SUMMARY
In the first part of this paper, we deal with the sharing of water in the Ziban region. Several soties in the oasis of Chetma were carried out during the period: 2000-2020. Data and information on the water distribution network were collected from the local population and the services concerned. The results of this study show that more than 120,000 palms are irrigated by 7 springs with a total flow rate exceeding 100 l/s. A water distribution and sharing network composed of 7 Mekssem and seguias with a total length of 4 km. Directed by a council of elders, the waters are divided by the Nouba (one after another). In addition to irrigation and domestic food, spring water produces hydraulic energy to run two mills. Today, this cultural heritage is in a very advanced degraded state.
