The earthen embankment is 17 metres (56 ft) high and the five sections total 953 m (3,127 ft) in length. It was constructed of local clay; a masonry overflow weir protects the reservoir from overtopping. Beneath it lay the trapezoidal Longdendale aqueduct that followed the contour to take water from the reservoirs to the Godley reservoir. Until the 1960s, water was treated by passing it through straining frames at Godley.
In the 1960s, a more sophisticated system of treatment was employed. Treatment plants were built at Arnfield and Godley. At Arnfield, lime, ferric sulphate and
Also in the 1960s, part of the Longdendale aqueduct was replaced with 1,200 mm (47 in) diameter pipes. In 1990, the Hollingworth Reservoir (now part of Swallows Wood nature reserve) was decommissioned and levelled and waters from the Ogden Brook fed into Arnfield. In 2004, two sections of the embankment were strengthened.
