Water is one of the basic necessities of human beings to make life and increase their welfare. Indonesia is located in the tropics and have raw water availability. Drought-prone was one problem in the raw water supply as a result of the uneven distribution of water in the region of Indonesia. Tangerang Regency is one of the areas of Indonesia's Banten Province has its challenges in the future to meet the needs of the raw water, due to the increasing population and decreasing ability of the environment both in quality and quantity in the raw water supply. This research aims to know the needs and availability of raw water in the near future. Water demand was analyzed by exponential approximation is a method, and water availability was analyzed based on linear equations obtained from linear regression using Microsoft Excel 2007. Water requirements were analyzed based on demand, such as the water needs for domestic, non-domestic, industrial, fisheries, livestock and irrigation. From the results obtained that level of water needs from 2010 to 2030 as a whole has increased, which for 2010 of 71,61 m3/sec, 2015 amounting to 72,86 m3/sec, by 2020 of 76,24 m3/sec, 2025 of 82,75 m3/sec, and 2030 of 95,35 m3/sec. While the total availability of water from 2010 to 2030 from water source river and groundwater degradation, which in 2010 of 143,17 m3/sec, 2015 amounting to 127,28 m3/sec, by 2020 of 114,02 m3/sec, 2025 of 100,75 m3/sec, and 2030 of 87,50 m3/sec. By 2030 water availability can’t meet water demand, with a water deficit -7,85 m3/sec.
