How did the ancients ensure the safety and cleanliness of drinking water?

In ancient times, people used water very strictly, because it was very difficult to drill wells at that time, so drilling wells at home was impossible. At that time, people would find a good place to dig a well and use it together, but for those who were drawing water at that time, some people were watching the water because they were afraid that someone would draw more water or break the well. Every time they take water, there is a certain amount of water. They were very strict in this respect, indicating that people were very strict in the management and use of water at that time.

In ancient times, it was difficult for every family to have a well, because ordinary families did not have the corresponding well-drilling tools, which led to many people being unable to drill wells. Not enough people can't dig a well by themselves. Even if you can dig a well yourself, you will hand it in, because the regulations at that time did not allow it to be confiscated as soon as it was discovered, which made many people give up the idea of digging a well.

Although we can't dig a well ourselves, our water can still be guaranteed. After all, water resources were also very important at that time, and water should not be wasted casually. We used to use water for a long time, and the wells we dug for a long time ran out of water, so people at that time were more cautious about using water, and I'm afraid there was no water either.

In order to ensure water supply, the ancient city also attaches great importance to the planning and construction of water supply facilities. On the site of Yangcheng in the Eastern Zhou Dynasty excavated by 1977, we found the urban water supply facilities that are not backward today: ceramic water supply pipes are buried underground, with pools and valve wells. After the grit in the clarifier is clarified, it will enter the city for residents to use.

In some dynasties, the royal family also set up special water sources for special water supply. For example, in the Yuan Dynasty, the spring water of Yuquan Mountain was collected by digging Jinshui River. It was introduced from the south gate of Heyimen (now Xizhimen). It flows through the palace and then enters the Taiye Pool, which is the drinking water source of the imperial city and the water source of the palace.

The construction of water supply facilities is to improve the supply and guarantee of drinking water from hardware and strengthen management from ancient "software". Every dynasty set up a special "water officer" to be responsible for water resources and water security. The "Great Wall of Water" in the Han Dynasty, the "Horizontal Platform" in the Western Jin Dynasty and the "Water Supervision" in the Sui and Tang Dynasties are also their responsibilities to ensure urban water supply.

In any case, we should pay attention to the protection and utilization of water resources and ensure that there is water when using water, which is of great benefit to our lives, so we must never waste water resources.
