A major part of London's water supply infrastructure, the initial ring was constructed by Thames Water between 1988 and 1993 at a cost of £248 million (equivalent to £638 million in 2023), and when completed, it was the longest tunnel in the UK.[2][3] Two extensions were constructed between 2007 and 2010.[1]
