A brief description of when and why the water use baseline was adopted:

2011 was the first year that the university reported to STARS.

Optional Fields

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:

---

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

---

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):

Over the last few years the university has replaced plumbing and steam equipment that was likely a significant source of leaks. This year, we installed low-flow shower heads in dorms and houses. This was a student-initiated and student-led project that resulted in a green revolving fund proposal, which ultimately funded the project.

Data source(s) and notes about the submission:

Performance year GSF differs from IC-2 because we do not have water consumption data for every building. For this section, we have excluded buildings for which we have no water data so that we do not misrepresent our consumption.
