17 CONCLUSION Citarum water covered 9 (nine) District administration and 3 (three) Municipalities of West Java and Jakarta Provinces. Most of the source of water initiated from West Java Province and utilized for irrigation, domestics, municipalities and industries in West Java Provincial area. Besides, its also supply water for Jakarta Special District of Capital City, means served across provincial administrative boundary. The basin is considered strategic at national level for which its managed by The Central Government. About half of the current population of the basin more than 16 million people live in urban areas. Current domestic and municipal water demands in the Citarum basin are estimated at 530 million m 3 annually. For optimal used of water and evenly distributed to all beneficiaries need a water technologies for the sustainability of Water Management that we hope we will receive from this training so we could used in Citarum water resources management.
