It's often not the steam pipes leaking. The sewers are very humid and warmer than the air above. As the air convects up it hits the cold air and the humidity condenses. The same thing happens in lots of other cities when the weather is right. Maybe the steam pipes keeps the sewers warmer in places with steam but they should be well insulated in the end. |
