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

Low to Medium

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

	Performance Year	Baseline Year
Total water withdrawal	239,172,695 Gallons	290,925,113.15 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	182,949,000 Gallons	245,693,000 Gallons

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

	Start Date	End Date
Performance Period	July 1, 2021	June 30, 2022
Baseline Period	July 1, 2017	June 30, 2018

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

The baseline, Fiscal Year 2018, was chosen based on the availability of past figures needed to determine "Weighted Campus Users" and the Withdrawals of Non-Potable Water.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	5,030	5,712
Number of employees resident on-site	20	20
Number of other individuals resident on-site	10	10
Total full-time equivalent student enrollment	24,758	26,229.75
Full-time equivalent of employees	7,161	5,673
Full-time equivalent of students enrolled exclusively in distance education	5,498	4,414
Weighted campus users	21,088.25	22,059.56

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	8,675.40 Gallons	11,137.71 Gallons

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

22.11

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	7,631,162 Gross square feet	6,943,261 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	23.97 Gallons per square foot	35.39 Gallons per square foot

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

32.25

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	1,102.60 Acres	841.60 Acres

Total water withdrawal per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water withdrawal per unit of vegetated grounds	216,917.01 Gallons per acre	345,680.98 Gallons per acre

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

37.25

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

We have completed the process of placing stickers near bathroom and kitchen sinks that say, "Hear a drip, give us a tip" with the "Every drop counts" logo. Other than that, we have not included water conservation in our dorm energy challenges.

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

All of the water collected in cisterns on Main and Health Sciences Campuses is used by grounds to water plants and provide irrigation where there is no fixed system in place. The only facility owned and operated by ECU that reuses water inside the building is the water capture system at the Coastal Studies Institute in Wanshese, NC on Roanoke Island. This system cycles water back through the plumbing to flush toilets.

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

Faucet aerators have been installed on the majority of sinks across campus. The two main campus cafeterias have water efficient dishwashers. Low-flow toilets and showerheads have been installed in new and recently renovated residence halls. A rigorous leak detection and repair program has been in place for several years. There are over 200 water bottle refill stations on both campuses, which have kept more than 15 million plastic bottles out of landfills.
