A brief description of the institution's water-related behavior change initiatives:

Water conservation behaviors are encouraged through the MSU Sustainability Pledge, the Spartan Green Living Certification Program and the Green Office Certification Program. MSU has installed filtered water bottle refill stations across campus, with a map of stations available at https://www.arcgis.com/home/webmap/viewer.html?webmap=c19558c380cd42f597a34502e0ed1e32. In addition, within Culinary Services, the back-of-the-house teams are educated on methods to conserve water and efficient use of equipment such as dishwashers. Additionally, the institution installed a new water system filtration plant and storage tower that improves water quality, accessibility and efficiency of delivery, reducing bottled water consumption. https://ipf.msu.edu/water-quality-updates

N/A

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

As a part of the 10 year building recommissioning program, low water fixtures were incorporated wherever they could be given the architecture of the older buildings. MSU continues to look for opportunities to reduce high water use fixtures and processes. For example, MSU has continued installation and upgrades of bottle filling stations, investing about $100k per year. Funding is also allocated annually for restroom improvements, which include plumbing fixture upgrades. There is also an active project to review MSU’s facility water treatment program for optimization of cost, chemical usage, system performance, and water usage. An example project includes replacing all the 2.5 GPM showerheads at the Kellogg Hotel and Conference Center with new showerheads that use 1.7 GPM in 2019.
