The main canal of South-to-North Water Diversion Project enters Baoan Town of Ye County in our city from Fangcheng County of Nanyang, passes through 18 townships in 4 counties, namely Ye County, Lushan, Baofeng and Jia County, and enters Xuchang Yuzhou City after crossing Lanhe River in Anliang Town of Jia County, with a total length of 115.53 kilometers in our city, of which 30.9 kilometers are in Ye County, 42.37 kilometers in Lushan, 20.44 kilometers in Baofeng and 21.82 kilometers in Jiacheng. Baofeng 20.44 kilometers, Jiaxian 21.82 kilometers. Through the size of the river, ditch 113, *** set up more than 200 buildings such as tunnels, culverts, inverted rainbow, bridges, etc., of which the larger crossings are: the river tunnels, Shahe River tunnels, the North Ruhe River inverted siphon project, and so on. The main canal in the city's territory covers a total area of 58,400 acres, of which 24,000 acres of permanent occupation, temporary occupation of 34,400 acres, relocation and resettlement of 4,170 people, the demolition of housing area of 106,900 square meters.

The city's territory of the South-to-North Water Diversion Main Drainage Canal for trapezoidal section, the design of the bottom of the canal width of 25 meters, the depth of water 7 meters, the water-slope slope 1:2 ~ 1:3.5, the back slope 1:1.5, the width of the upper mouth with the topography of the height of the different changes in the water surface width of the water surface width of 60 meters in general. The inner slope adopts cast-in-place concrete slope protection, the outer slope adopts turf slope protection, local slurry masonry slope protection, the top of the embankment is 5 meters wide, the foot of the embankment outside the 5-meter drainage ditch and 8-meter protective forest belt, occupying a width of about 130 meters.

In order to ensure the safety of water quality, according to the State Council South-to-North Water Diversion Office, the State Ministry of Water Resources, the State Environmental Protection Administration and the Ministry of Water Resources, "on the delineation of the South-to-North Water Diversion Central Route Project on the two sides of the trunk canal water protection zone notice" requirements, the non-nullah section (including tunnels, culverts, inverted siphons, water conveyance facilities, such as ferries), a first level of the scope of the water protection zone by the project to the outer boundary line to the two sides of the outer extension of 50 meters, the second level by the first level of the side line of 150 meters. Extension of 150 meters; groundwater level is lower than the bottom of the canal section, the first level of water protection zone by the project management scope of the side line (protective fence network) extended 50 meters, the second level of water protection zone by the side line of the first level of extension of 1,000 meters; groundwater level is higher than the bottom of the canal section, the first level of water protection zone according to the different ways of drainage, the external discharge, the internal discharge section by the project management scope of the side line of the extension to the sides of the 100 meters and 200 meters; second level Water source protection zone external discharge section from the project management scope of the sideline to the left, the right side of the extension of not less than 2000 meters and 1500 meters; internal drainage section of the left, the right side of the extension of not less than 3000 meters and 2500 meters.

The water supply project is planned to set up five water distribution gates in our city, four of which are for the city's Yexian, Baofeng, Jiaxian and downtown water supply, and one for Luohe, Zhoukou water supply. The annual allocation of the city's water supply of 250 million cubic meters, of which 201.7 million cubic meters in the urban area (including 70 million cubic meters in the new city), Ye County 26 million cubic meters, Baofeng 123 million cubic meters, 郏县 0.10 billion cubic meters. The total length of the water supply project pipeline in the city is 74 kilometers, involving 19 townships in 4 counties and 2 districts of Ye County, Rushan, Baofeng, Jia County, Xinhua District and Zhanhe District. The water supply project covers a total area of 3209.38 mu, including 123.58 mu of permanent land, 3185.8 mu of temporary land, and 2613.56 square meters of demolished houses.

According to the preliminary design stage of the estimated budget, the city's main canal and water supply supporting projects total investment of more than 12 billion yuan.

The South-to-North Water Diversion Center Project has brought rare opportunities and challenges for the city's economic and social development, and its far-reaching impact will be gradually revealed in the construction and operation of the project. First, it is conducive to improve the city's total water resources and regulatory capacity, enhance the security of water supply, and promote the improvement of the ecological environment along the route. South-to-North Water Diversion Project annual average allocation of water to the city accounts for about 1/3 of the projected total amount of industrial and domestic water consumption in 2030 in the cities and towns in the receiving area. Second, pulling economic growth. South-to-North Water Diversion Project in the city's annual investment intensity of more than 3 billion yuan, according to the relevant departments of the project construction period of the city's economy will be pulled at least more than a percentage point each year. Third, the project has formed numerous landscapes, and the existing landscape, can further promote the development of tourism and cultural industries along the route. Fourth, expanding labor force employment. According to every 50,000~100,000 yuan investment to create a job estimate, the construction period, the city can increase 30,000~60,000 jobs per year. Fifth, it provides major opportunities for the development of many industries in the city, including construction, building materials, power supply, transportation, catering, tertiary services and real estate development. According to preliminary estimates, Henan Province, the South-to-North Water Diversion Project requires about 2.5 million tons of cement, 445,000 tons of steel, sand and gravel 13 million cubic meters, can directly create profits for building materials enterprises of about 500 million yuan, the province-wide construction tax, building materials tax tax and other taxes of more than 1 billion yuan, the city will also occupy a very substantial share in which.
