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

The baseline water consumption year was adopted based on the performance year data from the previous AASHE STARS Report.

Optional Fields

A brief description of the institution's water-related behavior change initiatives:

Being located in Southern California, the issues of water use and water-related behavior are very pertinent to USD. As part of the Eco-Resident Certification program, USD students living on campus are educated about water conservation, taught water conservation tips, and encouraged to introduce those behaviors into their daily lives.

Additionally, though it has not been quantified, a significant amount of lawn has been removed from campus and replaced with native and/or drought-tolerant plantings. This has led to a decrease in water consumed for irrigation.

A brief description of the institution's water recovery and reuse initiatives:

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Retrofits such as low-flow aerators on faucets, water efficient toilets, and low-flow shower-heads have been implemented throughout campus buildings to help realize water savings.
