How to exempt 200 million people from paying water transfer fees, and ensure that nearly 100,000 water conservancy people have an average annual salary of 300,000 yuan?
The Ministry of Water Resources has announced that the average annual salary of employees in the subsidiary companies of the South-to-North Water Diversion Project is as high as 28830,000 yuan. See below for details.
Remarks:1The total amount of wages payable refers to the total amount of labor remuneration payable to the on-the-job employees of the enterprise during the reporting period, including wages, bonuses, allowances, subsidies, overtime wages, wages paid under special circumstances, etc.
The wages of employees of the South-to-North Water Diversion Project mainly come from the water transfer fee, according to the South-to-North Water Transfer Water Price Mechanism. The annual income of the East Central Route of the South-to-North Water Diversion Project is more than 10 billion yuan, of which the water price of the water diversion can reach up to 25 yuan per ton. The average water price should be more than 1$5. More than 10 billion tons of water are transferred annually.
This money is provided by the people of the North China Plain, and the price of water is not high for many wealthy people in Beijing and Tianjin who have tens of millions of real estate assets per household. But the majority of ordinary people pay nearly 100 yuan a month for water, which is a bit expensive.
If the South-to-North Water Transfer Project can be exempted from water transfer fees, it will benefit nearly 200 million people.
How to exempt 200 million people from paying water transfer fees, and ensure that nearly 100,000 water conservancy people have an average annual salary of 300,000 yuan?
The answer is: efficient use of water resources and low-cost expansion of the middle route of the South-to-North Water Diversion Project.
First of all, it is necessary to make full use of the existing water conservancy facilities, and invest more than one trillion yuan in the Three Gorges Reservoir, the Hanjiang River Basin, the Huaihe River Valley, and the Sanmenxia Xiaolangdi Reservoir. How to balance the use and maximize the economic benefits of the existing water conservancy facilities is the key to the expansion and low cost of the middle line.
All water conservancy facilities are used to ensure the production and domestic water supply of people in Xiangyang, Wuhan and other places in the lower reaches of the Han River.
How much water do they need?According to relevant statistics, the water used in the lower reaches of the Han River does not exceed 10 billion cubic meters, and if it is too much, it will cause flooding.
To this end, 40 billion cubic meters of water resources from the Hanjiang River are intercepted in the Danjiangkou Reservoir all year round, and more than 60 billion cubic meters of water resources in good years are transferred to the Huai River and the North China Plain.
The water used in the lower reaches of the Han River mainly comes from the 6.8 billion yuan diversion project to supplement the Han River, and the annual runoff of the North River in the South River is 3 billion, plus rainfall in the lower reaches of the Han River. Enough water for the Han River basin.
Of course, the water shortage in the lower reaches of the Hanjiang River can also be opened at the mouth of the Danjiang River to release water, when the construction cost of the project is **, you can also consider allocating all the collected water to the people in the lower reaches of the Hanjiang River, assuming that 1 yuan per ton of water, the annual income of 40 billion yuan is evenly distributed to the people in the lower reaches of the Hanjiang River, and each person can get thousands of yuan.
The project of diverting the river to replenish the Han River is already under construction, with an investment of 60 billion yuan, and the water and electricity charges of the Nanhe River have been changed to pumped storage, turning the entire river basin into a reservoir. Probably more than 3 billion cubic meters.
When the people in the lower reaches of the Han River agreed to transfer water, the Danjiangkou reservoir will be expanded to 36 billion yuan, and the Huaihe River basin reservoir will be expanded to 12 billion yuan. The upper reaches of the Yellow River use 25 billion yuan of storage capacity in Housanmenxia and Xiaolangdi, which is more than 60 billion yuan, which is enough for the annual water demand of the North China Plain.
With water, how can the middle line be blended and expanded?
According to the current South-to-North Water Diversion Project, the direct expansion of the existing route is a huge investment, and the cost of land acquisition alone is very high, and the water head gap between the Danjiang Estuary and the north bank of the Yellow River is insufficient.
Is there any way to make the most of the water head in the existing reservoir?This is the key to low-cost expansion, with sufficient head to increase the speed of water flow, and low-cost tunnels to divert water in a straight line.
Figure 1: The middle route of the South-to-North Water Diversion Project has been expanded to 40 billion tons, with an investment of about 55 billion yuan.
How can the tunnel achieve a diameter of 16 meters and cost only 300 million one kilometers?See details for detailsThe TBM tunnel, which reduces the cost by 75%, is a powerful tool for the energy revolution
In addition, 45 billion yuan will be invested to transfer water resources from the Huai River to the north bank of the Yellow River, which will reduce unit construction costs due to the abundance of water heads, which can speed up the flow of water and reduce unit construction costs.
In other words, we used the flood of the Han River to replace the reservoir capacity and water resources in the upper reaches of the Huai River basin.
Another issue of making full use of existing water conservancy facilities is whether to use water or electricity
The existing water conservancy facilities have only two functions: power generation and water conservancy, and we will build photovoltaic power stations with the same power generation scale to compensate for the existing water conservancy facilities and maximize the effect of water conservancy. It can maximize the use of resources.

The adjustable water volume written in this article is the historical average, and the water released by the reservoirs in the upper reaches of the Yellow River is mainly relied on in dry years. Flood can be discharged in a good year, but it will not cause flooding.
