Optional Fields

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

Social media, and poster campaign to Reduce Your Use of Water

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

Rain Water Harvesting is mandatory under the Physical Resources Design Standards when applicable for all new builds and substantial renovations. The Rugby and Soccer Pitches have a water cistern built under the fields to collect water for irrigation.

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

Through the Green Gryphon Initiative, a $26.2 million utility conservation retrofit project, measures to reduce water use were implemented. For example, low flow shower heads, low-flow toilets and urinals etc. where installed to replace inefficient fixtures.

Data source(s) and notes about the submission:

The University of Guelph has actively been pursuing potable water use reduction initiatives. However, over the last two years, there has been a significant increase in potable water use attributed to the opening of a large athletics facility, and an undetectable water main leak.

While LEED GOLD, the new Athletics Facility is seeing an increase in the number of members from both campus and off-campus. This increase in active users, particularly from those off-campus has resulted in a significant increase in water use.

A major contributor to the increase in potable water use can also be attributed to a water main leak. There have been multiple attempts to identify the main source of the water leak, and while other leaks have been mitigated, the main issue has yet to be resolved. The University is actively attempting to resolve this issue.
