The Wandan Canal provides irrigation for farmland in Wandan and Xinyuan Townships, Pingtung County. Constructed in 1928, it draws water from the Gaoping River to irrigate 1,500 hectares of farmland. In recent years, efforts have been made to enhance the ecological environment along the canal. The management and maintenance of the water facilities have shifted toward creating greener and more aesthetically pleasing surroundings. To support the government's green energy policy, solar power systems have been installed along the canal's banks, maximizing the multifunctional use of the water resource land.
