Tutorial manual borehole drilling, SHIPO method 

Thanks a lot. Allow me to forward your compliment to Collins Msusonda (www.linkedin.com/in/collinsmusonda) who is working on an other animation (for Muzuzu) drilling at this moment. By the way, there are free manuals at www.jacana.help/resources/water

Thanks Moses Saranta, did you also see the even more easy methode: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-54MFysIzQ20.html ?

Thanks

You are welcome, there are more ways of drilling boreholes manually. SHIPO drilling combines a few technologies in order to be able to work is most types of soil structures. If you are interested in other methodes have a look at www.jacana.help/resources/water

Thanks, there are also other types of manual drilling have a look at www.jacana.help/resources/water

You are welcome sir. Did you also download the manual for making the drilling equipment and the manual for drilling at www.jacana.help/resources ?

@@JacanaHelp yes brother. Pakita ko sa welder. Thank you so much.

Thanks, it's hard work though. You need men like machines ; )

Gracias

Thanks Raul

Yes, Braith. Your suggestions are very welcome. More videos and manuals on affordable water supply are at jacana.help/resources.

Hello Braith Miller, If you have suggestions, please let me know. Thanks

@@JacanaHelp I will. Better to review your information to do it better. Some woud be improvements. The mortar-cement seal was the only one that could potentially cause problems the way I observed and heard the description. Assuming that bentonite clay may be unavailable or expensive local dried heavy clay chips should go down prior to prevent cement-sand from actually potentially ruining the well. Bentonite from the gravel pack to the soil grade is perfectly acceptable. Various codes in some places require mortar-bentonite seals honestly not better so if it costs more don't do it. Most drilling methods need to be modified for each local conditions. I have an interest in helping further.

@@braithmiller Thanks, Good suggestion. I never heard about sand/cement running down into the gravel pack that far. But it still makes sense. In Zambia WARMA is the groundwater authority overseeing our work. Thanks for the input.

@@JacanaHelp It is a risk I would not take without at least 20+ kilo of bentonite or local heavy clay chips settled on the top of the gravel pack first. You may by process get a natural clay barrier on the gravel pack. Regardless compliance with local rules. They will be interesting to know. They vary here, some not making sense.

In total it is about 1000 euro.

Thanks

Hello Eka Yuni Putra, can you confirm that the translation from Indonesian of your comment is "Very very good, very useful, God willing, Thank you" ?

If so, Thank you very much...

Iya, sangat bermanfaat Terimakasih

Two options: 1 If you know how to weld, you can learn to make them yourself at www.jacana.help/resources/water . 2 Or you order them from one of the welders we trained for example in Zambia, Tanzania, Malawi, Mozambique, Kenya or Ethiopia. Let me know what works best for you.

I think you can: Cleaning means loosing the dirt particles in the slots of the casing (for example with Swabbing) and as quickly as possible pump all of that dirt out and don't stop until water is clear. For swabbing you can use a piece of rubber that is almost the size of the casing (internal diameter) and under that rubber you make a stronger piece of plastic, a bit smaller than the rubber. Attach both to a strong enough pipe push it down slowly to the very bottom and pull it up fast to suck the dirt out of the slots. this way you wash the full length of the filter-screen (place where the casing has slots). After that quickly pump out the dirt with a pump that can handle dirty water. Don't allow the dirt to settle in the bottom of your borehole.

Another thing to do could be to place the pump at a different spot in the casing. Place it at a spot where there are no slots in the casing.

Let us know how this works out for you. Thanks and good luck.

In Africa people have time and are strong but money . . .

The machine will charge a lot of money, so it's better to do it yourself if you get the tools and time. The community will do the job together without any cost.

Rural Africa does not have money but it has plenty of time. the time needed depends a lot of the soil structure. An affordable electrical survey HEP and VES helps to determine the best location and drilling technology to use. More on that, see: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3QHpT1xYuss.html. There are manuals how to make and use the equipment at www.jacana.help/resources/water Now to answer your question: On average a drilling a borehole to 24m costs about a week.

Today a team reached 52 meter. But it very much depends on the type of soil. This method can break some rocks but not massive rocks. at www.jacana.help/mwater you can find a map of what is drilled with this method in Zambia. There are also teams in Tanzania, Malawi, Mozambique, Kenya and Ethiopia using this method.

Teams are cutting through pure rock layers if they are not too thick. Of cause the challenge is that you don't know how thick the layer is. So they often try for half a day or even a day making little progress hoping to shoot through.

What helps a lot is to do Vectical Electrical Sounding measurements to determine the best place to drill. The equipment can be locally made and use, manuals are at www.jacana.help/resources (short video on VES: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3QHpT1xYuss.html). We -for example- are in a place in Zambia that is "limited suitable for manual drilling" other manual drilling techniques fail easily. But when we combine VES measurements with SHIPO-drilling, the drilling success rate is above 90%.

Not sure about Kenya, we drilled in 2012 or so a few boreholes in Illeret above Marasbiet but there were no funds to train drillers.

You can ask www.smartcentregroup.com they coordinate this.
