A brief description of the institution's water-related behavior change initiatives:
Stickers and signage are made available and found in washrooms or kitchenette areas around campus encouraging users to minimize water usage, though these are not universal. Residence eco-challenges are occasionally implemented which reward student residents for reducing their overall water consumption.

A brief description of the institution's water recovery and reuse initiatives:
Rainwater from the maintenance building roof is captured and used to manually irrigate landscaped areas.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
We have a program developed to retrofit buildings with low-flow plumbing fixtures. The first installation building was able to achieve 48% savings.

Data source(s) and notes about the submission:
Water use in 21/22 is down considerably from the baseline year because of COVID-19 and the resulting drop in campus population for a few years. We expect water usage to climb again in following years as campus population returns to normal.
