Data source(s) and notes about the submission:
The weighted campus user data from 2005 includes online only student data. We do not have information to separate those students from the total. Several factors that have contributed to water conservation on campus. The primary one is leak detection and repair. USU hires a company every two years and they survey the water lines around campus to identify and fix leaks. Secondly, the university has eliminated cooling towers. Thirdly, USU has replaced chemical waste dilution systems with active and passive neutralization systems. Lastly, lower water use fixtures and other conservation efforts have saved water.
