Anglezarke Reservoir

About

Anglezarke Reservoir is the largest reservoir in the Rivington chain to the west of Anglezarke in Lancashire, England. Anglezarke Reservoir has three embankments: the Charnock Embankment, the longest, is 850 yards (777 m) long and 31 feet (9.45 m) high, the Knowsley Embankment is 240 yards (219.5 m) long and 45 feet (14 m) high and the Heapey Embankment is 280 feet (85.3 m) long and 32 feet (9.75 m) high. It is fed by the River Yarrow, which has been diverted from its original course which is now covered by the Knowsley Embankment. It served the city of Liverpool before its current status as a supply mainly for Wigan. The original `Rivington Pike Scheme' was undertaken by Thomas Hawksley between 1850 and 1857 for the Liverpool Corporation Waterworks. The scheme was to construct five reservoirs and a water treatment works at the south end of Lower Rivington with a 17-mile (27 km) pipeline to storage reservoirs at Prescot. Water from two higher level reservoirs, Rake Brook and Lower Roddlesworth, was carried south in `The Goit', a channel connecting them to the reservoirs. In November 1997, the reservoir was refilled after the 1997 summer heat wave. The water flow was so large that the reservoir required an emergency draw-down. With the water level at a temporary low, there was an opportunity to inspect the Heapey embankment on Moor Road, which had been leaking since the 1960s
