In what year was the River Lea constructed as part of the London water supply infrastructure?
London water supply infrastructure London's water supply infrastructure has developed over the centuries in line with the expansion of London. For much of London's history, private companies supplied fresh water to various parts of London from wells, the River Thames and in the three centuries after the construction in 1613 of the New River, the River Lea, which has springs that divert alongside Hertford at an elevation of 40 metres AOD. Further demand prompted new conduits and sources, particularly in the 150 years to 1900 as the Agricultural and Industrial Revolution caused a boom in London's population and housing.
