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".


Figures needed to determine "Weighted Campus Users":
Performance Year Baseline Year
Number of students resident on-site 5,658 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 25,728.50 26,229.75
Full-time equivalent of employees 5,806 5,673
Full-time equivalent of students enrolled exclusively in distance education 4,390.50 4,414
Weighted campus users 21,787.50 22,059.56

Potable water use per weighted campus user:
Performance Year Baseline Year
Potable water use per weighted campus user 10,445.21 Gallons 11,137.71 Gallons

Percentage reduction in potable water use per weighted campus user from baseline:
6.22

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area 7,462,440 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 30.50 Gallons / GSF 35.39 Gallons / GSF

Percentage reduction in potable water use per unit of floor area from baseline:
13.82

Area of vegetated grounds:
Performance Year Baseline Year
Vegetated grounds 1,008.70 Acres 841.60 Acres

Total water withdrawal per unit of vegetated grounds:
Performance Year Baseline Year
Total water withdrawal per unit of vegetated grounds 272,731.34 Gallons / Acre 345,680.98 Gallons / Acre

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

We have continued (but not yet 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 Manteo, NC. 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 175 water bottle refill stations on both campuses, which have kept more than 10 million plastic bottles out of landfills.

Part 3 Notes:

FY 19 Total Campus Area = 1,580 acres

FY 19 Building Footprint Area = 171.3 acres

FY 16 Non-Permeable Area = 400 acres

Vegetated Area = 1,580 - 171.3 - 400 = 1008.7 acres

FY 18 Total Campus Area = 1401 acres

FY 18 Building Footprint Area = 159.4 acres

FY 16 Non-Permeable Area = 400 acres

Vegetated Area = 1401 - 159.4 - 400 = 841.6 acres
