London Sewerage System

The London Sewerage System is a water infrastructure that services London, England. It was built during the 19th century, when the River Thames was an open sewer. Because the River Thames had become a public, unorganized sewerage, it posed a threat to people’s health. It was during those times when London was smelly and dirty. The filthy city also resulted to a cholera outbreak. Because of this condition, a proposal for a better sewerage system was suggested in 1856, but it did not prosper.  It was only in 1858 when the government realized the growing problem of the region. It was in this year when the construction of London Sewerage System took place.

It was the Chief Engineer of the Metropolitan Board of Works, civil engineer Joseph Bazalgette, the government commissioned to build the London Sewerage System. The design that the civil engineer created for the London Sewerage System diverted the pollution and waste to the Thames Estuary. The civil engineer designed six main interceptors which came out to be about 100 miles or 160 km in length. There were interceptors incorporated in the underground rivers of London, or the “London’s Lost Rivers”, and in the Thames Embankment. The Thames Embankment later resulted to new thoroughfares and city gardens.

With the natural aid from gravity, it allowed the system to flow eastwards. But, pumping stations had to be placed in some regions, such as Abbey Mills, Chelsea and Deptford to support a correct system flow. In the 20th century, major revisions had to be done in the London Sewerage System, to reduce the pollution it brought to the Thames Estuary and the North Sea. The sewerage system was not left behind as the region evolved and developed. Today, it is almost 100 times bigger to accommodate the increasing amount of pollution and waste expected from a big, populous city.
