Wu Guangliang also knows that under the current situation of large-scale environmental protection across the country, even if Minsheng Company can bring very large benefits to the local area, it is impossible for the government to take such a big political risk and open up to Minsheng Company.

Moreover, if the power of shared space is used to send the excavated earthworks to other places, anyone with a little knowledge of earthwork can easily see the problems.

Therefore, in the densely populated hinterland, only a means that normal people can understand can be used to solve the problem of disposing of these muck soils.

In fact, when Yunmengze was built in another world, due to the low terrain, the Yunmengze area, which was sandwiched between the Yangtze River and the Han River, was vulnerable to flooding.

In order to achieve this once and for all, Wei Minsheng adopted the practice of building sewers directly on the original ground and greatly improving the city's foundation.

Although this method has a large amount of filling, it reduces the excavation work on the urban foundation, and at the same time leveling the mountainous land that obstructs traffic, which seems to be a more reasonable choice.

Now Wu Guangliang's situation has some commonalities with this, and it is completely possible to use the fill as a way to digest the muck produced by leveling the ground.

Moreover, in Wu Guangliang's plan, this new city should have a relatively isolated environment from the surrounding environment, and a relatively large drop is also a good choice.

Only in this way will the new city have the opportunity to show the world how it is different from other places in terms of management.

The two square kilometers of ungraded land allocated by the government to Minsheng Company were originally the largest terrain difference in the planning area, but the government delayed leveling it because of the large funding gap.

An area that is approximately rectangular, with a shallow hill twenty or thirty meters above the county road on one side and a huge depression on the other.

Such terrain is very common in the shallow hilly landforms around the basin.

Due to the local water shortage, a weir pond is generally built in the depression for irrigation of paddy fields in the flatter areas around the depression.

In the past, when there was abundant labor, the surrounding higher terrain area was a small piece of dry land, and only some drought-tolerant crops such as corn, wheat and red vetch could be grown.

However, such soil clods have a large slope and are not conducive to mechanized farming.

In the case of higher and higher labor costs, this way of farming hardly makes any money, and it is better to earn more than to go out to work.

Nowadays, urban development is increasingly limited by the number of residents, and the demolition and relocation work in the surrounding area is almost at a standstill.

So, in the case of a massive labor outflow, these places have actually been abandoned long ago.

Compared with the annual circulation fee of only 3 to 500 yuan per mu in places farther away from the city, it is a better choice to give up the right to contract land in exchange for social insurance for urban residents.

The low cost of land acquisition is also an important reason why the government has agreed to allocate the area to Minsheng Company for development.

Because with the further improvement of the ability of the surrounding cities to absorb the population, the continuous decline of the county's population has become an irreversible process under the current circumstances.

With the vacancy rate of housing in the county getting higher and higher, it has been a long time since a new developer has moved in.

The few existing developers are all because there are still some unfinished properties that have not been completed many years ago, so they have left some people here to "continue their lives".

In fact, in Wu Guangliang's view, the land allocated by the government to Minsheng Company is still ideal.

Because the scattered buildings on this land have already been demolished, at least the construction of the new city will not be hindered by "nail households".

The new city is still planned as an urban unit, with a large number of irregular plots left around the area of the two square kilometres after a single urban unit has been planned for a higher area.

Because the local water resources are not abundant, if the residents living in the new city have to control their daily water supply by the local government, Wu Guangliang will not have relatively independent management rights in the new city.

This depression covers an area of more than 100,000 square meters, and if this depression is converted into a reservoir, even if the average water storage depth is only five meters, it can theoretically provide a volume of 500,000 cubic meters, which is equivalent to reaching the standard of a small type II reservoir.

As the depth of water storage increases, the volume of the depression will become larger and larger, and it is not impossible to meet the standard of a small type 1 reservoir.

However, under the current system, the construction of reservoirs requires layers of approval, and it is impossible to approve them in a short period of time.

Because to build a reservoir under normal circumstances, it is definitely necessary to make use of the terrain and the river.

Moreover, the existence of the reservoir may have an impact on the ecological environment of the reservoir basin, and it is necessary to conduct an environmental impact assessment and make a feasibility report first.

It is clear that the construction of a reservoir in an area where there are almost no rivers is not something that a normal person can imagine.

Therefore, Wu Guangliang did not treat the depression at all, and only built an urban domestic sewage treatment plant in a higher position around the depression.

This sewage treatment plant mainly treats the domestic sewage generated in the new city, which can be directly piped into the sewage treatment plant due to the higher terrain of the new city.

At the same time, after connecting the sewage treatment plant contracted by the Minsheng Company near the original county town through the pipeline, the two sewage treatment plants can be connected to the grid.

When there is a lot of domestic sewage, two sewage treatment plants can work at the same time to increase the sewage treatment capacity.

When there is less domestic sewage and a sewage treatment plant needs to be overhauled, only one sewage treatment plant can be operated to reduce operating costs and improve operating efficiency.

Of course, as long as Wu Guangliang is here, there will definitely be no shortage of "sewage" produced in the new city every day.

A large amount of treated "grey water" cannot be discharged casually, right?

Therefore, the weir pond located under the sewage treatment plant has naturally become the "reclaimed water" reservoir of the sewage treatment plant.

If the reservoir is too small to hold the "grey water" treated by the sewage treatment plant, some of the surrounding abandoned paddy fields can be diverted.

As for the extent to which the "reclaimed water" in this depression will be stored, only God knows.

Therefore, Wu Guangliang did not explain the use of this depression in his external planning.

There are no conditions for building a reservoir here, but if the treated "reclaimed water" naturally forms a large "pond" because of the treatment of urban domestic sewage, the local government is also optimistic. 2k reading web
