Water is one of the few industries to which much of this applies. We all have to use clean water, we all want our dirty water safely removed and we have absolutely no choice about where we buy that from. There is just one supplier in each area of the country. They are 100 per cent guaranteed to have our custom however bad the service. So, it takes some doing to start up a water company with no inherited debts and mismanage it so horribly that it is taken to the verge of bankruptcy.
Eventually the situation became so bad that those using our rivers and seas for recreation began to find themselves swimming in sewage or trying to fish in rivers with little water flowing and horrible unnatural scum on the surface. Wonderful natural lakes like Windemere have been subject to massive algal blooms because of the amount of waste products dispensed into them.
