Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:

Low to Medium

Part 1

Total water use (potable and non-potable combined):

	Performance Year	Baseline Year
Total water use	---	21,040,076 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	24,158,156 Gallons	19,992,128 Gallons

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

	Start Date	End Date
Performance Year	June 1, 2015	May 31, 2016
Baseline Year	June 1, 2007	May 31, 2008

If end date of the baseline year/period is 2004 or earlier, provide:

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

2008 is our baseline year for GHG Emission and Waste; using 2008 as the baseline for water to keep things consistent.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	1,301	1,100
Number of employees resident on-site	14	10
Number of other individuals resident on-site and/or staffed hospital beds	0	0
Total full-time equivalent student enrollment	2,121	1,889
Full-time equivalent of employees (staff + faculty)	581	542
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted campus users	2,355.25	2,100.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	10,257.15 Gallons	9,516.66 Gallons

Percentage reduction in potable water use per weighted campus user from baseline:

Part 2

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	1,425,958 Gross square feet	1,351,585 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	16.94 Gallons per square foot	14.79 Gallons per square foot

Percentage reduction in potable water use per unit of floor area from baseline:

Part 3

Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):

Yes

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	11 Acres	11 Acres

Total water use (potable + non-potable) per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water use per unit of vegetated grounds	0 Gallons per acre	1,912,734.18 Gallons per acre

Percentage reduction in total water use per unit of vegetated grounds from baseline:

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:

Where low flow aerators were installed, there are small cards drawing attention to the fact that the aerators were installed to reduce water consumption. One resident hall and one house owned by the College have water consumption metered and is accessible to occupants.

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

We capture rainwater from a parking lot then hold it in a rain garden while it is being filtered, which eventually waters trees and other landscaping.

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):

The majority of sink faucets have been converted to use 1.5 GPM aerators. Low flow shower heads were replaced at the College's athletic facility the Leonard Center.
