Overview
Mandates the Arizona Department of Water Resources Director require an entity that has been designated as having as assured water supply in an initial active management area that receives Central Arizona Project water to limit lost and unaccounted for water to less than 10 percent of the entity's total quantity of water that enters their distribution system.
History
Fifth Management Plan for Active Management Areas
The Arizona Department of Water Resources (ADWR) Director is required to develop a management plan for each initial active management area (AMA) for each of the five management periods outlined by statute. The plans must include a continuing mandatory conservation program for all persons withdrawing, distributing or receiving groundwater designed to achieve reductions in withdrawal of groundwater. The fifth management plan for each initial AMA was adopted and the conservation requirements remain in effect until the legislature determines otherwise (A.R.S. §§ 45-563, 45-568)(ADWR).
Lost and Unaccounted For Water
In fifth management plans for initial AMAs a large municipal provider is required to limit the amount of lost and unaccounted for water in their distribution system to no more than 10% of the total quantity of water that enters their distribution system, calculated either annually or on a three-year average basis.
Large municipal provider means a city, town, private water company or irrigation district that begins serving more than 250 acre-feet (af) of water for non-irrigation use per year after January 1, 2000 (ADWR).

(Sec. 1)
