Grand Junction Isle
Grand Junction Isle is a small island in the River Thames on the reach above Molesey Lock at Sunbury-on-Thames, Surrey, England. It is just downstream of Sunbury Court Island, which is three times longer and also close to the north bank.
The island is more of a lozenge than ellipse and at its greatest extent 35m long and 15m wide within the low lying tree-covered somewhat tenuous land of the island are no more than three weekend chalets of garden summerhouse size with mooring spaces and is connected to the northern bank in the residential far south-east of Sunbury by a footbridge.<ref name=os>Grid square map Ordnance survey website</ref>
The island takes its name from the Grand Junction Waterworks Company which was one of three companies operating its 'Hampton Water Works' which straddle the Hampton/Sunbury border such that the border has been moved to accommodate the westernmost reservoir within Hampton. The company built a water intake on the island to feed that reservoir and others, which in turn feed into filter beds, filters and advanced chemical and electromagnetic treatment works owned and operated by Thames Water. The island was previously known as "Purvis Ait".
