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

1990/91 was selected as the baseline year to conform with Kyoto Protocol reporting. UM has focused on energy efficiency since 1977 when it hired its first energy engineer and installed its first building automation system.

A performance year of 2019/20 was used to correspond with a normal operating campus with full student capacity prior to COVID-19.

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

Water fountains are being replaced with bottle refill stations to encourage the use of reusable water bottles. District waste heat recovery has eliminated considerable process water waste.


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

District heat recovery repurposes the existing campus-wide chilled water piping network during the heating season to collect, store, and re-distribute waste heat around the Fort Garry Campus. Up to 20 MMBtu/hr of waste heat is collected from areas with too much heat and re-distributed to areas that require heat.

All walk-in coolers, freezers, and water-cooled condensers located throughout the Fort Garry Campus are connected to the district heat recovery loop. The heat extracted in these condensers was previously transferred to City water and then dumped down the drain. Presently, recovered waste heat is transferred into the campus district heat recovery loop.

This recovered heat provides preheating for most of the incoming make-up air for UM laboratory facilities. Once the heat has been removed, the cool water is returned to the water-cooled equipment to begin the process again. District waste heat recovery has eliminated considerable process water waste.


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

Water-saving measures began in 1998, as part of a $13.2M Energy Performance Contract. Upgrades included the installation of low flush toilets, low flow shower heads, low flow urinals, and low flow faucets. Performance requirements continue to become more efficient. The most recent toilets installed use 1 U.S. gallon per flush, down considerably from the 7 U.S. gallons per flush in the base year.
