People define heritage in different ways, not based on which dictionary they use, but what their occupation is. The architectural consultant who planned and got executed the repair and renovation of our building possibly interpreted it as something that must be seen from the outside (what they call facade of the structure) as it was when the structure was created. Probably in order not to mar the beauty of the building in any way, he has put the drainage trap in plain view of the operation theaters, staff room, and corridors.
Probably the heritage, in his opinion, lies in what people can see from the outside rather than what the contents of the structure are in reality, both physical and traditional. I recall when one of them started leaking soon after we moved in, and the whole corridor was flooded by the waterfall - what could be termed 'heritage waterfall'. It was fixed somehow - I hope not by a bypass.
