Why Power Flushing Matters in Southwark

Southwark's 19th-century sewer system is one of the oldest in London, built by Bazalgette in the 1860s. Victorian properties in Bermondsey frequently experience drain backing-up caused by the age and capacity limits of the original sewer infrastructure.

Housing stock: Victorian terraces in Bermondsey and Peckham, 1960s–70s council blocks near Elephant & Castle, and significant new-build towers on the South Bank.
