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:

• Since 2007, the Office of Environmental Policy Sustainability Office has conducted an annual EcoMadness competition, in which residential dormitories on compete to reduce the most water and electricity consumption over an entire month. Individual meters on each building measure and track the water (in gallons) and energy (in kilowatt-hours) used each day. The winning buildings for each category win a free ice cream party with ice cream made from UConn cows, courtesy of the Office of Environmental Policy.
• “Stop the Drop” signs posted in residence hall restrooms give contact information for reporting leaking faucets or showerheads.


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

• UConn’s on-site Water Reclamation Facility provides non-potable water that is used by the on-site CoGeneration Plant, which converts the reclaimed water to steam in order to generate electricity and heat for the campus. The water reclamation facility allows UConn to save up to 450,000 gallons of potable water a day.
• Rainwater collection is a feature of the new Oak Building. The water is used for irrigating adjacent quads. There are two 25,000 gallons tanks that are designed to collect ground water and infiltrating rainwater from around the BMP and LID features near Oak Hall.
• An irrigation pond at the research farm has a network of channels meant to increase the amount of rainwater collected during storms, lowering the need for pumping to irrigate the research fields.


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):

• Many residential halls underwent retrofits in 2015, including the installation of low-flow showerheads and aerators on sink faucets.
• The recent LEED-Silver renovation of the Young Classroom, a 100-year old structure and the primary administrative building for the College of Agriculture, Health and Natural Resources, is one example of a whole-scale water efficiency retrofit, including faucets and toilets, in order to reduce water use and wastewater output by 30%.
