Drilling well for lowland location
For the manufacture of wells in the lowlands with a depth of 90 -120 meters in fact was able to release enough water abundant. However, it should be noted that at a depth of 50 -60 meters soil structure is still muddy then do the drilling back to obtain a layer of soil that is not muddy, but sandy, rocky or hard rock soil.
To ward off recharge from a muddy surface water source use a casing pipe on the wellbore with the goal of water at the bottom going through the pipe so that the water will remain clean despite passing through a muddy layer of soil. Water that is clean and suitable for use as consumption water.
