[2] These would be pumped storage reservoirs to hold water abstracted from the Thames[3] receiving it from an aqueduct, then delivering it by another to treatment works for their supply pipes.

[4] To obtain full indemnity and a compulsory purchase standard mechanism they promoted the Staines Reservoir Bill of 1896.

Water was originally lifted from the aqueduct to the reservoirs by five steam driven engines, each with a capacity of 16 million gallons per day (72,737 m3/day).

In 1992 there was a proposal to increase the capacity of the reservoirs by raising the height of the dam walls and removing the dividing embankment.

From April 2020 a sheet pile cut-off wall was installed in two places to prevent leakage of water through the core of the south reservoir's embankment.

[8] The area has been designated a Site of Special Scientific Interest (SSSI) as it carries important wintering populations of tufted ducks, pochard, goosander and goldeneye.

[10] Water is drawn from the north side of the Thames about 300 yards above Bell Weir, at a decorative sluice house.

The water runs underground for about 350 yards in a north-east direction, it then flows in two steel siphons under the Colne Brook.

[11] From Sunbury Common the aqueduct changes direction to the north-east, it curves around the north side of Kempton Park race course with connections to Sunbury and Kempton Park water treatment works, and flows in a south-east direction into the Red House distribution reservoir (51°25'11.6"N 0°23'20.4"W).

[12] From here a pipeline and an open aqueduct takes water south to the reservoirs at the west end of Hampton waterworks.
