London Museum of Water and Steam

The London Museum of Water and Steam stands on the site of the old Kew Bridge Pumping Station in Brentford, beside the River Thames in West London. Founded in 1975 as the Kew Bridge Steam Museum, it was rebranded in 2014 after a major redevelopment. The museum centres on a collection of stationary steam engines used for water pumping between 1820 and 1910. It holds the world’s largest collection of Cornish cycle beam engines, including the Grand Junction 90 inch engine, once the largest working beam engine in the world. The site is also an anchor point on the European Route of Industrial Heritage. The museum’s engines once supplied drinking water to much of West London, from Paddington to Ealing. The Grand Junction Waterworks Company opened the pumping station in 1838 after closing an earlier site at Chelsea due to poor water quality. By the mid-20th century the station used six steam engines and four diesel pumps before electric pumps took over in 1944. The Metropolitan Water Board preserved the steam engines, and volunteers formed the Kew Bridge Engines Trust in 1974 to restore them. The museum has received awards from the American Society of Mechanical Engineers and Britain’s Institute of Mechanical Engineers for its restorations. Visitors find a mix of working steam engines, displays and artefacts that tell London’s water supply story from Roman times to today. The museum runs monthly ‘Steam Ups’ when engines are fired up for public viewing. The Great Engine House, home to the Grand Junction 90 inch and 100 inch engines, is being restored with a £2.6 million grant. The site also includes an education programme linked to the National Curriculum and an archive of steam and water-related items. The museum remains a reminder of London’s industrial past and a working testament to steam power’s role in public health.
