Environmental: The state’s golf courses and
parks provide vegetation which reduces heat.

16. Water use #3 Personal use
Every day uses: Homes, drinking water,
swimming pools, lawns

Figure 1. Water uses for the average U.S. household (total = 255 gallons per household per day).

18. How is personal water managed? READ THIS SLIDE
The Arizona Department of Water Resources manages the state’s water and is the enforcement agency for issues relating to water rights.

19. How are residents encouraged to conserve lawn water use?
Xeriscaping (native plants)
