In 1997, TDC undertook the work of designing and constructing of contaminated bed-silt treatment phase-I at Caohai of Dianchi Lake in Kunming Yunnan, the first inland river-lake environmental dredging project in China. Dianchi Lake, known as “Plateau Pearl”, is a famous plateau fresh water lake in China, which is divided into Waihai and Neihai by embankment and the Neihai is Caohai. The water in Caohai of Dianchi Lake is crystal clear after its contaminated bed-silt being dredged by cutter suction dredger.
