New Youtube Video – Rotary Jetting Well Drilling

A new youtube video has been published on our youtube channel.

The video shows a custom made well drilling method called rotary jetting. It combines a rotating drill head with a water jet. If you are interested also have a look at the experimental setup of airlift drilling and the motorised airlift drilling setup.

You can watch the video below. Don’t forget to also have a look at the other videos at our channel

    Hi friends,
    Thank you very much for sharing your knowledge, it is very good information.

    I would like to know if you could provide me with an already manufactured rotary jetting swiffel? or do they sell them? …

    Best regards

    Hi, my name is GREAT DAVID, am from Nigeria. I appreciate your video and will love to do something like this in my place too. I want you to please help me with all detailed technicality involved in this, from the construction of the jetty using drilling machine. Please all that’s involve in the construction.
    Hope to hear from you soon.
    Thanks

    Have downloaded the specs for the swiffel drill.
    In the video you also had drill pipe with a few modifications and a clamp to hold pipe in place when adding/removing pipe. Do you have schematics for those components.

  7. Bu Gaui says:

    Dear Sir,

    I just wonder what is the diameter of the drill bit and what size of PVC pipe is suitable as your demonstration?

    Kind regards

    Bu

  8. Tony says:

    Anyway you could publish a video in how to build this?

    Hallo,
    Ik wil deze zomer in Kilangala, Tanzania een aantal waterbronnen boren voor een aantal boeren van het dorp. Dat doe ik vanuit mijn kleine stichting Water for Everyone uit Kollum (Friesland). Ik heb ooit eens een Baptist boorkop laten maken en zelf met driepoot, touw en 1 inch pijpen uitgeprobeerd maar dit viel nogal tegen (in onze klei hier). Fysiek heel zwaar werk. Ik zou liever een boring doen met een vuilwaterpomp zodat we mud vanuit het boorgat omhoog krijgen en via een bezink kuil het water weer kunnen rondpompen. De kop van de Baptist boor opstelling kan ik wel gebruiken en we willen een vuil water pomp aanschaffen voor deze toepassing maar ik ben benieuwd hoe ik het tussenstuk onder de boormachine kan fabriceren. Waar water in de draaiende booras gebracht wordt. Ik heb de tekeningen gedonload maar begrijp nog niet alles. Kan ik een keer langskomen voor advies en zien hoe ik dit kan maken? Ik heb evt wel een draaibank beschikbaar of is het onderdeel ergens te koop?
    Ik heb geprobeerd te bellen maar dat lukte niet. Ik kom graag een keer langs. Graag uw reactie.
    Alvast bedankt

    Hallo Leo,

    Bedankt voor jouw bericht.
    We hebben inmiddels contact met je opgenomen via de mail.
    Maar kort gezegd gebruiken we zelf het liefst de EMAS methode voor het handmatig boren van een put, de Rotarty jetting methode word pas echt interessant als je erg veel putten wilt gaan boren.
    Een langer antwoord staat in je mailbox.
    Mocht je verder nog vragen hebben dan kan je daar natuurlijk altijd op reageren.

    Hello. Thanks for the video about drilling a well with drill. It looks like most of the above are asking questions like I am wondering….if you could possibly (even using the same video), tell us the size pvc, the purpose for cutting all those slits on each side of pvc, etc? There was a lot that I don’t know enough about wells to know what you were doing or why. Please don’t take me wrong, the video helped but for people like myself, I would not know when to stop drilling, the differences in soils that you put on that board, etc. You may already have a more detailed video? If you know of another video link, that would work too. I know I have a deep well that’s about 75ft deep but pump is about 65ft deep, the water is first hit about 42ft deep (best I remember). It has the 6″ pipe though. Anyway, anything that would help me to understand everything better would be great! It looks simple and want to try it. Thanks again.

  12. Ricky says:

    Hello I was wondering the specs on and how to create the drill pipe and drill bit? Also how dose the drill pipe connect to the drill rig? Any info would be greatly appreciated. Thanks for your time

  13. admin says:

    Hello Ricky,

    Thank you for your question, the drill pipes are metal pipes connected with threaded couplings, we welded on some wings so we can tension the pipes with the wrench you see at 5:36.
    The drill bit is made from a bought drill bit with pdc inserts (A very hard material used for drilling) and is widened to the diameter of our well.
    We do not have technical drawings available for these parts, but if you have any more questions feel free to ask.
    We do have a drawing for the swiffel, you can find it under our water supply publication (here)

    If you are planning to drill just one well it might be a good idea to look at the baptist or emas method, these methods are easier to setup.

  14. Joey Lavarias says:

    I don’t have the means of fabricating the swivel component that require machining.
    I prefered to buy 1 if you would like to sell the swivel assembly only.
    Thanks,
    Joey

  15. miel says:

    Heb jullie net via het formulier bij ‘advies’ een mail gezonden over een project van ons.
    Benieuwd naar jullie antwoord.

    groet,

  16. Tony says:

    I think you can setup a bussiness by selling the little parts like the rotary swiffel ready made. People are interested in buying

  17. JL says:

    Very interesting video! Have you tested how deep you can drill using this method?
    I am considering diy-ing my own geothermal well, here in the Netherlands. This could definitely be a way to do so.
    If I succeed, I also want to make geothermal energy more available for others. Maybe we can cooperate in a certain way.

  18. Jelle says:

    Hi,

    What depth could be reached with this technique? I am interested in drilling my own geothermal well and this could be a feasible way of approach.

    Cheers

  19. Jay leija says:

    I’d be interested in buying a setup from you aswell. If you were to build a whole set up “ a complete package” I’d be willing to buy and pay for shipping.

  20. Ishola says:

    Good effort. Please could you provide information on
    1. The construction of the inlet water pipe into the power drill connection point to attached pipe so as to allow water to flow into the pipe.

    2. the power rating of the power drill

    3. the maximum depth of the pipe

    Thanks

  21. JEFFERY E. PROTIC says:

    I complement you for a wonderful job and your innovative techniques. I am going to try your system at a residence in order to take advantage of the shallow water table for geothermal in Florida

    Great video and great job

  22. Hans says:

    Hi,

    Wat een mooi en simpel concept. Zouden jullie contact met mij kunnen opnemen via de mail alsjeblieft?

    Alvast dank.

    Mvg Hans

    Hello, I’m currently living in Kenya in Nakuru county, in my area we have challenges of water , since I have been following you organization I requested for any help or guidance since you have all the equipment for drilling

  24. scott kotaska says:

    how can i get info on the construction of the drilling assembly mounted on the drill ….

    kindest regards…
    scott

  25. Hi,

    This is a great setup! Really great! Are you interested in coming to Malawi and train some women on how to drill these at preschools for our preschool project? We are training caregivers and develop model gardens so they become self sufficient. If yes, please reach out… If not, please reach out anyway 🙂
    Hiere is how we recycle plastic to produce oneway pump valves.

  26. Orlando Silva says:

    Hi,
    What kind of hand drill you need? What power? What maximum torque you need in the pipe, what kind of pipe? I think the torque of the hand drill should be less than the maximum torque of the pipe.

  27. admin says:

    Hello Orlando,
    Those are good questions, have you looked at our manual?
    https://www.wot.utwente.nl/publications/drawings_rotary_jetting_swiffel.pdf
    In the manual we mention two drills that we have had good results with:
    – Hitachi/Hikoki DS18DJL (cordless with 1.5Ah batteries)
    – Makita DF0300 (corded)

    The maximum torque of any steel pipe is easily more than the torque these drills can provide, so this shouldn’t be a problem.

  28. Kristoffer says:

    I’d like to purchase a setup from you as well. If you were to build a complete setup, I’d be willing to buy and pay for shipping. For well drilling, I also like to recommend on seeking a professional help.

  29. Jack Morton says:

    I am interested in using a similar setup to redrill a 50 year old deep (artesian) well that was unused for most of that time, and its output has greatly diminished. Well casing is either 2″ ID or possibly as small as 1 1/2″ ID. Do you think this method is feasible to restore output to something closer to what it must have been at the beginning. This is in Florida, USA. Shallow wells are routinely dug in sand & clay. Deeper wells may encounter calcium carbonate layers, but as this is an attempt to restore a well already professionally dug many years ago, that may not be a problem. Flow restriction may be due to mineral buildup inside the casing, or some other cause. Will be glad to get your thoughts.
    Like the others, I am not set up to fabricate all parts of your rig as shown in the video. Do you know a source for the various parts?
    Many thanks for putting the video together, and sharing it.
    Jack
