On May 13, 2021, The General Secretary inspected the water quality of Danjiangkou by boat in Zhechuan Town, Nanyang City, Henan Province and listened to relevant situation reports.
During the General Secretary's on-site inspection of the middle line of the South-to-North Water Diversion Project, he not only visited the Taocha Canal Head Hub Project, the "faucet" that transports water to the north, but also investigated the Danjiangkou Reservoir and listened to briefings on ecological protection of water sources.
Some people commented that "the success or failure of the South-to-North Water Diversion Project lies in pollution control." In order to vigorously promote pollution control and water quality protection and ensure that water quality meets standards, the Danjiangkou Reservoir Area banned the cage fish farming industry that had lasted for many years, and Nanyang City has closed more than 800 heavily polluting enterprises. It is understood that over the past six years since the water was opened, 95% of the water quality in Danjiangkou Reservoir has reached Class I water quality, and the water quality of the central trunk line has been stable at Class II standards and above, ensuring that the clear water of the river flows northward.
