Anglezarke Reservoir
Encyclopedia
Anglezarke Reservoir is the largest reservoir
in the Rivington
chain to the west of Anglezarke
in Lancashire
, England. Anglezarke Reservoir has three embankments, the longest, the Charnock Embankment is 777 metres long and 9.45 metres high, the Knowsley Embankment is 219.5 metres long and 14 metres high while the Heapey
Embankment is 85.3 metres long and 9.75 metres high. It is feed 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. The scheme was to construct five reservoirs and a water treatment works at the south end of Lower Rivington with a 17-mile 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 a particularly dry summer. 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. The condition of the embankment and surrounding strata
were such that a phased grout
ing operation was required to remedy the leakage. The reservoir was refilled, but was still leaking. After a second grouting and refill operation, the embankment was deemed leak-free.
It appears that the original cause of the leak was an 18" cast iron drawoff pipe which supplied White Brook to the north of the embankment. The trench for the pipe was cut much deeper than needed, through a glacial
meltwater channel. However, shutting the pipe off in the 1970s failed to remedy the situation.
Waterman's Cottage was built by Liverpool Corporation on the west bank of the reservoir. The cottage is a-Tudor
style structure also known as Heapey Cottage. It was occupied by Denis and Anne Oakden in the 1940s. Denis worked for the Water Authority and moved to the property after several years in Porch Cottages, White Coppice
.
To the east of the reservoir is the small High Bullough reservoir
and the Anglezarke Moors, Upper Rivington Reservoir
is to the south and Healey Nab
to the north west. The area is now a wildlife haven, with a Woodland Trail which links to High Bullough reservoir.
