Hi
We live on the side of a hill which is 540m high. We live at 280m with about 2km (as the crow flies) of catchment between us and the peak.
We just drilled a well down to 40m, and had a geophysical examination done. Basically there is a layer of dirt and rocks and clay down till 19 metres, then 6 metres of rocks with cracks in them, and then after that very hard compacted clay until 38 metres, then 2 metres of rocks with cracks again.
The geo said that we should get a decent amount of water from the 19-25metre level as the water cannot penetrate the clay layer and should flow there. So the well driller put the perforated pipe between 19m and 25m and ran normal pipes down to 40m (for storage).
But the water is only flowing at about 6L per day.
One idea was that all the clay from the drilling process has leached back and blocked the outer side of the pipe.
Our neighbour has a similar well and said she had no water in the first 3 weeks and then after 3 weeks it started flowing very strongly.
Does anyone have any experience with this kind of well and what can be done to get the water flowing.
It was suggested to fill the well hole up with water and keep it full for a few days as this may clean it out.
Any ideas?
Thanks
Matt
