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

2010 is the earliest available reliable data that covers these metrics. It is also the year before significant campus growth.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	5,504	3,904
Number of employees resident on-site	16	13
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	21,781	21,689
Full-time equivalent of employees	4,709	4,063
Full-time equivalent of students enrolled exclusively in distance education	191	30
Weighted campus users	21,104.25	20,270.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	11,176.66 Gallons	10,341.96 Gallons

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

The Oregon Model of Sustainable Development found here:
https://cpfm.uoregon.edu/oregon-model-sustainable-development

Outlines the intentions to waster waste reduction:
"The University of Oregon Model for Sustainable
Development addresses the unique aspects of
campus buildings and landscapes by focusing
on what matters most: ENERGY, WATER, AND
PEOPLE. In addition, the University of Oregon
has made a commitment for capital projects to
achieve LEED Gold."

All LEED Gold buildings use water fixtures which us <80% of the standard flow. All new construction or renovation exceeding 10,000 GSF is built to LEED Gold standards. This uses infrastructure to regulate water usage and encourage conservation.

Buildings have been outfitted with Elkay stations or goose-neck spigots as water refill stations. This encourages building users to make use of municipal waster systems which are less energy intensive than water extracted & bottled for commercial retail.

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

UO Eugene is guided by the Oregon Model for Sustainable Development and looks for opportunities to introduce water recovery and reuse initiatives with every new project. Currently, the UO Eugene campus has one building with stormwater reuse system. The Rec Center has a stormwater cistern used for non-potable water uses in the building. The UO OIMB campus has a 15,000 gallon cistern to collect stormwater for reuse. UO Portland is LEED Gold certified and has a 15,000 stormwater cistern with high-efficiency appliances.

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

Campus Design Standards Section 22 00 00 – Plumbing (domestic waters; waste; sewer) (Maintenance; Common Work Results; Schedules; Insulation; Instrumentation & Control) UO goals of sustainability, life-cycle costs, maintainability, serviceability, high performance, quality equipment, and efficient campus inventory must be maintained. First costs may be impacted slightly as a result, but a better product will follow. These design standards can be found here:
https://cpfm.uoregon.edu/campus-design-standards-0

The Oregon Model for Sustainability requires that new construction pay a fee into a fund that supports retrofit projects on older buildings across campus. The goal is to be net zero energy when new buildings are added.
