Third time a charm?

After two failed borehole attempts, today drilling begins on a new hole. Unfortunately after 200 metres of drilling we still had not struck water. The hole was abandoned and it was decided to try and repair the third hole which had collapsed since we knew it was yielding a reasonable amount of water. All the old PVC casings and gravel packs had to be drilled out to a depth of 120 metres. In addition to that 50 metres of steel casing was placed into the hole from the surface down into the solid granite, to seal off the clay layers that had collapsed previously. Fortunately the hole was successfully repaired and we were able to commence pump testing.

Pump yield testing indicates a sustainable yield of approximately 3KL per hour.
