The London Sewerage System

The London Sewerage System is a network of underground pipes designed to carry waste and rainwater away from the city to treatment facilities. Established in the mid-19th century, it was largely influenced by sanitation crises that caused disease outbreaks. The system prevents pollution by ensuring that sewage is efficiently transported and treated before entering the Thames River. Major improvements, such as the construction of the Bazalgette sewers, have made it one of the largest and most efficient sewer systems in the world, playing a crucial role in maintaining public health and protecting the environment in London.
