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:

The cogen and heating plant are closed loop systems.

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 replaced 345 toilets with low use and dual flush; we added dual flush capacity to all the rest of the toilets. All shower heads in the residential halls,gym locker rooms, and suites are low flow.
