<p align="justify">Tanjung Lesung in Pandeglang, Banten Province is a strategic national zone that has been determinde as Special Economic Zone (SEZ). Its development becomes a tourism SEZ can affect the increasing of water demand either about water quality or quantity. Meanwhile, water availability is finite. This project studied about designing of long storage in Ciliman watershed especially to fulfill water demand in Tanjung Lesung SEZ. Water availability is analyzed by F.J Mock method and the result showed that maximum discharger is occured in February while minimum disharge is in August. Water demand that would be calculated is water demand in domestics, irrigation, airport and Tanjung Lesung SEZ. Then the water availability and water demand was simulated in WEAP to obtain the distribution pattern. According to the result, Tanjung Lesung SEZ water demand can not be 100% coverage. Water demand coverage is optimized by managing water supply to irrigation site and adjust its crop intensity. Then, to enhance Tanjung Lesung SEZ water demand coverage there would be designed a long storage, its volume is 72,760 m3 and the length is 650 m. It is also design with a round weir 3 meters high and completed by bucket type stilling basin. Estimated cost to design and build the long storage is Rp13,643,002,221,-.<p align="justify">
