage by an estimated 58,000L per day. Prior to new construction or major renovation projects, project teams must perform a preliminary water budget analysis before the completion of schematic design that explores how to reduce potable water loads. They must also assess and estimate the project’s potential non-potable water supply sources and water demand volumes, including the following: indoor water demand; outdoor water demand; process, services, and equipment water demand, as applicable; and alternative supply sources for non-potable water.

The univeristy has worked towards converting or removing single-pass water cooled equipment across the campus. From these projects, water consumption has been reduced by an estimated 302,700 cubic meters per year.
