Data source(s) and notes about the submission:
SDSU has implemented an Energy Information System, SkySpark, that is pull in every water meter on campus. The total water use for the performance year includes potable and non-potable combined from the main campus only (not the Imperial Valley Campuses, Calexico and Brawley). Additionally, we've implemented interactive energy dashboard around campus showing the water usage by building.
