Re: Low Cost Drilling

Re: Low Cost Drilling

@ Ede, Regarding borehole developement with an AFRI casing pump; this is the same as with any other borehole casing, so best is airlift with a hose and compressor, 10 to 15 bar. Due to the smaller diameter of the AFRI PVC casing (70/80 inner/outer) this is even more effective compared with a large d...

Re: Low Cost Drilling

Further on the low cost drilling, let's not forget the good old cable tool low-cost drilling is not a modern issue, and has been done for over 200 years.

Re: Low Cost Drilling

Dear Ivo, Good to see your pictures. I like the robust outlook and the bailing methode also works fine, if time is not crucial and its not granite or the like you drill in. Personally, i believe more in your approach of a very strong equipment and not so much in the light constructed equipment that ...

Re: 44 Different Sample Designs Uploaded

DES-Latrine info Its all very fine, nice designs, but i think we do miss the point. One of the major issues in latrines, is the problem of "what to do with the waste...", especially in peri-urban, dense populated areas. A generally overlooked solution, is provided by the DES latrine system...

Re: Low Cost Drilling
