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:

The Office of Sustainability gives out reusable water bottles each semester to promote reduction in plastic bottle use. They have also designed and posted stickers in the bathrooms of resident halls that encourage students to turn off the faucet while brushing their teeth. Further, the Office has installed hydration stations in indoor and outdoor areas on campus which allow students to refill their water bottles as opposed to purchasing plastic bottles. There is also a Green Pledge available on the home page of the website of the Office of Sustainability, which encourages students to go green on campus, including by reducing their water consumption. During March of 2019, the Office of Sustainability hosted its first annual Water Week. During this week, over one hundred reusable water bottles were given out to students, a World Water Day was hosted, and a film screening concerning the water bottle industry was shown. Over one hundred students signed our pledge to say no to single-use plastic water bottles for at least one month in order to help keep our local watershed free of plastics. During Earth Week, another 100+ students signed our pledge to not use straws for at least one month.

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

There are numerous self-watering planters around campus that aid in water use reduction. The new intramural facility has a storm water management system. Pervious pavement allows rainwater to flow through it and deposit into a rain garden. This will protect water quality and decrease flooding by reducing the amount of storm water runoff. There is a drainage system under the sand volleyball court and the runoff from it flows into the berms and permeable pavement. Then it is captured in rain gardens and monitored by students through the monitoring station.

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):

All water fountains are replaced with bottle refill stations that monitor water use and plastic water bottle savings. Low flow fixtures decrease the rate of water flow and subsequently the amount of water wasted per minute. They are installed in all buildings renovated in the last five years and will be in new buildings such as the LEED Certified STEM Center.
