- EMAS drilling is a completely manual DIY drilling method for making your own borehole. You can produce your personal drillset without the need for complex parts or tools. Relatively deep wells can be made.
For more information on construction and use of the drillset have a look at the videos by EMAS: / emasbolivia

I'm blown away by the efficiency of this system. It's absolutely remarkable and these techniques for drilling Wells need to be preserved and spread far and wide. Water is a huge challenge for human beings and any cost-effective method that doesn't require electricity and can be done almost anywhere is super valuable to human beings.
I’m blown away that after 50,000 yrs these people don’t know how to get water out of the ground all by themselves.
@@robertmccarthy1256 I'm pretty sure that's exactly what you're watching in the video. Is them getting water out of the ground by themselves. I don't at all understand your comment. Quite frankly it's bizarre and makes no sense. Probably the mind of a radical leftist lgbtq democracy supporter
@@robertmccarthy1256 50,000 years ago people lived near a river, lake or spring. With large populations demanding water away from a surface source then artesian water is the only option and it can be hard to attain, especially if it is 100m down.

@@robertmccarthy1256 50,000 years ago? No way you aren’t trolling or you are 14 zzz
I hand dug a well at my new shop 3 years ago 40 ft deep and I put a 6 in casing with 1 3/4 pipe in side of it I filled with 57 stone after my 6 in pipe and red clay at the top to seal it it took me 3 days by myself and there was about 10 on lookers watching me I know they were talking junk about how crazy I was till I hooked my pump up and sprayed the water hose in a Rainbow style with 60PSI on the pump for an hour just to show I really hit water And a lot !! Thanks for the video I'm in north Carolina red clay county and let me tell u got to be young at hear its really hard work just my 2 cent !! By myself I might add !!
Ur a liar
I guessing you left out some details or I'm calling bullshit! A 6" diameter hole in the ground 40 feet filled with water; that water would weigh 480 pounds!
How were you able to push that kind of weight to the surface by hand?
Even a smaller column of water as used in the video is the big limiting factor of a well 300 feet as they suggest is possible.
That's water weight. A thick mud slurry like they suggest weighs even more with every inch in diameter or depth.
Think of your 6" pipe as a plastic liter bottle about a foot tall. Now lift that bottle to stack another bottle under it. Lift those two to stack a 3rd under . Then lift all three to stack the 4th. Continue until your lifting a stack of 40 to slide the 41st bottle below and you will understand the gravity of the situation. Literally!
I'm not saying it's impossible but it's impractical with the limits of the tools shown here.
@@tenlittleindians You're not lifting the water, though - you're inputting water at the bottom of the water column to "flush" out debris. I agree that there is a limit on how deep you can go based off the pressure required to input additional water at the bottom of the column; but, if you were to replace the water hose here with a power washer, that'd get you considerably more distance. You might want to understand basic physics before spouting off, because there is a huge difference between your analogy of "lifting water", and the actual issue here of "back pressure" on a water output, at the bottom of a water column.
@@jcpt928 To inject it in the bottom requires the same force as lifting the column of water! Were you unaware how it's calculated? And using a high pressure pump ain't exactly "digging it by hand" anymore.
Your "flushing it out" story doesn't hold water. (See what I did there? It's known as a play on words)
How are you going to "simply" flush it out? You either need to lift all the casing to create an opening at the bottom or your back to pumping water down the casing which requires pushing that water somewhere once the casing is full. (Back out the top under the full pressure that I previously calculated)
I suggest you visit a local grade school and see if one of the nice teachers can take some time away from a toddler to help you brush up on your limited capacity for simple basic math.
@@tenlittleindians You're completely dismissing the size, surface area, etc. of the casing, the digging head, the hole itself, etc.
You clearly aren't paying attention. Water isn't a solid.
Thank you. I wish I had three friends. Only a real friend would help drill a well. May God bless you and yours as you bring this knoledge to the world.
I was thinking the same! Maybe people watching has family that’s still alive and able. And has land that they can call their own
amazing comment.
Decades ago, my well driller showed up with his huge truck-mounted drill rig. He reminded me of the price per foot for dirt (cheaper), and the price per foot for rock (more expensive). His drill bit was placed on the ground, and it made a ONE-HALF TURN and clunked into bedrock. The driller looked at me and said, "I guess it's rock all the way down." 302 feet of solid rock, but 10 gallons per minute total flow. So a nice reliable well and the pump is 30 years old and never been out yet.
PS. U of Twente, I like your on-line SDR. Very very nice, and much appreciated.
Congratulations!! This video underscores the need to utilize the readily available resources; in this case, the Human Power and Wisdom. What a Marvel!!
Yup!!!!!! Is thier an 0 anywhere? Proabably not! Have people worked to hard for far to long! Probably have! Anything else? Have the best day possible
Thank you very much, I'm watching from Papua New Guinea.
This is quite a fantastic video. Very inspirational.
One could drill his one well following your instructions.
Thank you and greetings from Portugal.
Excellent video! The ball valve cylinder tech is actually quite old and has been used in water and petroleum wells for 150+ yrs here in the US. It works very well!
Thousands of years in China IIRC,
Thank you for posting this remarkable video! It sure gives do-it-yourselfers things to keep in mind!
Really appreciate the detail and information presented here. Thank you kindly!
Very cool stuff! Thanks for sharing. Glad to learn this can be done by hand, and i bet this could help lots of people in developing countries.
Very interesting seeing another method for drilling a water well.
I would love to drop off my work truck to these guys. The tools and materials would make these guys happy af
AMAZING process, very clever. I cant imagine how many times has been perfected and optimized to reach this point.
Very well done video. Instruction was excellent.
So simple, yet brilliant allowing People to have clean, safe Water 👍👍👍👍👍👍👍
I'd have to say that was mighty educational
Terrific video. Thanks so much for sharing! ☺️🙏👍✌️🇬🇧
Amazing work gentlemen. God bless you.
Very nice explanation. Keep up the good work
What a cool video & practical from UK 🇬🇧 thank you.
Great video, these men worked very hard
This is a great tutorial for understanding the basics. Can upload videos more often? I love watching these kinds of videos?
God bless you sir, thanks a lot for sharing your good experience.
Amazing...kudos to all involved.
Amazing video, thank you so much, Engineers Without Boarders SDSU chapter will be building a well in Uganda, this was a very well done video :) it makes me excited to take on this project :)
great job buddy. you're the man. you're the man. all thumbs up for you
This was a very nice documentry.
Very clever, well done 👍
Amazing! We must not forget what we already know!
Awesome video Great work !
Awesome video!
Thank you..God bless..❤🙏..Papua New Guinea
I would love you to try it here in PA...we grow all kinds of rocks.
Good video, though.
Excellent work!
Thks, brilliant engineering (I envy them in a very good-way).
Clever Brilliant simplicity
Wow super job. Smart man seen in Toronto ontatio Canada
Well done!
Basically a drilling rig scaled-down. Cool
these men are amazing at what they did....i am very impressed and wow'd by the sheer determination to win.
well done
Well Done 😂
Clever ;)
Truly amazing! 👍 I was already ameze with DIY drilling well with power drill, but this is more crazy. 👍😃
One mark of a real engineer is the ability to use the materials, budgets and capabilities at hand
Wow Thank you so so so very much!
Nice use of simple technology. I do find it a conundrum: I need to drill a water well. I need water to drill my well.
Theres water on earth just need to travel to get it. Some further than others
Amazing coach, very usefull technique
You should mention that it will not drill through gravel larger than the inlet, it does not reach a high velocity that would overcome slip velocity. The pressure of the mud caused by the process can stop up the aquifer. There are other problems as well, but the process has been used in Bangladesh (without the pump) to drill as deep as 1000 feet and is more than 1000 years old. When drilling without the pump the process is called sludging in most of the world.
Hi, you are correct, this is a sludging method. Also the pressurised drilling fluid can indeed clog up the aquifer, this is exactly the reason why we need to thoroughly develop the well. About the gravel: the emas drill set will not lift up gravel. However, because of the shape of the drill head it is sometimes possible that gravel is pressed into walls of the borehole such that the drilling can continue.
@@WOT_utwente It is unlikely that the drill will force gravel into a wall of gravel. It is more likely that the bit will bypass the gravel and lock up the drill stem or keep the casing and screen from going full depth.. It is impossible to clear up a well that you cannot inspect for sieve size or for cake. Even using a mechanical rig, the aquifer can be stopped up several feet belong the centerline of the borehole. The direct circulation process can force thixotropic mud into course materials. Thixotropic muds are liquid when in motion and set to a solid when motionless. The small diameter diameter you are using is not capable the high velocity needed to properly release the thixotropic mud.
impossible to drill 1000 feet=333 metres.
Someone owns a drilling business?????????????
That’s amazing!
I live in pennsylvania, and it's solid rock
By the end of this video, I was telling myself "Well done".
A well is a deep subject.
Very good, thanks.
Excellent work, thank you!
And, have you considered filling the pipe with 1/3rd water? It would create a water-hammer effect, as the water bounces it transfers a greater force *per second* and the shock of that impact could help with soft rock...
Well you would have to install a valve just behind the drill head that can be opened from the top ... with say a pull string .
But the drill pipe is full of the mud slurry being pumped down to bring up sand and other material outside the pipe. Which I doubt it could lift rock chunks .
I like it. I am Ethiopian. I have seen a lot about how the pump works, but I don't see a simple procedure without you please show me. I hope you get back to me soon
Hi are you interested in the pump made from PVC pipes shown at the end? We made a video about this: th-cam.com/video/0DhFgb9IX4o/w-d-xo.html
@@WOT_utwente how can I contact you, see if you can sell me one those drill machine?
Hi there, could you please post a link to the video where you make the pump (Amos pump?), I tried looking for it but can't find it.
This is really amazing, unfortunately there's hard rock where I am so this wouldn't work. But I liked the pump and would like to make one.
I like this for its simplicity and low cost.
Impressive!
Thank you! 🙏♥️
Perfect !
Well done
I like this one a lot 👍👍👍👍
I just read your channel desc
👍👍👍 (x3 thumbs up)
magnifique !!merci du partage
The marble valve can be used in the making of ram pump too, ideal for villagers who live near a source of running water eg. small streams.
wow thank you!
good vdo, very educational.
I driller through 2’ of coral which is soft. It still wasn’t easy. I made a drill bit and used a big impact to turn it.
Totally would not do this but, it's super cool! :O
If the materials include rocks, your method cannot tell if the rocks are gravel or basement rock. You can use a reverse flow rig to have a better chance of drilling through gravel. With reverse flow we have drilled up gravel as large as 7 inches by 11 inches through a 8 inch drill stem.
Hi, thank you for your reply. Reverse flow drilling is indeed also a very interesting method, especially to lift up gravel.
Magnifique !
Goed gedaan !
How deep can it go in rock.
What kind of drill is needed?
Thank you for the great video
so clever
Do you think you could use this system to make a hole for a closed loop geothermal cooling system?
Looks like a lot of work. I’ll stay connected to the local water supply.
The ground where I am is mostly sand, I wonder if this method will work here...
People have been digging wells by hand for 1000’s of years without electricity. It isn’t that nobody can do it or that this is any great achievement. The great achievement is that we don’t have to do it like this anymore.
Not all of us.
ingenious
what do they call that little shovel. I want one! Great video!
thx mate
50 years ago I saw a well drilled in similar fashion but they used an old auto with the rear end jacked and a windless type hub secured to a rear wheel. A few wraps of the rope around it a a man could lift the entire drill stem with one hand! Though you'd like to know?
any water currnet /flow in wather underground? to use it as electricity generaton...
I would like you to try this in TN
this is wat i Look for.. the non -western- countries have the best easy tech as they have not become so dependent on company Consumerism ideals " you have to buy the new stuff, all the time"
i've only saw the marble and pipe. knowing how it goes and im already gunna hit that like
(find alot of god info from Africa and rural Indonesia)
I love the pump design, and the use of marbles as your check valves. Basically a very durable design
I think you are wonderfull, be blessed.
Where are you at? It looks beautiful.
This is exactly how old cable tool oil rigs drilled oil wells. They were much bigger and they went down over 300 feet but it was the same idea.
not quite.
But there are two issues.
1st cable drilling was used for water wells before long before oil.
2nd
a cable drill will go through anything.
it breaks up the ground / rock under it into tiny pieces.
its does this in very small section before needing to be " clutched" . or bailed out.
See below for a description of a clutch.
The small section are like 2 to 6 inches.
So you drill with the cable drill. ( a few inches)
Then pull the drill out.
Put the clutch in to bail out the bore hole.
Pull out the clutch. which is full of degree.
it will require a few times of clutching.
Then drill another few inches with the cable drill.
It is a long process. Taking weeks to drill. ... I suppose in some cases months even.
a cable drill will drill any distance. As long as you have the length of cable.
CLUTCH
A clutch is a small pipe that allows the slug, ( water and debree) to collect in. That is attached to a cable
Something like a bucket.
There is always water in the hole to mix the dirt / rock dust that the drill is breaking up.
There is no rotary action in the drilling.
it's simply a smashing action the cable drill is doing.
the up and down motion is breaking the ground under the drill. And mixing the debree with the water.
... My problem is I havent figured out how to make a clutch. I'm probably over thinking it.
Cable drills were still being used in water drilling in the Early 1980s.
However rotary drills were more common
The well driller in the early 80s I seen using a cable drill rig. Was a old timer
There is an old rig. on a guess 1940s truck. About 50 miles from me. That is just sitting.
I've been trying to buy it for a couple years. But can't get a hold of the owner.
I'm hoping it has a clutch with it. The truck is inside a fence.
OTTIMO LAVORO 👍
can you drill through shale?
Here in erbil/iraq in my area we dug 406 meters and still low amounts of water was found, so it depends on the area
Look at your sea level elevation and look for the highest water table in the area. That should help.
does this work in ROCKy desert area's?
Where is hand drill made/available for sale?
I does the same business here in Uganda.
Where in Kenya is this ....I just saw the hand bracelet
Come and try that in my rocky area.
So I need water to drill the well?
I made a marble check valve water pump in 1982. I invented it
That's great so long as you don't hit large rocks or gravel.
Good
