A brief description of when and why the water use baseline was adopted:

Confidence in historical records is strong beginning in 2016 for water use, following the hiring of the University's Energy Specialist who manages database of water use and the completion of water meter upgrades by local water utility.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline 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:

Non-potable water used from lake water during drought periods on the golf course and other site specific irrigation practices.

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):

Beginning in 2015, the University created the position of Energy Specialist in the Facilities Management division working on utility management issues including water consumption. Objectives of this position are data analysis and monitoring of utility consumption, measuring and verifying of energy/water conservation measures completed, and championing energy/water conservation efforts on all scales; assessing cost effectiveness, technical feasibility, impact and acceptance. Close attention to the billing of water had found irregularities that have been addressed. And a strong preventative maintenance program carried out by the Facilities Management team keeps the fixtures performing as they were designed. Most fixtures upgrades have been completed at this time.
