The raw water balance of DKI Jakarta consists of the needs and availability of raw water in DKI Jakarta. The population growth and land-use changes through the year 2030 led the demand for water to increase every year. The aims of this research are to identify and to evaluate the population of land-use changes that affect raw water needs in DKI Jakarta. Data analysis was carried out by processing and calculating from data that had been obtained based on the reference year (2010). Population growth and land conversion in 2010, it will form a change in land-use in 2030 affected to raw water balance in DKI Jakarta. Cisadane and Citarum Rivers, rain harvest and reverse osmosis becomes an alternative water resource to increase the availability of raw water. The amount of raw water deficit after the application of this strategy was reduced by 37.3% from 9661,536 l/s in 2010 to 3604,931 l in 2030. For eliminating the deficit of raw water required additional alternative water resources other forms of Ciawi Reservoir and IPA Buaran III.
