A brief description of the institution's water-related behavior change initiatives:
The Office of Sustainability conducts awareness and engagement events throughout the year. Most recently, in partnership with Institute on the Environment, UMN Water Compliance department, and River Life, we hosted the We Are Water travelling exhibit and a fan engagement table at a Gopher football in the TCF Bank Stadium to inform and call to action the U community to reduce pollution by being aware that everything flows to our river and that that's where our drinking water comes from.
A brief description of the institution's water recovery and reuse initiatives:
We have a storm water catch system on top of 17th ave res hall and on the land care building. Multiple building across campus use grey water in toilet systems.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
State of Minnesota Sustainable Building Guidelines (http://www.b3mn.org/guidelines/index.html) specify low flow fixtures.
