After rectifying the order of water and land transportation in the whole city, Guan Ping and Gao Liang, the Qi pipe experts invited by Dai Yan from Linzi, finally made the plan for flood control and sewage discharge in the entire Taoqiu. Pen ~ fun ~ pavilion www.biquge.info

These two people are worthy of inheriting the mastery of pipes, and they are indeed unique in the city's sewer planning!

In their plan, if they want to make the whole Taoqiu free of any flooding, and the perfect solution to the city's waterlogging problem, it is to build a whole system of channels flowing through Taoqiu.

In order to make the whole channel system can be used perfectly, in addition to the ditch in Taoqiu City is wide enough, it is also necessary to form a huge water level difference between the entrance and exit of the entire channel, and use this huge water level difference to make the ditch in Taoqiu City become a continuous stream of living water, forming a river that flows like Jishui!

Therefore, they suggested that Dai Yan first build a reservoir near the upper reaches of the Jishui in Taoqiu, connect the reservoir with the pipeline in Taoqiu City, and then continue to connect the end of the pipeline to the downstream of the Jishui. In this way, the canal system in the entire Taoqiu City has become a branch of the water, unless the entire Jishui is flooded and becomes the ocean downstream, otherwise Taoqiu will not have any more floods!

Of course, in order to prevent this possible flooding, they also suggest that it would be better if there was a perfect diversion tank downstream.

And after they carefully inspected the terrain near the entire Taoqiu City, they found that there was no shortage of this reservoir and water guide pool!

In the upper reaches of Taoqiu, only three or four miles away from the city, there is a small lake with a radius of three or four miles, which should have been a depression formed by the flow of water through this place, so it was called Ozawa by the locals. However, after so many years of development, the connection between Ozawa and Jishui has been cut off by farmland, and the small lake is now only used by farmers to catch some fish and turtles, and the whole lake is gradually shrinking, and it may not be long before the small lake will dry up completely.

As for the downstream water diversion tank, it has a unique place. This is the famous Heze in this era and in later generations.

Heze is one of the ancient nine Ze, also known as Lei Ze, Meng Zhuze and so on. It is said that the ancestors of China, such as Fuxi, Yao and Shun, have all been active here, and it is one of the origins of Chinese civilization. In today's era, it is a large lake that is fifty or sixty miles long from east to west and about ten miles wide from north to south.

It is connected to Jishui to the west, while it is connected to Surabaya to the east by the Heshui River excavated by the Song Kingdom. Considering that it communicates Jishui and Surabaya, on a large scale, it communicates Huaishui and the big river, and it can be regarded as a transportation artery for water transportation. And it is precisely by virtue of this water transportation artery that Taoqiu can become the commercial center of the world!

If Jishui, Xiaoze, Taoqiu Chengyi and Heze can all be connected, then Taoqiu will have a whole living channel system. With the help of this channel system, Mo said that the entire Taoqiu city will be connected in Heze, so that there is no longer any need to worry about the waterlogging of the city, and there is no need to worry about Taoqiu using water to destroy the city when it encounters a foreign invasion, and all the sewage in Taoqiu City can be discharged!

There is such a vast area of Heze downstream, plus it is connected to the Surabaya River and Huaishui River downstream, its ability to treat sewage must be extremely strong! As long as the population of Taoqiu does not reach the level of tens of millions of people in later generations, I think that relying on Heze itself will be able to purify the sewage of the entire Taoqiu!

Such a project in one fell swoop is really worthy of being the only remaining water conservancy expert in Qi Guan!

However, Dai Yan saw farther than these two water conservancy experts, and in his opinion, since such a channel could prevent waterlogging and discharge sewage, why not add another purpose?

In fact, there is no other purpose for Dai Yan to add, which is to supply tap water.

The invention of tap water actually existed a long time ago. For example, Rome, which existed in the same period as the current Warring States Period, already had running water at this time. Unfortunately for the Romans, most of the pipes used in their water system were lead, and they did not know that this thing was toxic to the human body. Lead is a heavy metal that is a chronic poison, and the accumulation of too much in the human body will inevitably lead to the deterioration of the body, and lead poison will affect the rest of the person! Because of the use of lead water pipes, generations of Romans paid a heavy price with their lives.

This had a significant impact on the decline and fall of the Roman Empire. Think about it: the aristocracy of a country, the average life expectancy of the ruling class is not more than forty, and the life span of this country is likely to be long?

However, Dai Yan is not worried about these at all, because China has a natural and good water pipe: bamboo!

Bamboo is indeed one of nature's best gifts to Chinese civilization, and its uses are so extensive! Its seedlings and bamboo shoots can be eaten, its young stems can be extracted from fresh bamboo to make medicines, and its finished products can be burned and woven into bamboo furniture.

Its greatest influence on Chinese civilization was its two uses: to make bows and arrows and to make bamboo slips.

It is said that Dongyi, who are completely integrated into the Chinese civilization, is because they are good at archery. And the reason why they are good at shooting is because the Dongyi tribe has the habit of planting bamboo, and they have the best bows and arrows in the world!

In the Spring and Autumn Period, the Warring States Period and even the Qin and Han dynasties, the great development of Chinese thought was because people invented the excellent writing material of bamboo slips! Today, even though Dai Yan has invented paper and marketed it all over the world, many countries still use bamboo slips as writing materials. It can be seen that how important is the status of bamboo in Chinese civilization?

And Dai Yan's idea of using bamboo water pipes was not a whim, because in later Song and Ming and other economically developed dynasties, the Chinese had already used this kind of bamboo water pipes.

Of course, since Dai Yan wants to build a strong tap water supply system, he does not want the bamboo pipes to be corroded, or the water pipes to rupture due to human factors, resulting in a waste of water sources, which in turn affects the water supply of the entire city. To do this, he referred to one of the most advanced water supply systems of later generations: the Edo Water Supply System in Japan.

During the Tokugawa Shogunate period, Edo was the seat of the shogunate, and it was almost the capital of Japan. In order to make Edo the most developed city in Japan, the Tokugawa family put great effort into flood control and the supply of fresh water to Edo, and their achievements are remarkable.

They built the famous "Kanda Pipeline" near Inokashichi Pond, the main water source of Edo. The principle of the Kanda pipeline is similar to the principle of the Taoqiu waterlogging treatment by Qi Guanzi experts today, and the waterway is circulated to supply water due to the difference in water level. They used a barrage to hold back the water and raise the water level, and then built a waterway near the Kanda River that flowed through the shogunate and all over Edo, and then piped the water near the waterway to supply the residence and the city, and the end of the waterway was diverted through the river, so that the entire city could have a clean water source.

The results of such a water supply system are truly impressive. In the 17th century, whether it was the city of the Qing Dynasty or the London and Paris of Europe, everyone had to bathe by the river, and when they ran to the river to get water, the people of Edo could already use clean tap water.

Even in the 18th and 19th centuries, when Edo's population grew rapidly and exceeded one million, the shogunate simply added a similar Tamagawa pipeline to the Kanda pipeline, and the city no longer had to worry about the lack of water. This shows how advanced Japan is in this regard!

Although the design principle of this waterway is simple, it can withstand the test of time because it allows the water to flow naturally due to the difference in water level. It is the Kanda pipeline, which has a simple principle, that produces a water supply system that has been used in Japan for hundreds of years and can continue to be used!

Nowadays in Taoqiu, if Dai Yan wants to use such a tap water system, it is actually very simple, it is nothing more than dividing the pipes to be excavated in Taoqiu City into two parts, one part is used as a sewage pipe, and the other part is used as a water pipeline. Sewers can be connected to homes by ditches, etc., while water pipes can be connected by bamboo pipes. The two sides flow in parallel without affecting each other!

According to this scheme, there is another big advantage: because there is an additional water channel in Taoqiu City, in the event of a flood, the speed of water flow in Taoqiu City to the outside of the city will also be greatly increased!

If the waterway project designed by the two Qi pipe experts can resist a flood that occurs once in 50 years, then the design modified by Dai Yan can at least resist a flood that occurs once in a century!

There are so many benefits to adding a waterway, Dai Yan admires himself a little, it's a pity that he doesn't go to water conservancy projects!

The only drawback in the installation of a drinking water pipe is that the project in Taoqiu City is doubled. Unfortunately, once such a water system is designed, it will be a purely public project, and the eup will not be able to reap any real benefit from it.

Forget it, it's a feudal monarch who owns the world's first commercial city, and it's not so much money! Dai Yan comforted himself like this. Moreover, if we can improve the happiness of the residents of the whole city through such public services, and attract more talents from all over the world to come here, it will also be a more long-term benefit!

So after Dai Yan discussed his ideas with the two Qi pipe experts, Dai Yan handed over the general project of flood prevention, sewage and water supply to the two experts for the entire Taoqiu.

Dai Yan set aside some of the transformed rangers as cleaners to maintain the cleanliness of the city streets under his rule by the district governments, and he handed over all the rest to two experts to complete such a project!

Later, Dai Yan thought that the progress of such an important project was too slow, and recruited ordinary people throughout Taoqiu City to help complete the project.

For such a project, Dai Yan can actually be completed by levying and issuing conscription. However, in his opinion, if the common people spend countless hours and let them work here for free, these common people must not be highly motivated. Instead of this, it is better to pay some money to work with peace of mind for the common people, and the progress of completing the project will be greatly accelerated. And distributing the wealth he has accumulated to the hands of the low-level common people in this way to help them become rich can also show his benevolence of Tao Qiujun.

As Dai Yan expected, when he later accelerated the largest project of Taoqiu by recruiting migrant workers, this magnificent project was completed in just two years! After the completion of this project, whether it was these ordinary people, or merchants, or scholars and travelers who flocked to Taoqiu from all over the world, everyone praised his kindness!

Engaging in such a big project has not been as infamous as Emperor Qin Shi Huang and Emperor Yang of Sui at all, and in such an era, it has to be said to be a miracle!

After Dai Yan rectified the entire Taoqiu through various means, the entire Taoqiu became clean and tidy, the city was safe, and people's lives became orderly. These changes made Dai Yan finally see the shadow of the modern city of the later generations on Taoqiu City, and the entire city under his governance was slowly praised by the people!

More and more people are moving to this well-ordered city, and the whole city is becoming more and more prosperous!
