A drill worker investigating a site for a new sewerage system struck a main pipe, causing more than 7,000 cubic m of water to gush out - enough to fill three Olympic-size swimming pools.
It took eight hours for PUB engineers to isolate the main, and the contractor was billed for repairs totalling more than $122,000.
