ABSTRACT
The population growth, the rapid rate of economic growth and regional development will have an impact on the condition of water resources. Limited water storage infrastructure is the importance cause of allocating water resources. The objective of study is to know the water balance and water storage infrastructure in Ciujung Watershed. The analysis methods was used to calculate the amount of water supply and demand, to calculate the surplus-deficit balance, Water Consumption index (IPA), Water Availability Index per Capita refers to SNI 6728.1.2015 and water storage indicator. Water supply calculation based on the mainstay discharge of 80% (Q80). Water demands calculation from the demand of households, cities and industries (RKI), irrigation, livestock, fisheries and river maintenance. Capacity of existing water conservation storage used to predict the water storage infrastructure. The results of analysis show that the water demands in Ciujung Watershed is 37,52 m3/second, while the water supply is 36,57 m3/second. This indicates there is a water deficit of 0,95 m3/second. According to calculation, Water Consumption Index is 1,03 (bad category), It resulted that Water availability index per capita is 623,05 (water scarcity indicator). On the other hand, Indicator for water storage is 31,34% (good category).
