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:

Being located in Southern California, the issues of water use and water-related behavior has been extremely prevalent at USD, especially in the years of the drought. The USD Changemaker Hub designates a campus and competition theme every two years. The theme for the past two years has been water. The Changemaker theme helps create programming, educational signage, academic topics and projects, and social entrepreneurship. Water programming included documentary showings and educational workshops. Signage throughout campus highlights the amount of water in food and ways that USD saves water. Professors use the Changemaker theme to create academic projects and encourage students to research and provide solutions to water issues. Finally, the Changemaker Challenge provides students with the opportunity to propose water-issue solutions and gain funding for water entrepreneurial ideas.

A student-lead club, What's Your 20?, installed a rain barrel in the campus garden to collect and reuse rainwater. This collected water is primarily used to water the garden that provides herbs and produce to one of the campus dining areas.

A student written and produced video was created to highlight savings projects: https://www.youtube.com/watch?v=BSaKs_jIjSQ

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):

USD has replaced shower heads and faucets throughout campus with low-flow retrofits to increase water-efficiency. Savings on these projects are estimated at more than 30,000,000 gallons annually.
