Chinese archeologists have discovered a large water project dating back about 5,000 years in east China’s Zhejiang Province.
It’s the oldest large water system ever found in China.
The finding, which includes 11 dikes, is located on the outskirts of Hangzhou, capital of Zhejiang.
It is believed to have combined functions of flood control, transportation and irrigation.
Archaeologists discovered the water project while excavating the Neolithic remains of the ancient city Liangzhu that existed about 4,500 to 5,300 years ago, which was discovered in 2007 in Hangzhou’s Yuhang District.
High dikes erected along the mountains and low ones linking the mountains may have formed three reservoirs, one apparently covering 9.4 square kilometers — about 1.5 times the area and four times the volume of Hangzhou’s iconic West Lake.
