In 1850 North London saw a permanent Local Board of Health set up to combat the problem of sewer and persistent water contamination. This eventually resulted in the establishment of a sewage treatment works and pumping station, which remained in operation until the mid 1960’s. Recognised as a Site of Industrial Heritage Interest and Importance this Grade II Listed building is a unique reminder of the remarkable success of Victorian engineering and technology. The Pump House, now a working museum, offers members of the public first-hand experience of the engine in operation. The windows have now been opened up and fitted with protective screens that follow the lines of the arched windows. Selectaglaze provided a system of panels glazed with an anti-vandal polycarbonate sheet fixed to the outside of the window and finished in a dark green to match the window frame.
