Many spoon drains and culverts in the grass at Changi, add to that rain and the ground may have been too soft for fire engines. In any event, a fire engine over tarmac is likely to be faster than one over the grass.
So much rubbish posted here, sadly some from pilots. Fuel dump with a fuel leak?
Do you think it better to land over-weight with a fuel leak or consider that it's not a good idea to dump with one?
