Wencheng Shanxi Reservoir. The tap water that Wenzhou people eat in 2022 comes from the Wencheng Shanxi Reservoir. The Shanxi Reservoir is located to the west of Shanxi Town, Wencheng County and was built at the end of the 20th century. The Feiyun River flows from west to east here, and the water source is abundant. Therefore, the government decided to build a dam in a relatively narrow mountainous area to the west of Shanxi Town (the upper reaches of the Feiyun River) to intercept and store water. After that, the Shanxi Reservoir It has become a big water tank for the people of Wenzhou.
