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

	Performance Year	Baseline Year
Total water withdrawal	15,780,608.46 Gallons	18,926,861.88 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	15,780,608.46 Gallons	18,926,861.88 Gallons

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

	Start Date	End Date
Performance Period	June 15, 2021	June 14, 2022
Baseline Period	June 15, 2019	June 14, 2020

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:

The baseline of an approximate Fiscal Year 2020 was adopted because it was the most recent year before which repairs were completed and a number of low-flow plumbing fixtures were installed around campus.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	688	796
Number of employees resident on-site	16	16
Number of other individuals resident on-site	8	8
Total full-time equivalent student enrollment	1,126	1,277
Full-time equivalent of employees	251	275
Full-time equivalent of students enrolled exclusively in distance education	175	100
Weighted campus users	1,085.50	1,300

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	14,537.64 Gallons	14,559.12 Gallons

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

0.15

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	684,909 Gross square feet	684,909 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	23.04 Gallons per square foot	27.63 Gallons per square foot

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

16.62

Part 3. Reduction in total water withdrawal per unit of vegetated grounds

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	230.18 Acres	230.18 Acres

Total water withdrawal per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water withdrawal per unit of vegetated grounds	68,557.69 Gallons per acre	82,226.35 Gallons per acre

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

16.62

Optional Fields

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

The College has been implementing low flow plumbing devices throughout campus. The College also has worked to detect and repair leaks, which were a major source of potable water loss.

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

Catawba College has installed a 20,000 gallon geothermal runoff recovery tank, which helps to irrigate nearly 30 acres of campus' athletic fields. The College also has a 5,000 gallon rainwater recovery and storage system at the Center for the Environment Building. Unfortunately, the College does not have metering for these sites, which prevents accurate data collection on gallons recovered and reused.

Water collected from the geothermal heating system also was used to refill the 210,000-gallon swimming pool in the Abernethy Physical Education Center.

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

Low-flush toilets are installed in all residence halls and many campus bathrooms have low-flow and automatic faucets.

Data source(s) and notes about the submission:

Although the College uses runoff from its geothermal energy system for irrigation and for water for our swimming pool and also has a rainwater collection system at our Center for the Environment Building, none of these facilities currently has metering. As a result, we have not been able to calculate our non-potable water use and are understating our total water use. We realize we need to install metering and are planning to do so.
