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