The TV coverage showed an enormous pipe that was going to be used to replace the burst pipe. That size of pipe would pump out a huge amount of water, overwhelming man-made and natural drainage. If you think about the damage that a minor (by comparison) domestic water leak causes, then the damage to property and stock is very large indeed. Stock can be replaced quickly. The basements and rooms that are used to keep the stock will take weeks if not months to dry out, wiring will be sodden and may well need to be replaced. Plaster will need replacing, but only after the walls have dried out, older buildings may have had walls undermined or even foundations washed out. So all in all, a bloody disaster.
