The making of the sewer drain

After investigating the Great Sink I am going to further research the modernisation of the under ground sewer system of  London. I am going to the year of 1866. This is the year the first and only Metropolitan board of works was created, where one Joseph Bazalgette was elected chief engineer. It is the mid-19th century London is still suffering from recurring outbursts of cholera. It is thought that this disease was air bound but is was not. The hot summer of 1858 was what caused 'The Great Sink', this together with the frequent occurrence of the disease cholera, gave impetus to legislation enabling the metropolitan board to begin work on sewers and street improvements. By 1866 most of London will connected to a sewer network devised by Joseph Bazalgette. The flow of putrid waste water from old sewers and underground rivers was intercepted, and diverted along new, low-level sewers, built behind embankments on the river front and taken to new treatment works. This great sewer system has dramatically improved the scene of London, as I walk threw the streets that I had not long ago wandered it has improved immensely, it is so much cleaner, the putrid smell of human waste has withdrawn, the deep ruts in the rode have now been covered up with bricks, there are no Dong hills to be seen and over all the faces that I pass are happier and brighter.
