(b) Does not include groundwater withdrawn to provide an alternative water supply pursuant to section 49-282.03.

12. 16. "Safe-yield" means a groundwater management goal which attempts to achieve and thereafter maintain a long-term balance between the annual amount of groundwater withdrawn in an active management area and the annual amount of natural and artificial recharge in the active management area.

13. 17. "Small municipal provider" means a municipal provider that supplies two hundred fifty acre-feet or less of water for non-irrigation use during a calendar year. For the purposes of this paragraph, the amount of untreated water that is supplied by a large untreated water provider during a year shall not be counted in determining whether the municipal provider supplied two hundred fifty acre-feet or less of water for non-irrigation use.

14. 18. "Untreated water" means water that is not treated to improve its quality and that is supplied by a municipal provider through a distribution system other than a potable water distribution system. END_STATUTE
