Low to Medium

Part 1. Reduction in potable water use per person

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

	Performance Year	Baseline Year
Total water withdrawal	131,175,450 Gallons	129,765,700 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	131,175,450 Gallons	129,765,700 Gallons

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

	Start Date	End Date
Performance Period	Jan. 1, 2019	Dec. 31, 2019
Baseline Period	Jan. 1, 2012	Dec. 31, 2012

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:

2012 is chosen as the baseline year as this was the first year after a major renovation and addition of new campus housing.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	3,300	2,514
Number of employees resident on-site	106	5
Number of other individuals resident on-site	2	5
Total full-time equivalent student enrollment	14,040	13,420
Full-time equivalent of employees	2,029	1,881
Full-time equivalent of students enrolled exclusively in distance education	2,285	33
Weighted campus users	11,191.50	12,085.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	11,720.99 Gallons	10,737.08 Gallons

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

Part 2. Reduction in potable water use per unit of floor area

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	5,744,672 Gross square feet	4,064,387 Gross square feet

Potable water use per unit of floor area:

Data source(s) and notes about the submission:

We identified a meter error in March of 2019 that was fixed in June of 2019. Unfortunately, some meters on campus had been measuring erroneously high water usage numbers for the previous three years. Therefore our water usage numbers reflected on water bills for 2016-19 are inflated and not 100% accurate. Analyzing historical spend, we computed a need to deduct 11,363,350 gallons from total water use these years and have done so in the above total.

Total building square footage is adjusted from the total campus building square footage to remove the building space at Cade Farm and the Ecology Center because these two agricultural locations are on well water and we do not have water use data.

Vegetated grounds acreage is so much less than total campus acreage because it does not include the acreage at Cade Farm and the Ecology Center (650.9 acres). These locations are on well water and therefore are not incorporated in the water use numbers.
