In 1852, three years after London’s worst cholera outbreak and the consequent demand for cleaner, safer water, the East London Waterworks Company constructed the six Middlesex filter beds to remove impurities from the River Lea and provide the surrounding areas with water of improved quality. In later years the filter beds were augmented by another 19, seven of which are now the WaterWorks Nature Reserve (formerly Essex Filter Beds). In total, the site produced an average daily supply of 42.5 million gallons of water. In 1969, after over 100 years in operation, the Middlesex Filter Beds had become outdated and were replaced by the new Coppermills Water Treatment Works in Walthamstow. Thames Water became responsible for the beds in 1974, by which time nature had already taken over and wildlife had begun to colonise the abandoned site. Since 1988 the site has been leased to the Regional Park, which has since managed it as a wildlife reserve.
Each disused filter bed is managed to provide a variety of habitats for wildlife including open water, reed beds and wet woodland. The value of the site for wildlife is increased by the nearness of other open spaces such as Walthamstow Marsh, Hackney Marshes and the adjacent WaterWorks Nature Reserve.
BIRDS More than 60 different species have been recorded at the site including Snipe, Reed Warbler, Firecrest and Sparrowhawk.
OTHER VERTEBRATES The wetland areas are ideal for amphibians such as toads, frogs and newts, all of which breed here.
INVERTEBRATES A variety of damselflies and dragonflies are also common throughout the summer months.
