why you work for PUB?
did you saw the picture of the size of the drain and the depth
of the flood?
Its one aspect to says that small secondary drain got
clogged....its another to say the main artery of drain got clog by
leaves....there is such a thing call overflow to the main
artery....
Please use your imagination and not just read......Walk to the
underground Drain Take a measurement of the drain...Do some maths
on rate of flow vs capacity of Water it can hold....
remember the flood was between 1 to 2 ft depth respectively in
various part.
He will tell you its dangerous to walk in a storm
drain.
