Part 1. Reduction in potable water use per person

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

	Performance Year	Baseline Year
Total water withdrawal	66,918,431 Gallons	77,226,164 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	66,918,431 Gallons	77,226,164 Gallons

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

	Start Date	End Date
Performance Period	July 1, 2019	June 30, 2020
Baseline Period	July 1, 2007	June 30, 2008

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

We are using updated data provided by the Town of Middlebury who supply our water. We do not have data available to distinguish potable from non potable. Facilities estimates that in any given year about 2 to 5% of the water we use is for irrigation depending on the weather and any projects that require revegetation work. Potable water is used for human consumption and hygiene, food prep, cooling equipment, steam production, etc. A relatively small portion of the total is for direct human use.

Figures needed to determine "Weighted Campus Users":

Total full-time equivalent student enrollment	3,951	2,803
Full-time equivalent of employees	1,168	1,059
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted campus users	4,842.75	3,643.50

Potable water use per weighted campus user:

	Performance Year	Baseline Year
