Optional Fields 

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.
