The New River is an artificial waterway in England, opened in 1613 to supply London with fresh drinking water taken from the River Lea and from Chadwell Springs and, originally, Amwell Springs, as well as other springs and wells along its course.

The river follows the land contours but certain parts have been straightened over the centuries. Although it was at one time threatened with closure, the waterway continues to supply water to the capital. There is a designated walking route along the canal called the New River Path. It is a 28-mile (45 km) long-distance footpath which follows the course of the New River as closely as possible from its source in Hertfordshire to its original end in Islington, London.


It starts between Ware and Hertford in Hertfordshire and today runs 20 miles (32 km) down to Stoke Newington. Among the districts it flows through are (from north to south):

Its original termination, near Clerkenwell, Islington, became known as the New River Head where the water filled a large cistern - the Round Pond - next to the current location of Sadler's Wells theatre — where water from the river was used to flood a large tank to stage an Aquatic Theatre at the beginning of the nineteenth century. In 1946, the water supply to New River Head was truncated at Stoke Newington with the New River ending at the East Reservoir. The reservoir is managed as the Woodberry Wetlands – a nature reserve and designated Site of Metropolitan Importance.

The design and construction of the New River is often attributed solely to Sir Hugh Myddelton. Edmund Colthurst first proposed the idea in 1602, obtaining a charter from King James I in 1604 to carry it out. After surveying the route and digging the first 2 miles (3 km) stretch, Colthurst encountered financial difficulties and it fell to Myddelton to complete the work between 1609 and its official opening on 29 September 1613. The project was also rescued by the King personally, whose house and lands at Theobalds Park were crossed by the river. James took half of the shares in 1612 for a half of the profits. In order to give the project a firmer legal and financial structure, The New River Company was incorporated in 1619 by Royal Charter, with the assistance of Sir John Backhouse. The company's first reservoir was built on his land in Islington. Myddelton gave some of the shares in the New River Company to Colthurst.

The expense and engineering challenges of the project—it relied on gravity to allow the water to flow, carefully following the contours of the terrain from Ware into London, and dropping around just five inches per mile (8 cm/km)—were not Myddelton's only worries. He also faced considerable opposition from landowners who feared that the New River would reduce the value of their farmland (they argued that floods or overflowing might create quagmires that could trap livestock); others were concerned at the possible disruption to road transport networks between Hertfordshire and the capital. The project nearly foundered when a few landowners flatly refused to agree to allow the river across their land. At the time, it was proposed that a project of King James for a College in Chelsea would be funded by the proceeds of a rival project to supply water to London, and this may have spurred the New River's opponents, possibly even with royal encouragement. After that project failed, Myddelton was eventually strongly supported by the king, who agreed to pay half the project's expenses in return for a 50% shareholding; such backing quickly silenced the scheme's critics.

When it was originally constructed, long sections, for example around Forty Hall and in Hornsey, wound around the heads of small tributary valleys of the Lea. Other sections of the river, including the one in Harringay, were carried across valleys in wooden aqueducts lined with lead and supported by strong timbers and brick piers. In at least one section, locals referred to the river as the boarded river. Improvements in canal construction in the eighteenth century led to these sections being replaced by clay-banked canals.

On 9 January 1622 King James rode from Theobalds after dinner to see the ice on the New River and fell in head first so that his companions could only see his boots. He was rescued by Sir Richard Young and returned to a warm bed at Theobalds.

New River Company

The New River Company was incorporated by royal charter in 1619 with Sir Hugh Myddleton as first governor. Under the charter, it was a penal offence to throw rubbish or carrion into the river, while anyone washing clothes in it or planting sallow, willow or elm trees within five yards of it would incur the "King's displeasure".

The company became a significant landowner in the Clerkenwell district of Islington and laid out streets and squares which take their name from people and places associated with the company, including Amwell Street, River Street, Mylne Street, Chadwell Street and Myddelton Square.

When London's population grew beyond a million inhabitants, the "New River" failed to give an adequate supply of water, and other companies were formed for the purpose of supplying different parts of London: Chelsea Waterworks and others were started by various companies in succession. This company's water was often by commissions found purer than the others. It was also, due to its source, not impacted by the ban on the supply of drinking water from the tidal Thames under the Metropolis Water Act 1852 from 1 August 1855. After this the company continued to focus on its quality.

Dr. Frankland's analysis of water supplied to London during the month of October 1876 gave a relative degree of organic impurity compared to a given volume of the Kent Company's water. He also compared the samples from those of August and September. Organic impurity was measured relative to the Kent Water Company's benchmark, who supplied part of London (in areas, in direct competition with the others). The figures were:

Competing company Relative impurity
New River 0.9
Kent 1
East London 2.4
West Middlesex 2.8
Grand Junction 3.3
Lambeth 4.1
Chelsea 4.2
Southwark 4.5

The water delivered by the latter five companies, drawing their supply exclusively from the Thames, when compared with that supplied in August and September, showed a marked deterioration in quality. It had a higher proportion of contamination with organic matter.

The New River Company was taken over by the Metropolitan Water Board in 1904 and became part of Thames Water in 1973. The northern part of the New River is still an important link in the supply of water to London.

The company's former headquarters and laboratory at New River Head on Rosebery Avenue are now private flats; during daylight hours there is public access to a viewpoint over the gardens and into the adjacent garden of Nautilus House. At the rear of the building (not open to the public but visible from the gardens) are the remains of the 'Chimney' or 'Devil's' Conduit, the medieval conduit-head of the water supply of the London Greyfriars, discovered in Bloomsbury in 1911 and re-erected here in 1927.

Later alterations

A winding original section of the channel that used to run through the town centre of Enfield has been cut off from the main flow, but is still maintained as an important local civic amenity called the New River Loop.

Another large loop originally ran around the Devonshire Hill area in north Wood Green and southern Enfield. This loop was cut off when the Wood Green tunnel, which starts at Bowes Park, was completed in 1852. The loop existed for some decades, but was completely filled in and lost by the early 1900s. Now entirely covered by residential development dating mostly back to the 1930s, its former course is visible on numerous maps drawn in the 1800s and early 1900s.

Originally the course was above-ground throughout, but in the second half of the nineteenth century some sections were put underground, enabling the course to be straightened. In 1946 the River ceased to run above ground beyond the 1830s East Reservoir near Stoke Newington, now renamed Woodberry Wetlands, into which its flow is now entirely diverted. The picture (right) shows a short recreated stretch of the River in Hackney. Beyond here, the River used to run along the route of Petherton Road in Highbury.

The New River Aqueduct (51°40'58.6"N 0°03'16.0"W) was built in 1985 to carry the New River, then running on an embankment, over the London Orbital Motorway (M25) which was then being constructed. The aqueduct carries the river in two parallel concrete boxes each 90 m long, 4.25 m wide and 2 m deep. The double box design allowed the temporary diversion of the river during construction and also enables maintenance to be undertaken on either side without stopping the flow.

The route of the New River now provides a walking route through Islington. From Clissold Park, its route along the broad verge down the centre of Petherton Road leads to Essex Road, where another redundant section of the New River's course between Canonbury and Islington town centre forms a path alongside the now shallow stream, recreated as part of a linear park. At Canonbury Road, the walk continues through a fernery to Pleasant Place, where an inscription in the pavement marks the New River's route. At Islington Green, there is a statue of Sir Hugh Myddelton; the route continues along Colebrooke Row and Duncan Terrace to the Angel, then through Owen's Field to the New River Head between Amwell Street and Rosebery Avenue. The New River's course between Balls Pond Road and Essex Road, and along Colebrooke Row up to City Road, is marked by white boulders.

The Dame Alice Owen's School bombing

On 15 October 1940, approximately 150 people were sheltering in the basement of Dame Alice Owen's School, then situated on Goswell Road. A large parachute mine hit the building directly, causing the structure to collapse and blocking access to the basement. The blast wave from the bomb caused the pipeline carrying the New River to rupture, flooding the shelter and killing the majority of the people taking cover.

A memorial to the victims of the bombing stands in Owen's Fields at the northern end of Goswell Road.
