Optional Fields

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

SCU students, faculty, staff, and alumni can earn a “Water” Playbook Badge for completing three sustainable actions that conserve water. Example actions include: turning off the shower faucet while shampooing/soaping up; reporting leaking/dripping sinks, running toilets, or broken sprinklers to Facilities; and using a bucket to capture shower water as it heats up to water plants or wash dishes.

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.

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
