We see large road tankers replenishing stocks at petrol stations but where do they get the petrol and diesel from? How is fuel moved around the country from the oil refineries and storage facilities? Did you realise there is a network of pipelines across the United Kingdom for just this very purpose.
The Linewatch web site gives information on this set up and includes maps of the pipelines.
As an example from the Esso oil refinery at Fawley just outside Southampton oil is sent along the Esso pipelines to West London, Heathrow, Purfleet, Avonmouth, Gatwick, and Birmingham.
