	Start Date	End Date
Performance Period	Jan. 1, 2019	Dec. 31, 2019
Baseline Period	Jan. 1, 2015	Dec. 31, 2015

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:

The reference year is 2015. This decision was made due to the accessibility of the data and also because it was the year of performance in the AASHE STARS 2017 version, where UDEM received the Silver certification.
