None
A brief description of any water recovery and reuse systems employed by the institution:
Grounds has an underground 1,000 gal tank that is located in the Nursery area that captures water from our irrigation system. We have a pumping station that fills our water trucks and hydro seeder for utilization back on campus. The new Physical Sciences building has a grey water system that is used for irrigating their raised patio plantings situated between Physical Sciences and Rockefeller Hall.

None
A brief description of any water metering and management systems employed by the institution:
All buildings metered and monthly bills sent.

None
A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:
Efficient shower heads installed; low flush toilets and urinals installed throughout campus;

None
A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:
---

None
A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
Green Roofs were designed utilizing xeriscape landscaping techniques. Current data has .9 acre of xeriscape on the endowed side, .5 acre on the statutory side and ~1.2 from campus life. Various varieties of Sedum populate the majority. Only key athletic fields and a couple high profile lawn areas are permitted to use irrigation.

None
A brief description of any weather-informed irrigation technologies employed by the institution:
The Grounds Dept. manages 2.5 acres of irrigated turf and 1.25 acres of irrigated planting beds/rooftop gardens. Each site has a Rain Sensor that automatically measures precipitation and prevents the irrigation system from watering in rainy conditions. The system automatically shuts off preventing over watering during a rain event.

None
A brief description of other water conservation and efficiency strategies employed by the institution:
Water utility monitors water usage and losses, auditing on an on-going basis to ensure leakage is not occurring and water is not being wasted. Cornell has a water conservation plan on file with the Department of Health.

None

Data source(s) and notes about the submission:
Cornell Water System Production-(water served to the City of Ithaca + water served to the Town of Ithaca)+ (water purchased from Bolton Point). In regards to the weighted campus user data: the number of partners/family members of staff and professional students that also live on campus and consume resources were placed in the "in-patient hospital beds" category because there is no place in STARS 2.0 to document campus residents that are not students, employees, or in-patient hospital beds. This allows for the most honest representation of Cornell's weighted campus users.
