Water Use Efficiency
Many steps have been taken on campus to conserve water, and are often accomplished by simple changes in maintenance practices, equipment, or design choices. Several examples of this are highlighted below.
Landscape irrigation:
Historic flood irrigation berms remain in lawns, although irrigation has been replaced with more efficient spray heads.
- Most landscape irrigation has been converted to reclaimed water.
- Most campus irrigation has been converted to an automated system (CALSENSE) which has links to weather data. This system allows more control over the timing and quantity of watering, and saves significant labor costs associated with hand watering.
- Flood irrigation of turf in the historic parts of campus has been replaced with spray irrigation.

Vegetation:
Desert vegetation compliments the recently installed Founder's Plaza on the East side of Old Main.
- Areas of underused, marginal quality, or purely ornamental turf have been replaced with desert landscape.
- Use of drought tolerant vegetation has become a standard practice for new campus landscapes. However, as a formally designated Arboretum, the campus holds a diverse collection of plants, including some higher water use species.
Water efficient devices:
- The University has implemented waterless urinals in many campus buildings. In one building alone, 13 urinals save an estimated 500,000 gallons of water per year.

- A water feature installed in the Speedway underpass at Warren Avenue draws on rainwater collected in a cistern that is fed from water collecting in the underpass.
