Grand Canyon Trust’s involvement in the North Central Arizona Water Demand Study has been instrumental in developing water conservation programs across the Coconino Plateau.
In 2002, the Trust, in partnership with Rocky Mountain Institute, produced the North Central Arizona Water Demand Study, which lays out effective water conservation technologies and policies. This report has been influential in shaping conservation policies among regional water managers. It argues that conservation effectively creates a “new water supply” and incorporates input from stakeholders on the Coconino Plateau.
The study identifies 23 efficiency and conservation measures that could be incorporated into the region’s municipal systems, including:
- Ultra-low-flush toilets and waterless urinals
- Efficient showerheads and faucets
- High-efficiency clothes washers and dishwashers
- Turf area reductions
- Low-water plants and xeriscaping
- Efficient irrigation systems
- Hot water recirculation systems
- Automated customer leak detection systems
The report also recommends developing “alternative water supply” options such as gray water reuse, water recycling, rainwater harvesting, on-site and cluster wastewater treatment / reuse, and centralized wastewater reclamation and redistribution.
