Data source(s) and notes about the submission:

Although our potable water use/weighted campus resident has decreased only slightly, our water use overall has decreased greatly, on a floor area basis, and on a vegetated grounds basis. This pattern is understandable given that, even though the number of students has decreased, there are certain water-requiring processes that must continue regardless of the total number of students on campus. Our conservation efforts in terms of landscaping options and efficient plumbing systems have definitely paid off.

Weighted campus users for this credit are the numbers for our performance year, 2018-19. They are not the same numbers as reported in PRE-5, which reflect "the most recent data available within the three years prior to the anticipated date of submission"; we used 2020-21 data for that section.
