Wilton Water
Wilton Water (or Wide Waters) is a small reservoir, southwest of the village of Great Bedwyn in the English county of Wiltshire, which supplies the summit pound of the Kennet and Avon Canal with water. The reservoir lies in the parish of Grafton and collects rainfall from the eastern end of the Vale of Pewsey and the surrounding hills. It was created by John Blackwell in 1836, by damming a narrow branching valley, and is fed by natural springs. In addition to supplying water for the canal, which is pumped by Crofton Pumping Station, it provides a haven for wildlife. It has been stocked with rainbow trout. When the canal was built, there were no reliable water sources available to fill the summit by normal gravitational means. However, a set of usable springs were found adjacent to the canal route about one mile (2 km) east of the summit pound, and about 40 feet (12 m) below it. Arrangements were made for these springs to feed the pound below lock 60 at Crofton Locks. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crofton Pumping Station
Crofton Pumping Station, near the village of Great Bedwyn in Wiltshire, England, supplies the summit pound of the Kennet and Avon Canal with water. The steam-powered pumping station is preserved and operates on selected weekends. It contains an operational Boulton & Watt steam engine dating from 1812, making it the oldest working beam engine in the world in its original engine house and capable of doing the job for which it was installed. Description When the canal was built, no reliable water sources were available to fill the summit by normal gravitational means. However, a set of usable springs were found adjacent to the canal route about east of the summit pound, and about below it. Arrangements were made for these springs to feed the pound below lock 60 at Crofton Locks. Some years later a reservoir ( Wilton Water) was created to improve the supply to this pound, and this can now be seen across the canal from the pumping station. Water from below lock 60 was take ...

Canal Lock
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls.) Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension of the flash lock, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of The British Canal System
The canal network of the United Kingdom of Great Britain and Ireland, United Kingdom played a vital role in the Industrial Revolution. The UK was the first country to develop a nationwide canal network which, at its peak, expanded to nearly in length. The canals allowed raw materials to be transported to a place of manufacture, and finished goods to be transported to consumers, more quickly and cheaply than by a land based route. The canal network was extensive and included feats of civil engineering such as the Anderton Boat Lift, the Manchester Ship Canal, the Worsley Navigable Levels and the Pontcysyllte Aqueduct. In the post-medieval period, some rivers were canalised for boat traffic. The Exeter Ship Canal was completed in 1567. The Sankey Canal was the first British canal of the Industrial Revolution, opening in 1757. The Bridgewater Canal followed in 1761 and proved to be highly profitable. The majority of the network was built in the "Golden Age" of canals, between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canals Of The United Kingdom
The canals of the United Kingdom are a major part of the network of inland waterways in the United Kingdom. They have a History of the British canal system, varied history, from use for irrigation and transport, through becoming the focus of the Industrial Revolution, to today's role of recreational boating. Despite a period of abandonment, today the canal system in the United Kingdom is again increasing in use, with abandoned and derelict canals being reopened, and the construction of some new routes. Canals in England and Wales are maintained by List of navigation authorities in the United Kingdom, navigation authorities. The biggest navigation authorities are the Canal & River Trust and the Environment Agency, but other canals are managed by companies, local authorities or charitable trusts. The majority of List of canals of the United Kingdom, canals in the United Kingdom can accommodate boats with a length of between and are now used primarily for leisure. There are a number ...

Grade II Listed
In the United Kingdom, a listed building is a structure of particular architectural or historic interest deserving of special protection. Such buildings are placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, in Wales, and the Historic Environment Division of the Department for Communities in Northern Ireland. The classification schemes differ between England and Wales, Scotland, and Northern Ireland (see sections below). The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000, although the statutory term in Ireland is " protected structure". A listed building may not be demolished, extended, or altered without permission from the local planning authority, which typically consults the relevant central government agency. In England and Wales, a national amenity society must be notified of any work to be done on a listed building ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crofton Locks
Crofton Locks are a flight of Canal lock, locks on the Kennet and Avon Canal, near the village of Great Bedwyn, Wiltshire, England. The nine locks achieve a total rise/fall of 61 ft 0 in (18.5 m) and were built under the supervision of engineer John Rennie the Elder, John Rennie. West of the top lock is the summit of the canal at 450 ft (137 m) above sea level. Lockage water is taken from Wilton Water to the summit at the western end of the locks by electric pumps and, on occasion, by the restored Crofton Pumping Station. Location Although named for Crofton in the civil parish of Great Bedwyn the locks are actually situated in the parish of Grafton, Wiltshire, Grafton, as the parish boundary at this point is the West of England Main Line to the north of the canal.

Spring (hydrosphere)
A spring is a natural exit point at which groundwater emerges from an aquifer and flows across the ground surface as surface water. It is a component of the hydrosphere, as well as a part of the water cycle. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and Hydrostatics#Hydrostatic pressure, hydrostatic pressure. A spring produced by the emergence of Geothermal activity, geothermally heated groundwater is known as a hot spring. The yield (hydrology), yield of spring water varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the water table reaches above the surface level, or if the terrain depression (geology), depresses sharply. Springs may also be formed ...

John Blackwell (engineer)
John Blackwell (c. 1775 – 1840) was an English civil engineer, known for his work as superintending engineer of the Kennet and Avon Canal under John Rennie the Elder, John Rennie and later as the canal company's resident engineer. Career Blackwell was employed as an engineer on the Kennet and Avon Canal in 1806, working primarily as site agent on the Caen Hill Flight in Devizes, Wiltshire. While John Rennie the Elder, John Rennie designed the Lock flights, flight, it was likely that construction was undertaken by the Kennet and Avon Canal Company and its engineers. In 1808, shortly before the completion of the flight, Blackwell moved to work with Rennie on Crofton Pumping Station. The following year, the pair built the remaining locks on the canal—two pound locks Oakhill Down near Froxfield, which replaced an earlier single deeper lock. Original plans would have seen the lock be the canal's only staircase lock, staircase, although this proposal was never seen through. Blac ...
