Ci Durian (Durian River), or Ci Kandi, is a river in the Banten province of western Java, Indonesia. It rises in the mountains to the south and flows north to the Java Sea.The delta of the river, now canalized, has long been used for rice paddies and for a period was also used for sugarcane plantations.Extensive irrigation works diverted water from the river into a canal system in the 1920s, but these works were not completed and suffered from neglect in the post-colonial era.Plans were made in the 1990s to rehabilitate the irrigation works and dam the river to provide water for industrial projects, with Dutch and Japanese assistance, but these were cancelled by the Indonesian government.
