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

Low to Medium

Part 1. Reduction in potable water use per person

Total water withdrawal (potable and non-potable combined):

	Performance Year	Baseline Year
Total water withdrawal	178,315,100 Gallons	111,666,000 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	178,315,100 Gallons	111,666,000 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):

	Start Date	End Date
Performance Period	Sept. 1, 2020	Aug. 31, 2021
Baseline Period	Sept. 1, 2006	Aug. 31, 2007

If end date of the baseline year/period is 2004 or earlier, provide:

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

The baseline year was selected to capture data from before a campus building boom, which dramatically increased floor area, student residents, enrolled students, and staff. Many of the buildings that have been built since this time are much more water efficient than the existing buildings, and some of the more inefficient buildings have since been demolished.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	5,154	2,646
Number of employees resident on-site	0	0
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	24,954	12,089
Full-time equivalent of employees	3,450	2,008
Full-time equivalent of students enrolled exclusively in distance education	54	0
Weighted campus users	22,551	11,234.25

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	7,907.19 Gallons	9,939.78 Gallons

Percentage reduction in potable water use per weighted campus user from baseline:

20.45

Part 2. Reduction in potable water use per unit of floor area

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	6,966,790 Gross square feet	2,772,487 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	25.60 Gallons per square foot	40.28 Gallons per square foot

Percentage reduction in potable water use per unit of floor area from baseline:

36.45

Part 3. Reduction in total water withdrawal per unit of vegetated grounds

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	180 Acres	218 Acres

Total water withdrawal per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water withdrawal per unit of vegetated grounds	990,639.44 Gallons per acre	512,229.36 Gallons per acre

Percentage reduction in total water withdrawal per unit of vegetated grounds from baseline:

-93.40

Optional Fields

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

During Earth Week and Sustainability Month, the Office of Sustainability provides various interactive educational events that include education about water usage. The Office of Sustainability also publishes educational information about water usage in the Sustainability Blog, in the Sustainability Newsletter, and on the Sustainability website.

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

UT Dallas recovers water at the LEED Platinum Student Services Building and LEED Gold Bioengineering and Sciences Building. The Student Services Building captures rainwater for irrigation use and Bioengineering and Sciences Building features an innovative system that captures rainwater, reverse ossmosis reject water harvesting, and condensate capture and utilizes the water to reduce need for potable water in irrigation.

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

UT Dallas has adopted constructions standards that require efficient fixtures in all capital projects and remodels. UT Dallas has also updated irrigation controllers in order only irrigate when plant water needs require that rainfall is supplemented, and to eliminate unnecessary irrigation. In 2022, we are conducting a water conservation opportunity survey, and we will use that data to inform future institutional initiatives.
