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

The baseline water consumption year is consistent with our Climate Action Plan, adopted in 2016.

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.

In 2016, a student written and produced video was created to highlight savings projects. This video remains part of the outreach campaign to reduce water consumption: https://www.youtube.com/watch?v=93GlE3IjBLg&feature=emb_logo

Finally, 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.
