The source of the sinkhole that popped on Brigade Road on Thursday remains unclear. Both the BMRCL and the BWSSB say they are not at fault.
The mystery will remain unsolved for some time as metro authorities say a thorough investigation may not be possible.
A senior BMRCL official said the only way to find out the source of water leakage that loosened the soil and created the sinkhole was to dig a trench by closing the road. “It’s simply not possible,” he told DH.
Checking the alignment of water pipelines and power cables that run underground is not possible either. “The (underground) cable detector method is not very accurate,” he explained.
