Doomsday: Humanity shrinks 100 times

Chapter 73 Water System

Although the exploration of this forest area was thrilling, it was still early when the few of them came out, almost around noon.

The people in the shelter have prepared food.

After knowing Zhang Qian's special ability, everyone also experimented with it several times.

After heating the aluminum sheet, Zhang Qian isolates and seals the heat.

When she wanted to use it later, Zhang Qian processed it again, and it continued to produce heat.

With this ability, Zou Yunxin basically no longer needs to be present to boil water or cook.

Zhang Qian was responsible for the canteen work. She had the most experience in the kitchen among the few people. More importantly, she could control the "heat", that is, the degree of heat released by the aluminum sheet.

This will increase the heat utilization rate sharply.

The food for lunch was naturally walnut porridge again, but there were some green particles in it, which should be some wild vegetable leaves added.

The wild vegetable still looks a little wilted, but this is normal. As long as the soil remains moist, there will be no problem.

The people in the shelter breathed a sigh of relief when they saw Lu Yuning and Wu Xiao return.

The main thing is that even though Xu Qi is here, the forest area still seems to be full of dangers, so we have to worry.

Fortunately, several people still have confidence in Lu Yuning, and it can even be said that they believe in him blindly.

"We harvested a lot this time. We brought back a lot of walnuts, and we also have new ingredients. We don't have to worry about food problems in the short term." Lu Yuning announced.

Seeing everyone's happy expressions, he cleared his throat and continued, "After the food problem is solved, we need to consider the next step of construction, so I still want to discuss with everyone to see which one has a higher priority."

Everyone immediately started discussing it. Xu Lele was still a little shy because she had just joined in, and she naturally knew nothing about the construction of the shelter.

Zhang Xinyue and Zhang Qian were more attentive, afraid of neglecting her, and would talk to her from time to time.

"Le Le, is there anything you want? Brother Yuning can get it for you." Zhang Xinyue touched Xu Lele and said.

Lu Yuning smiled but said nothing.

"No, this place is better than the pavilion. The food is good, the accommodation is comfortable, and my brothers and sisters are all very nice." Xu Lele shook her head and answered truthfully, looking a little well-behaved.

Everyone liked her, mainly because she was really well-behaved, quiet, and sweet-talking. With the addition of children in the shelter, the average age of the children dropped, and the atmosphere inexplicably felt a lot more lively.

"Since no one has mentioned it, I won't be polite. I want a shower room." Zhang Xinyue was the first to put forward the request.

Zhang Xinyue had been thinking about the shower room facility almost since the first day after she was shrunk, but Lu Yuning's ability was indeed limited.

But now it's something to consider.

"We can consider this now. Hygiene and cleanliness are a big problem. Although our hygiene situation is not as serious as in the pavilion, it is indeed uncomfortable not being able to take a shower for a long time." Lu Yuning nodded in agreement.

"But the amount of water is a problem, right?" Zhang Xinyue said.

"Well, taking a bath is different from cooking and washing up. The amount of water used each time is quite large. Moreover, there are six of us now. I'm afraid that after each of us takes a bath, the water outside will be gone." Lu Yuning said.

He paused and continued, "So before that, we have to consider the construction of the sewer system."

Everyone nodded.

Lu Yuning has mentioned the idea of a water system several times, and everyone is aware of it.

Moreover, the reason why we worked so hard to build the sewage system first was actually because we took into consideration the construction of the water system later.

As the name suggests, a water system is an overall device for utilizing water.

Of course, this is easier said than done, but there are actually many things involved.

The water system includes the water supply system, water delivery system, and water resource system. The water supply system can be understood as a complex system of reservoirs, water pumps, pipelines, and other projects.

Of course, given their current height, abilities, and water consumption, all they need to do is build a large water tank.

As for how big it should be, theoretically the bigger the better, but we should mainly consider their current water extraction capacity and material usage, so we also need to make actual calculations when doing it.

Another key issue is the water intake capacity, that is, the water pump. How to bring river water into the water tank is an important issue.

So the water tank and water pump are the first problem they need to solve, otherwise everything else is just wishful thinking.

In addition to the water supply system, there is also a water delivery system.

This is also easy to understand. After there is water in the water tank, pipes need to be laid to various facilities with water needs to transport the water and install control devices such as valves and switches.

Of course, this also includes filtration, water treatment, etc., and the amount of water required for each facility is also different.

For example, it is better to filter the water leading to the kitchen before use, and the same goes for the bathroom.

The bathroom can use sewage directly.

The final water resource is the recycling of some water. For example, kitchen water can be treated and then used in the bathroom.

Or it can be transported to irrigation ponds for cultivated plants.

Therefore, this water system is a very complicated task. It is basically impossible to build it successfully in one go. We need to make a good plan first, do it step by step, and get the most basic things done first.

So the first step is to make the water tank and water pump.

The water tank is relatively simple, it is mainly a matter of materials, and the rest is just the workload.

As for materials, Lu Yuning would definitely have to go to the trash can again and get some back.

He planned to use wood material for the outside of the water tank, which could be made thicker so it would be more stable, and then put a layer of plastic inside.

This way, a lot of materials can be saved. The remaining materials will be used to make water pipes, which is the biggest material consumption.

The main thing is that if you want to use a water pump to pump water from the river, you also need to make a plastic water pipe about six or seven meters long to lead it to the river.

In order to ensure airtightness and oxidation resistance, plastic needs to be used, but bamboo is also an option.

The last step is to make the water pump.

Of course, you can also consider using a water truck to transport the water up.

But this thing is more difficult for them, mainly because the river is located in a lower terrain.

In order to transport water up, the waterwheel must be built very high, which is almost an impossible task for them.

Therefore, the steam system is a better choice. It requires more technological means and relatively less labor.

However, Lu Yuning didn't know much about the steam system. He only knew some of the uses of the steam engine, but he didn't really understand the details.

Fortunately, Zhang Xinyue is very clear about this.

This invention is a landmark one. It not only concerns the construction of water systems, but if it can be made, it also means that everyone has officially entered the steam age.

Some simple steam-driven mechanical devices can also be studied.
