Total full-time equivalent student enrollment	17,138	13,860
Full-time equivalent of employees	2,835	1,950
Full-time equivalent of students enrolled exclusively in distance education	44.30	0
Weighted campus users	16,755.10	13,435.50

Potable water use per weighted campus user:

	Performance Year	Baseline Year

Optional Fields

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

---

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

Two of our buildings were constructed with rain water capturing and retention systems. The grey water is treated and used for non-potable uses such as cooling tower makeup and toilet flushing.

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

All restrooms undergoing renovation are retrofitted with ultra low flow (0.5 gpm) with automatic shutoff valves. All new buildings are designed and constructed with the most water efficient fixtures based on the latest energy code.
