Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
High

Total water use (potable and non-potable combined):
Performance Year Baseline Year
Total water use 655,457,000 Gallons 818,738,000 Gallons

Potable water use:
Performance Year Baseline Year
Potable water use 655,457,000 Gallons 818,738,000 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year July 1, 2017 June 30, 2018
Baseline Year July 1, 2016 June 30, 2017

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

Water baseline is from fiscal year 2016-2017, this was adopted because it was the most recent year without a focus on water sustainability and had comparable number of campus users to this recent year. This was also the fiscal year before a full-time sustainability coordinator was hired in 2018.

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

Signage is posted in bathrooms, laundry rooms, residential areas and others promoting limited and smart water use.


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

Our irrigation system is set on a timer and controlled in Facilities to ensure there is not over-watering or flooding. Only lawned areas are irrigated, primarily during the dry summer months.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

There have been major renovations to the cooling towers that significantly decreased overall college water use. Retrofits are constantly being done in bathrooms to update plumbing fixtures to efficient technologies.
