Toilets have been around for a long time. They have been discovered in Scotland from as far back as 3100-2500 BCE. The first flush toilet was not invented until 1775 and was not introduced to the masses until 1851. The Clean Air Act, to clean up our waterways was not passed until 1972. As of 2014 2.5 billion people do not have access to flushing toilets and sanitary sewers. It is the invention of sanitary sewers that have stopped epidemics and the rapid spread of diseases such as the Cholera Epidemic in London in 1831. As a funny note Melbourne Australia was called “Smelbourne.”
