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

A baseline of 2011 was chosen because this is the earliest we have water data for.

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

UTM has multiple initiatives in regard to water-related change initiatives. Apart from just the collection of rainwater from UTM’s underground cistern for irrigation and flushing toilets across campus, UTM has implemented a bottled water ban. Bottled water is no longer available for sale at UTM and to ensure that community members have access to drinking water, UTM has installed/upgraded a total of 20 water fountains across campus with bottle filling spouts. 50% of all campus fountains have the ability to refill water bottles, with there being at least one bottle filling station in each building.

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

UTM has many on-going projects to reduce the amount of potable water used in campus buildings to try and improve recovery, quantity, quality and reusing for rainwater. Some of these projects are the low-flow fixtures that are integrated within many of UTM’s new buildings, rainwater harvesting systems in buildings like the Instructional Building, Deerfield Hall, Health Sciences Complex, and Maanjiwe nendamowinan. This collection of rainwater is recovered and reused for irrigation and toilet flushing. Apart from this, we have green roofs that have planted vegetation to improve both stormwater management across UTM buildings such as the C Communication Culture & Technology Building (CCT), Hazel McCallion Academic Learning Centre, Recreation, Athletics and Wellness Centre (RAWC), and the Innovation Complex. There is also a reduction of water usage in the Central Utilities Plant.

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

UTM has implemented a series of water-efficient initiatives focused on replacing plumbing fixtures, fittings, appliances, equipment, and systems. The Instructional Centre had a 42 percent reduction in water usage compared to conventional buildings through the installation of low-flow fixtures. Similarly, the Health Sciences Complex has achieved a 65 percent reduction in water consumption. This reduction is attributed to the use of low-flow fixtures and the incorporation of a large underground cistern that collects rainwater. The collected rainwater serves the dual purpose of irrigation and toilet flushing within the complex.

Deerfield Hall has a low-flow plumbing fixture, which greatly reduces water use in the building as compared to a conventional building.

Maanjiwe nendamowinan is extremely water-efficient, using 88 percent less potable water than a conventional building. It alos has a rainwater reuse system, with a capacity of 20,000 gallons which is used for irrigation and toilet flushing.
