Thank you for sharing your information with us, it has been very informative. I very much appreciate you responding to the comments viewers make, others just go silent. Keep it up, thanks a bunch. I just did a borehole with a machine in Pallisa at a depth of about 130 feet but the casing went down to around 120 feet. An electrical submersible pump is used. Is it normal for the water to be pumped for about 10 minutes than it dries up. We wait another 10 minutes or for the recharge. At this depth we installed 7 screened casings followed by the plain casings. All of 5 inches in diameter. Is this normal for the water to dry up just after around 10 minutes then wait for a recharge, or should it be continues flow for however big the aquifer is? Also normally how deep should one drill below the water table once the depth of the water table is known? This is the first borehole done with a machine before going out to help the poor in the villages near Pallisa. Many thanks again, I appreciate your work
Hello, Thank you for checking our demo video and writing to us. 120 feet seems shallow for a machine drilled well however it's possible to have good aquifers at that depth. It's not good and professional to pump and the well dries out, this will draw all the water from the springs and water will start coming with silt, after some time your well may get filled with silt up to the pump level, it's advisable to do pump testing (weisengineering.com/borehole-pump-testing-in-uganda/) before pump selection, of of the main reasons for carrying out pump testing is to determine well yield such that an appropriate pump can be selected. There is no specific depth someone should go below the water table (water strike), factors like type of rock, well diameter, casing method may be looked at, i think it wouldn't be more than 6 meters.
