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:

Office of Sustainability initiated a program to install waterproof bluetooth speakers in residence hall shower rooms and provided playlists with songs of 4 minutes or less to help students minimize shower times. (They were asked to get out after two songs.)


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

The only rain harvesting Washington and Lee conducts is collecting rainwater on top of the cooling towers and dropping it into the sump. There is no harvested water used for irrigation yet.


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):

Shower heads across campus were replaced with low flow shower heads. Low flow plumbing fixtures are now the University's standard moving forward on construction/renovation projects.
