In May, the warm spring has gradually left us, and the cheerful Water of the Yangtze River runs north along the main artery of the East Line of the South-to-North Water Diversion Project, bringing happiness and hope to the economy and life of people along the project.
"Before drinking the water of the Yangtze River, people drank groundwater, which contained a lot of fluoride, and villagers generally had yellow tooth disease and heel pain. Since the South-to-North Water Diversion Project came over, the Yangtze River water has been used, and the taste of the Yangtze River water is good, there is no scale, and the crops grow well. Speaking of the south-to-north water diversion, Zhang Jinyun of Pangzhuang Village in Haowangzhuang Town, Wucheng County, Dezhou, Shandong Province, could not suppress it.

Wucheng County is located in the northwest of Shandong Province, downstream of the Wei Canal in the Haihe River Basin, at the end of the Yellow River. The county has a large area of bitter water, fresh water area of about 334 square kilometers, accounting for only 44.7% of the total area of the county, the total amount of shallow surface water of the average water resources for many years is 52.027 million m³, the available amount is 44.866 million m³, the per capita occupancy is 140 m³, only 6% of the national per capita share, shallow groundwater is brackish, the deep groundwater fluoride content is as high as 4 ~ 6 mg / L, is a typical groundwater fluoride exceeding the standard county, the people drink high fluoride water for a long time, dental fluorosis, skeletal fluorosis and other diseases, It causes great harm to the health of the body. With the rapid development of cities and industries, the demand for water is getting larger and larger, forming a regional water level decline, becoming a local deep funnel in the deep water funnel of Dezhou City, with an area of about 500 square kilometers, in addition, with the emergence of problems such as unreasonable water structure, water resource utilization rate, and serious water pollution, it directly restricts the development of the local economy.
At the end of 2015, the water of the Yangtze River entered the waterworks from the Wucheng Datun Reservoir, and Wucheng County became the only county in Dezhou City with the "dual water source" of Yellow River water and Yangtze River water. "The amount of water supply has been guaranteed, saving the Water of the Yellow River for agricultural irrigation, and ensuring the safety of drinking water for residents in the county." Zhang Lei, secretary of the Wucheng County Party Committee, said.

Datun Reservoir is one of the reservoirs in Shandong province of the South-to-North Water Diversion Project, located on the east side of TheWa of Enxian County, Wucheng County, Dezhou City. The reservoir dam is roughly quadrilateral, with a total area of 9732.9 acres, a total length of 8913.99 m in the axis of the dam, a maximum design storage level of 29.80 m, a maximum reservoir capacity of 52.09 million m³, a design dead water level of 21.00 m, a dead reservoir capacity of 7.45 million m³, a regulated reservoir capacity of 44.64 million m³, and the water quality in the reservoir is stable to meet the surface water class III standard. The main task of The Datun Reservoir is to divert the yangtze River water to supply water to urban residents and industries in Decheng District of Dezhou City and Wucheng County, and the annual water supply to Dezhou City is designed to be 125.02 million m³, of which the annual water supply to Decheng District is 109.19 million m³, and the annual water supply to Wucheng County is 15.83 million m³.
In May 2015, the Wucheng County Water Supply Project of the South-to-North Water Diversion Project was completed, and the drinking water source of the residents of Wucheng County was replaced by the water of the Yellow River to the water of the Yangtze River, and up to now, a total of 36.35 million m³ of Yangtze River water has been transferred from the Datun Reservoir to Wucheng, effectively alleviating the situation of water shortage in the county. Not only that, Wucheng County also invested 36 million yuan to upgrade the waterworks, so that the water supply capacity of the waterworks increased from the original daily water supply of 20,000 tons to 40,000 tons, using the country's leading flocculation precipitation filtration and deep water source treatment technology, completely solved the problem of excessive fluoride content in drinking water in Wucheng, and realized 24-hour uninterrupted water supply in urban and rural areas, covering the county and 393 administrative villages, so that more than 400,000 residents in the county can drink safe, hygienic and healthy water at any time. The surrounding groundwater resources and water environment have also been continuously improved.

The water from the south is slowly injected into every household in Wucheng County sweetly, and then quietly enters the life of the locals, changing the history of local people drinking high-fluoride brackish water for thousands of years, and the people's sense of gain, happiness and security continues to increase.
"Say goodbye to brackish water and eat sweet water, beautiful!" Since the datun reservoir project on the eastern line of the south-to-north water diversion project has been supplied, this has been a common phrase for the local people. (Zan Shengguang)
