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.

River Lea The River Lea in England originates in Marsh Farm, Leagrave, Luton in the Chiltern Hills and flows generally southeast, east, and then south through east London where it meets the River Thames, the last section being known as Bow Creek. It is one of the largest rivers in London and the easternmost major tributary of the Thames. Its valley creates a long chain of marshy ground along its lower length, much of which has been used for gravel and mineral extraction, reservoirs and industry. Much of the river has been canalised to provide a navigable route for boats into eastern Hertfordshire, known as the Lee Navigation. While the lower Lea remains somewhat polluted, its upper stretch and tributaries, classified as chalk streams, are a major source of drinking water for London. A diversion known as the New River, opened in 1613, abstracts clean water away from the lower stretch of the river for drinking. Its origins in the Chilterns contribute to the extreme hardness (high mineral content) of London tap water.

Cromwell Lock Cromwell Lock is a large navigation lock on the River Trent in Nottinghamshire, England. The first lock to be built on the site was constructed by the Trent Navigation Company, having been authorised by an Act of Parliament obtained in 1906. Construction began in late 1908, as soon as the Company had raised sufficient capital. The lock was extended in 1935, when an extra pair of gates were added downstream of the main lock, effectively forming a second lock. The lock was further improved in 1960, when the two locks were made into one, capable of holding eight standard Trent barges.

Water Act 1989 The Water Act 1989 (1989 c.15) is an Act of the Parliament of the United Kingdom that reorganised the bodies responsible for all aspects of water within England and Wales. Whereas previous legislation, particularly the Water Act 1973, had focused on providing a single unifying body with responsibility for all water-related function within a river basin or series of river basins, this legislation divided those functions up again, with water supply, sewerage and sewage disposal being controlled by private companies, and the river management, land drainage and pollution functions becoming the responsibility of the National Rivers Authority.
