Conservation measures in action...
City of Flagstaff
The city of Flagstaff has set up the following:
- An inverted block-rate structure (costs increase with increased water use)
- Mandatory water-use restrictions (based on supply levels), which restrict outdoor water use
- Rebate programs for low-water toilets, low-flow showerheads, efficient washers, hot water recirculators, turf removal, and rain barrels
- A xeriscape demonstration garden
- A waterless urinal retrofit project for every school in the city (estimated to save over 5 million gallons per year)
- Various water-conservation education programs
- Reclaimed water projects, including a 141 million gallon / year system at NAU
Tusayan
Tusayan (the gateway to Grand Canyon’s South Rim) has also implemented aggressive conservation measures. The community uses the runoff from the airport to supply 6 percent of their total water usage. All new development now requires double plumbing for gray water. Reclaimed water constitutes between 40 and 50 percent of Tusayan’s total usage.
New water law passed by legislature
The Arizona state legislature passed a new law in the 2007 session that authorizes cities and counties to adopt an ordinance requiring a determination of water adequacy from the Arizona Department of Water Resources before approving a subdivision. Even though this law requires a unanimous vote by the local governments, it does provide a powerful new tool to protect and manage limited water resources. It creates a way to restrict growth that relies on inadequate water supplies.
