DIY round well digging

It has nothing to do with the wood stove and chimney, but I dug a well a long time ago.

I would like to start with the story of why I bothered to dig the well.

In Sanda City, Hyogo Prefecture, where I live, the entire mountainous area has been designated as an urbanization control area.

Do you know the urbanization control area?

Even if I talk about this urbanization control area, I'm surprised that many people don't know anything else.

This urbanization control area is a quirk and almost completely shuts out newcomers who want to live in the countryside.

However, there are talks of closing the school because the number of students is less than 100.

The government has taken measures to prevent the declining birthrate, but the population of this area will not increase unless the urbanization control zone regulations are abolished.

This Sanda City is convenient because it is located about 50 minutes by JR from Osaka Station.

About 20 years ago, it developed as a bedroom town in Osaka, boasting the highest population growth rate in Japan.

Of course, there is no talk of closing schools in New Town, which still has a large population.

However, the problem lies in the mountainous area of ​​Sanda City, which has been designated as an urbanization control area.

This urbanization control area is a doughnut-shaped area around urban areas nationwide under the pretext of protecting the surrounding areas from overdevelopment.

As for the regulations, ordinary people cannot build new houses in urbanization control areas.

Exceptions include reconstruction of existing houses, branch houses of farmers, small shops that improve the convenience of the surrounding area, and public buildings.

Of course, regulations have a positive side as well.

There are still many thatched houses in the surrounding area, and the old-fashioned rural scenery remains, so you can relax.

If there were no regulation, modern houses would have been lined up without remaining.

It is very calming to see such an area like the original landscape of Japan preserved after passing through the new town.

However, on the other hand, the hurdles are very high for those who want to move to this area.

First of all, there is no choice but to buy an old house and renovate or rebuild it.

Even if there are vacant houses, there are only a few houses that are put up for sale.

In such a situation, it does not lead to solving the school closing problem at all.

Also, this is another problem, but the number of buses in the area has been reduced and it is becoming difficult to live.

Personally, I have a car, so I only take the bus once every few years, so I think a different approach is needed to solve this problem.

Anyway, because it is such an area, the environment is good and the comfort of living is the best.

By the way, I didn't originally live in the area I'm in now, but I'm going to be a migrant.

So I'm an oddball who relocated an old folk house from scratch to an existing residential land and started living there.

Sorry for the long introduction, but the reason we dug wells is because they are expensive!

If you ask how expensive it is, you will need 1,600,000 yen for the water supply work to the meter box.

In addition, the subscription fee will be 100,000 yen for a 13 mm aperture, or 300,000 yen for a 20 mm aperture, for a total of 1.7 million yen.

From there, the cost to bring it to your house is separate, so it will cost more.

How about you, do you want to pay?

Of course I couldn't pay at the time.

I still can't pay, so I'm using a well.

Consider them and dig a well! It became.

As for the excavation method, I dug easily with a backhoe to the depth of the first 1m.

Next, attach a scoop to the end of a small breaker to soften the soil, then put the soil in a bucket and winch it out.

It was really easy at first!

At this time, I also go up and down with the winch every time with the bucket.

Looking back on it now, I can't really rely on it, but I had to winch up and down this homemade wooden stand, and then go up and down with two buckets of soil, and then go down to the ground and repeat.

I always felt hot when I went up to the ground.

Water was dripping from the stratum around 3m, and it was always flooded.

Therefore, the water was pumped all the time.

We proceeded while enclosing the dug part with a wooden frame so that it would not collapse and die.

Burying alive is scary after all...

Still, if you work all day, would you have progressed about 60 centimeters?

It may or may not have gone further.

I had a hard time lifting it, especially when a large stone came out.

Finally, a round well with a depth of 6 m was dug.

I wanted to dig about 10m in the plan, but after all I hit the bedrock and did not proceed.

I tried digging in the well for a day with a large jackhammer connected to a concrete rock drilling compressor with an air hose, but it didn't advance even 15 centimeters in a day.

It was a very hard and bluish rock.

After using a jackhammer in the well for a day, I was physically and mentally exhausted.

My hands were numb and my ears were filled with the sound of bouncing.

Even so, my feet were filled with water gushing out of the ground, and it was so flooded that I couldn't work without pumping the water out all the time. .

In the end, I gave up digging, but I thought that there was beautiful water flowing under this bedrock, so I did my best.

After that, all the wooden frames were removed, and a concrete hume pipe was hung from above with a unique unit.

A hole was drilled around the bottom Hume tube through which water flowed into the well.

Then I put more and more gravel between the Hume pipe and the soil and made a frame on top with concrete.

The well is covered, the well pump is installed, and the faucet to the house is installed.

I remember that it took two months from start to finish.
