• Credit Info

Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Total water use (potable and non-potable combined):

	Performance Year	Baseline Year
Total water use	---	469,953.61 Cubic meters

Potable water use:

	Performance Year	Baseline Year
Potable water use	369,743.72 Cubic meters	469,953.61 Cubic meters

Start and end dates of the performance year and baseline year (or three-year periods):

	Start Date	End Date
Performance Year	May 1, 2016	April 30, 2017
Baseline Year	May 1, 2005	April 30, 2006

A brief description of when and why the water use baseline was adopted:
Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	3,895	3,200
Number of employees resident on-site	13	0
Number of other individuals resident on-site and/or staffed hospital beds	0	0
Total full-time equivalent student enrollment	12,504	10,000
Full-time equivalent of employees (staff + faculty)	2,756	2,500
Full-time equivalent of students enrolled exclusively in distance education	871	0
Weighted campus users	11,768.75	10,175

Potable water use per weighted campus user:

	Performance Year	Baseline Year
