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:

We have begun a student-led educational program where upperclassmen present programs to students, set up by their dorm advisers. These programs target behavioral changes such as water consumption, closing windows, and recycling sorting.

We have also begun to target orientation as a time to help establish good habits, and are on the orientation program to push some of these educational programs and easy behavioral change initiatives.

During our mandatory student orientation program, as well as during our Green Certification program, we discuss water saving initiatives with the student body - shorter showers, reduced use of bottled water (using our water bottle filling stations around campus), and conservation measures around brushing teeth, etc.

---

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):

We have begun to replace conventional shower heads with low flow heads, and low flush toilets and toilets with a multiple-flush option around campus.
