Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Total water use (potable and non-potable combined):
| Performance Year | Baseline Year | |
| Total water use | 171,337,000 Gallons | 177,397,000 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 62,353,000 Gallons | 64,615,000 Gallons |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Year | Sept. 1, 2016 | Aug. 31, 2017 |
| Baseline Year | Sept. 1, 2015 | Aug. 31, 2016 |
A brief description of when and why the water use baseline was adopted:
The baseline was established and adopted to create a new record with the launching of the new university on September 1, 2015.
Figures needed to determine "Weighted Campus Users":
| Performance Year | Baseline Year | |
| Number of students resident on-site | 930 | 890 |
| Number of employees resident on-site | 0 | 0 |
| Number of other individuals resident on-site and/or staffed hospital beds | 0 | 0 |
| Total full-time equivalent student enrollment | 21,724 | 16,261 |
| Full-time equivalent of employees (staff + faculty) | 3,170 | 3,029 |
| Full-time equivalent of students enrolled exclusively in distance education | 3,081 | 7,432 |
| Weighted campus users | 16,592.25 | 9,116 |
Potable water use per weighted campus user:
| Performance Year | Baseline Year | |
| Potable water use per weighted campus user | 3,757.96 Gallons | 7,088.09 Gallons |
Percentage reduction in potable water use per weighted campus user from baseline:
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area | 3,973,611 Gross square feet | 2,384,411 Gross square feet |
Potable water use per unit of floor area:
| Performance Year | Baseline Year | |
| Potable water use per unit of floor area | 15.69 Gallons per square foot | 27.10 Gallons per square foot |
Percentage reduction in potable water use per unit of floor area from baseline:
Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):
Area of vegetated grounds:
| Performance Year | Baseline Year | |
| Vegetated grounds | 594.46 Acres | 142 Acres |
Total water use (potable + non-potable) per unit of vegetated grounds:
| Performance Year | Baseline Year | |
| Total water use per unit of vegetated grounds | 288,222.93 Gallons per acre | 1,249,274.65 Gallons per acre |
Percentage reduction in total water use per unit of vegetated grounds from baseline:
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:
"Only Rain Down the Drain" signage instructs UTRGV patrons to respect aquatic life by not littering.
A brief description of the institution's water recovery and reuse initiatives:
Due to water shortages in the Rio Grande Valley, it is imperative that we continue to develop and implement prudent water management solutions through Facilities Management.
The Edinburg campus, for example, uses 1.5 million gallons of water (chill water loops) to air condition its facilities year-round. In this case, the objective is to optimize the use of water treatment chemicals in order to minimize the use of make-up water necessary for building air conditioning in both open and closed loop systems.
All development plans include rain water management that is intended to reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site. Typical examples include water gardens, which also add to the aesthetics of the location, and rainwater harvesting which collects rainfall runoff from the roofs of some select buildings and directs into the underground.
Over the years, Facilities Management staff has developed an infrastructure of programmable irrigation controllers and special designated meters to manage the use of irrigation water as well as cost. The use of these devices continues to be a significant factor in the university’s ability to effectively use water to keep the campus grounds green and beautiful throughout the year. Additionally, plants native to the region are used as campus decorative foliage which requires less water and maintenance for beautification. The Brownsville campus has air handler condensate recovery systems in most of the buildings served by cooling plant on the South side.
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):
Several water fountains around campus were upgraded to with water-bottle refilling capabilities, and Water conservation has been built into the design and remodel of facilities. It is standard practice, for example, to specify bathroom fixtures such as toilets and urinals with low-flow features. Other strategies for conserving water should also be considered whenever possible; proven technologies include HVAC condensate drains and rainwater harvesting to reclaim water for new projects.
As a new University, we must be open to the possibility of incorporating unconventional sources of water such as resacas, well water, and municipal effluent water for cooling plant and landscape irrigation uses.
