The Process of drilling a borehole involves the following stages.
With the below documents at hand, one is now ready to drill a borehole. Drilling a borehole involves sinking a 8″ diameter hole to the recommended depth. The borehole is then installed with 6″ diameter casings to depth drilled and the annular between the borehole wall and the casings is filled with gravel packs. The borehole is then developed for about four hours depending on level of silt and backfill in the borehole.
