My Doomsday Shelter Unlimited Upgrades

The rainwater collected on the roof is relatively clean, with few impurities and sediment, and it can be directly connected to the water storage system.

As far as the only disadvantage is, it may not be able to collect so much rainwater. After all, Chen Yang only has one roof.

But this shortcoming is also a bit out of thin air, and it means to be dark.

In fact, Chen Yang doesn't care about how much water there is or how little it is. It's already an icing on the cake just relying on one roof to collect it.

After thinking about it, Chen Yang climbed to the roof through the outdoor Jackie Chan happy ladder.

The location of the roof collects rainwater, and the method is also very simple.

Raise the corners of the roof a small distance to form a groove at the roof.

Cut a pipe in the corner of the roof, and this pipe can be connected directly to the tank.

Before the end of the world, almost all modern residential buildings will have such pipes.

At the lower end, the pipes are directly connected to the first floor, and the rainwater is directly directed to the ground.

On the higher end, the pipes connect to an underground rainwater collection system.

Of course, Chen Yang wants to be a bit more high-end.

The life of a human being begins with rainwater collection!

Since the shelter itself was made of stone, Chen Yang did not use concrete for the installation, which would appear too abrupt.

After using 10 units of stone materials, Chen Yang installed a stone fence nearly half a meter high around the roof.

In this way, whether it is water collection or from a safety point of view, there is a certain guarantee.

As for the fence, Chen Yang only left two openings.

One opening is the fire stair passage, and the other opening is for placing water pipes.

Water pipes run directly from the roof to waste water tanks in the ground.

This rainwater collection pipe is also equipped with a cover that can be opened and closed at any time, and the cover is usually closed to prevent foreign objects from entering.

At this point, the entire water tank is processed.

The last and the last, the only thing left is to fill in the pit.

Chen Yang turned back to the refuge and opened the bedroom door. Jiang Yanbing was sitting by the bed blowing on the air conditioner.

"Is it cool?"

Jiang Yanbing nodded: "Well, have you finished everything?"

Chen Yang opened the curtains, letting in the sunlight from outside, which was drawn by Jiang Yanbing himself.

Feeling full of respect, Chen Yang pointed to the direction of the water tank, and handed the shovel in his hand to Jiang Yanbing:

"Let's go, just fill in the hole just now."

The two came to the side of the water tank pit, and Jiang Yanbing looked at Nuo's big water tank, a little dazed.

"What is this?"

"Water tank." Without raising his head, Chen Yang began to concentrate on filling the hole.

Jiang Yanbing had doubts just now. When she prepared the pesticides just now, she used a kind of clear water.

It's not quantum water, she can feel it just by feeling.

Where did the water come from?

"Do we... have this much water?"

Chen Yang chuckled: "You don't understand this, it's for waste water!"

"Wastewater? What's the use of waste water?"

There were more question marks on Jiang Yanbing's face.

Even when she lived in the open air, she never drank waste water.

That thing is not for people to drink at all.

It's not a secret, Chen Yang didn't say a word, while filling the hole with Jiang Yanbing, he told her about the water.

Although Jiang Yanbing is an idiot in science and engineering, he is not a fool.

Although she doesn't understand the principle, she now understands one thing.

After the waste water passes through the filter, it can be turned into drinkable water!

What made Jiang Yanbing even more unbelievable was that Chen Yang said just now that much of the water in the taps before the end of the world came from domestic sewage or wastewater.

This was the first time she knew about it. She always thought that the water came from a freshwater lake, and at worst it was rainwater.

Thinking of the fact that the water I drank probably came from waste water, I still feel a little weird.

It's just the blame, Jiang Yanbing didn't think there was anything wrong.

It is the end of the world, and it is a great happiness to have pure water.

"In the future, we will use pure water for our daily life. As long as we don't waste water, we don't need to save water so much in the future. Anyway, the waste water here is endless."

Jiang Yanbing nodded:

"Then is there any waste water in this waste water tank now?"

Chen Yang shook his head.

Jiang Yanbing continued to ask:

"Do you want to fetch some waste water from other places?"

Chen Yang snapped his fingers: "You guessed it right. Then we have to fetch some waste water for filtering."

Chen Yang said "we" instead of "you", which made Jiang Yanbing feel a little strange.

It's a bit sweet, as if you just drank quantum water.

"It's just." Chen Yang exhaled, and looked directly at Jiang Yanbing:

"It's not easy to fill up this water tank. We don't have professional tools now, so we can only do it little by little. Let's get a little water first and then use it. After two days, I will go around to see if there is any means of transportation. Wastewater can be transported in large quantities from the outside.”
