A watery quarter lying beside Walthamstow Marshes on the southern banks of the River Lea reservoirs. Nowadays, most of Coppermills
is occupied by Thames Water’s filter beds and pumping stations, which replaced the Lea Bridge waterworks in 1972. A mill has existed here for many centuries. The present Coppermill building was erected two centuries
ago, and copper coins were minted here during the Napoleonic Wars. It was converted to a pumping station by the East London
Waterworks Company in the 1860s when the tower was added. Water from the New River arrives here after its journey south through
Hertfordshire and Coppermills is a major supplier to the London Ring Water Main.
The neighbouring residential area lies on the western edge of Walthamstow. At Coppermill primary school, on Edward Road, nearly
60 per cent of children come from minority ethnic backgrounds, mainly African-Caribbean and Pakistani. Over a third of pupils
have English as an additional language.
