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:

One of the first-year residence halls, 250-bed Merrill Dorm, was retrofit in 2015 with the Evolve ShowerStart device that helps save hot water by reducing behavioral waste. Signage was provided in the dorms to explain this device and how to use it.


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

Crop irrigation on farm from on-farm pond. This usage is not tracked or reflected in any total above, but municipal water is not used for crop irrigation.


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):

Merrill Dorm was retrofit in 2015 with lower-flow faucet aerators (0.5 gpm) and shower heads (1.5 gpm). These shower heads, and the Evolve ShowerStart device described above, were retrofit in additional residence halls in 2017.
