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:

Used non-potable water to irrigate athletic fields. Recaptured condensate return water for irrigation of landscaping on campus. Used non-potable water to irrigate plantings across campus. Continued from drought of 2016 practice changes.


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

Grounds has an underground 1,000 gal tank that is located in the Nursery area that captures water from our irrigation system. We have a pumping station that fills our water trucks and hydro seeder for utilization back on campus. The Physical Sciences building has a grey water system that is used for irrigating their raised patio plantings situated between Physical Sciences and Rockefeller Hall.


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):

Efficient shower heads installed; low flush toilets and urinals installed throughout campus;
