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

Low to Medium

Part 1

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

	Performance Year	Baseline Year
Total water use	---	245,515,000 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	293,350,890 Gallons	236,645,000 Gallons

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

	Start Date	End Date
Performance Year	July 1, 2016	June 30, 2017
Baseline Year	July 1, 2011	June 30, 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:

FY12 was the oldest readily available data for total water use.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	7,606	7,495
Number of employees resident on-site	29	20
Number of other individuals resident on-site and/or staffed hospital beds	5	0
Total full-time equivalent student enrollment	24,654	23,859
Full-time equivalent of employees (staff + faculty)	3,823	3,239
Full-time equivalent of students enrolled exclusively in distance education	3,573	2,259
Weighted campus users	20,591.75	20,508

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	14,246.04 Gallons	11,539.16 Gallons

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

Part 2

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	8,348,057 Gross square feet	7,963,155 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	35.14 Gallons per square foot	29.72 Gallons per square foot

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

Part 3

Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	1,766 Acres	1,344 Acres

Total water use (potable + non-potable) per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water use per unit of vegetated grounds	0 Gallons per acre	182,674.85 Gallons per acre

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

Optional Fields

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

---

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

When the university golf course was renovated in 2002, a pond was constructed on the golf course for irrigation purposes. This pond is the primary source of irrigation water for all Ohio University athletic fields. A well beneath the pond is used as a back-up source of water. The university is spending $1.5 million each year on steam infrastructure improvements, including a majority spent on steam condensate return systems.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

All building renovations must conform to Ohio Plumbing Code standards, section 401.3 (Water conservation), which dictate low consumption plumbing fixtures and fittings. All building renovations above $2 million must also conform to LEED silver requirements which have a prerequisite to employ strategies that in aggregate use 20% less water than the water use baseline.
