Bed-Silt Dredging Phase-II for Xihu Lake of Hangzhou

TDC adopted the long-distance construction by way of multi-stage pumps in series with the environmental dredger transporting, through 7-stage booster stations, contaminated bed-silt to the outskirts 22.6km away for harmless treatment, setting a domestic record of the longest discharging pipeline. On completion of the works there were no high, missed or over-dredged spots in the working area and the years-long contaminants in bottom sediment were thoroughly cleared with undisturbed soil remaining the same.
