We have a borewell drilled in AECS Layout, Bangalore with depth of 1068 ft. The diameter being 6.5". When we did a camera testing we could see water stored from 510 ft. The water sources were found at the following depth
1) 350 ft
2) 525 ft
3) 530 ft
4) 705 ft
At 710 ft we could see that borewell was blocked. The camera testing guy said that the blockage seems to be due to a loose boulder and there ais some silt accumulation. I have loaded the videos at the following link. Can someone let me know what can be done to take out the block.
