This research was aimed to investigate indigenous and modern management styles and their roots of success and stability in Arsenjan county، Fars province. Case study approach and observation، interview، and archival research techniques were used for data gathering. Priority rights of Ayesheh، Bonab and Katake Qanats of Arsenjan city were compared with the application of new cooperation models. The results of the study showed that methods of the priority rights of the Arsenjan qanats were compatible with many recent new cooperation ideas and models، indeed in some respects the local methods have priorities. It is also shown that with new technologies of withdrawal of ground water e. g.، digging new deep and semi - deep wells، qanats very soon are being to be in danger of dryness، therefore، new methods of qanats management are highly proposed. Although some recommendations for better management of the qanats، monitoring، definition and consideration of the limiting zone، harvesting of aquatic organisms and protecting the qanats water from impact of environmental pollution are presented.
