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 include information about taking shorter showers and turning off the water when brushing teeth as part of our monthly energy challenges.
A brief description of the institution's water recovery and reuse initiatives:
Luther uses non-potable water captured from a rain barrel system to water potted plants across campus.
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):
As Luther renovates buildings, low flow faucets, urinals, and toilets are utilized. All new construction uses the most efficient devices possible.
