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

We are using updated data provided by the Town of Middlebury who supply our water. Our Facilities staff have provided data for the period 2011 to 2015 that they believe represent the most accurate measure of total water usage over that period of time. We do not have data available to distinguish potable from non potable. Facilities estimates that in any given year about 2 to 5% of the water we use is for irrigation depending on the weather and any projects that require revegetation work. Potable water is used for human consumption and hygiene, food prep, cooling equipment, steam production, etc. A relatively small portion of the total is for direct human use.

A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:

Low flow fixtures and appliances are used routinely for retrofits and in new construction.


A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:
---

A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
---

A brief description of any weather-informed irrigation technologies employed by the institution:

The only landscape irrigation done on campus, aside from watering to establish new plantings, is on the baseball, softball, and women’s soccer fields. This is done on an as-needed basis, and is closely monitored. All irrigation water used, with the exception of the baseball/softball fields, is drawn from a non-potable well used strictly for irrigation. irrigation computers sense rain and turn off when irrigation is not needed.
