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

“60 Seconds Less” campaign encourages campus affiliates to cut 60 seconds or more off their time in the shower using community-based marketing and incentives. The campaign spread beyond the campus community and was picked up by some Bay Area news agencies.

SCU has 4 out of its 11 on-campus residence halls equipped with water meters. In the future, more installations will be made to monitor individual building water consumption and initiate an annual water challenge in which residence halls will compete against one another to see who can consume the smallest amount of water over the course of a month relative to each building’s baseline.

A class taught by Dr. Chad Raphael engaged students in exploring how to enter dialogue surrounding the drought in a proactive way using three broad approaches to water conservation – voluntary measures, creating incentives to conserve, and mandatory restrictions.

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

SCU uses recycled water to irrigate 80% of campus landscaping, and recycled water is used in toilets of the Learning Commons and Locatelli Student Activities Center. Signage throughout campus indicates that landscaping is watered with recycled water. Roughly 35% of all the water consumed by SCU is reclaimed.

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

Residence hall laundry facilities include only front-loading washing machines, using 44 percent less water than top-loading models. Low-flow shower heads are used in 95% of residence halls. These shower heads spray 2.5 gallons per minute. SCU has retrofitted faucet aerators that reduce the GPM flow from 2.2 gpm to 1.5 gpm. Low-flow/dual-flush toilets have also been installed in most campus locations.
