A brief description of when and why the water use baseline was adopted:
We adopted the 2007-2008 baseline year because of the availability of reliable data in that year and the alignment with the start of MSU Climate Action Plan the following year.

Optional Fields 

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:
---

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

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):
MSU has actively been evaluating faucet and shower head flow rates. Our standard is 1.5 gpm for shower heads and .5 gpm for faucets. In the past year, we replaced approximately 300 faucets and 170 shower heads with an anticipated savings of 4.2 million gallons of water per year. In addition, this retrofit alone results in $45,000 in water and energy cost savings.
