   Chapter 357 Groundwater Replenishment (22)

   "There's no way out of this dust storm. The corn stalks are either blown off or withered, so they can't live." My father squatted on the ground and spread the long corn stalks out in front of the house, ready to be used as firewood when they were dry.

   Fuel is also precious in this day and age.

  After all, trees and other common plants have all gone extinct. Maybe the last piece of wood was thrown into the fire by a certain person for cooking some unknown number of years ago.

  The mother also had a sad look on her face, "This sandstorm has been forecasted in advance, and there is nothing to do about it..."

   "The corn stalk can't escape. It's blowing in a dust storm. What can you do?"

  My father was talking, he had already processed the corn stalks, turned around and went to store the water in various containers for airtight preservation, while Aqiu went to prepare meals with his mother.

   It is said to be a meal, but it is actually a bit of the latest dried earthworms, plus some well-preserved cornmeal and sun-dried corncobs.

   "Fortunately, the food has been distributed recently, otherwise the corn will suffer, and I don't know what to do next."

  In the gloomy and gloomy atmosphere, the family was about to start eating when they heard the sound of a machine coming from outside the door.

  My father put down the old rice bowl in his hand, and went to the door alertly. He didn't open the door until he made sure that the people outside were not bad people, not even for his family.

   Outside the door, there were excavators neatly lined up in a long line, followed by a group of people wearing hard hats, who seemed to be discussing something and kept pointing at the ground.

   These people, A Qiu's father knew, not the people who really knew them, but the clothes they were wearing. The signs on them were the same as those of the doctors who gave them free clinics some time ago.

  One of the doctors also said that his daughter's throat could be treated by surgery, and he also helped to fill in the name of the special patient care list.

  Thinking that these people should also be good people.

   "What are you doing?"

  Aqiu's father asked a young man standing outside who also wore a red hard hat.

   The other party glanced at him and smiled: "We are looking for a suitable wellhead."

   "Wellhead?"

  Aqiu's father lifted his feet, feeling that something was wrong: "There is no groundwater in our place for a long time. If you want to dig a well, you have to go to the city."

  The young man said: "We are going to drill a wellhead that has no water."

"what?"

  Aqiu's father couldn't understand what this was thinking at all. What use can a wellhead without water be used for?

  Why are there still people who specialize in drilling this stuff?

   seemed to see his confusion, the young man explained: "We don't want to pump water from the ground, on the contrary, we want to pour water into the ground and fill it back."

   "This way, the groundwater can be replenished, and it will be much more convenient for you to use water in the future. You can directly fetch water on the spot."

   Replenish groundwater?

  Aqiu's father understood.

   Isn't that right?

  There is no water in the well because the groundwater has been drained, so they can refill the groundwater by refilling the water from the wellhead?

But…

   "Where does the water come from?"

   The young man's smile suddenly became brighter. He grinned with white teeth and said, "Brother, if I said that the water was drawn from the Antarctic, would you believe it?"

  Aqiu's father pondered for a moment, stared at the young man in front of him, and asked very studiously, "Where is the South Pole?"

Uh…

  The young man was speechless for a moment.

  …

   Zheng Xu did not expect that the man in front of him, who looked only in his twenties or thirties, didn't even know about Antarctica, which surprised him.

   Suddenly, his eyes moved down, and he saw a little girl beside the man's legs. She seemed to have a familiar face. It seemed that it was the little girl who helped him and Captain Yin to guide them when they first came to this time and space.

   Zheng Xu raised his eyebrows, and didn't bother about Antarctica anymore, he reached out and touched the girl's head: "Brother, is this your daughter?"

   "Well, her name is Aqiu."

  A Qiu also stared at Zheng Xu closely at this time, and took the initiative to nod at him, obviously remembering him.

   "Then Ah Qiu went to school to study?"

  Aqiu's father shook his head: "I want her to go to school, but we haven't opened a school on our side yet, so it's too far for her to go to another city."

  Zheng Xu is not surprised, the renovation work in various places is fast and slow, which is normal.

   "It won't take long for your urban area. When we fill up the water for you, the school should be renovated. Maybe Ah Qiu will get a good score, and he will be a scholar in the future..."

  Aqiu's father touched his chin, but he was still eager to learn: "What is a scholar?"

   Zheng Xu: "…"

   A low-lying area dozens of kilometers away from Zhengxu.

   Zhang Tianyuan and Yuan Heguang are both here at this time.

   Now this place has changed from a desert to a construction site, and nearly a hundred excavators are working here.

  The methods of artificial recharge of groundwater are generally divided into two categories.

   One is the surface infiltration method, that is, the water that needs to be recharged is diverted to low-lying seepage depressions, ponds, sand pits, and specially excavated trenches, canals, and pools, so that water infiltrates through its bottom to replenish the submerged aquifer.

   One is the well irrigation method, which uses existing pumping wells or specially constructed water injection wells to recharge water into the ground, which is what Zheng Xu is doing.

   And what they practice here is naturally the first method.

   Now these excavators are digging seepage pools that are specially designed to allow water to seep back into the ground.

   There are at least hundreds of construction sites like this in China, all of which are prepared for water storage.

   This is also the most suitable method for interstellar space-time after research.

  Otherwise, if the water from the acquired time and space is introduced into the ground, it will be too wasteful for the present where desertification is serious.

   It is time-consuming and laborious to build a special sealed water channel.

   So the engineering team put their eyes on the ground.

  When the terrain and geological conditions are suitable, the subsurface aquifer can be directly used as a natural underground reservoir.

   In the wet season, when the surface water source is sufficient, the water can be stored in the voids of the aquifer to obtain quite good storage conditions.

   In addition, because groundwater moves slowly, evaporation and discharge are also limited. As long as it is properly allocated, it is not difficult to successfully recycle most of the artificially supplied water in the future.

  According to the current exploration and the geographical and hydrological data left before, the Mutual Rescue Association and domestic engineers have marked all the "underground reservoirs" nationwide.

In the Antarctica of the day after tomorrow, the crushed ice factory has been in operation for a long time, and a large number of ice cubes have been prepared. As long as the seepage pool here is dug, the ice cubes can be sent directly to let them melt naturally and seep into Ground…
