History

Guanting Reservoir started construction in October 1951^[7] and was completed on 13 May 1954,^[8] with the main flow of water being the Yongding River in Huailai. The reservoir covers an area of 230 square kilometers and has a total storage capacity of 2.2 billion cubic meters.^[9]

Guanting Reservoir was a major source of fresh water for Beijing^[10] and neighboring regions.^[11] Due to water contamination, the reservoir was withdrawn from the system to supply Beijing with drinking water in 1997,^[12] but after thorough treatment, the reservoir has been an alternate water source since 2007.^[13]
