Water Tunnel (physical Infrastructure)
Water tunnels are tunnels (below-ground channels) used to transport water to areas with large populations or agriculture. They are frequently part of aqueducts. Some aqueducts, such as the Delaware Aqueduct are single long tunnels. In other cases, such as the San Jacinto tunnel on the Colorado River Aqueduct, water tunnels form parts of far longer aqueducts. In cases where the outflow of a water tunnel is into an existing stream or river flowing to the point of water use, the term aqueduct is less likely to be used, as with the Harold D. Roberts Tunnel from Dillon Reservoir to the North Fork South Platte River. Notable water tunnels, or systems including water tunnels * Alva B.

Aqueduct (watercourse)
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term ''aqueduct'' is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term ''aqueduct'' also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water. Etymology The word ''aqueduct'' is derived from the Latin words (''water'') and (''led'' or ''guided''). Ancient aqueducts Although particularly associated with the Romans, aqueducts we ...

Irtysh–Karamay–Ürümqi Canal
The Irtysh–Karamay–Ürümqi Canal (), also known as the Project 635 () Canal, is a system of water-transfer canals and reservoirs in the northern part of China's Xinjiang Uighur Autonomous Region. It transfers water from the Irtysh River (which flows toward the Arctic Ocean) into several dry endorheic basins of north-central Xinjiang, where it is used for irrigation and general use of the population and industries. The canal is often referred in Chinese publications simply the "Project for Supplying Water From the Irtysh" ("引额供水"工程). According to Chinese planners, the water carried by the canal will eventually irrigate 140,000 hectares of land. An important user of the canal's water is the petroleum industry around Karamay. History The ideas for redirecting some of the waters of the Irtysh for irrigation use in the (Soviet) Central Asia was actively discussed in the USSR in the mid-20th century. However, the bulk of the Soviet Northern river reversal project was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culvert
A culvert is a structure that channels water past an obstacle or to a subterranean waterway. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material. In the United Kingdom, the word can also be used for a longer artificially buried watercourse. Culverts are commonly used both as cross-drains to relieve drainage of ditches at the roadside, and to pass water under a road at natural drainage and stream crossings. When they are found beneath roads, they are frequently empty. A culvert may also be a bridge-like structure designed to allow vehicle or pedestrian traffic to cross over the waterway while allowing adequate passage for the water. Culverts come in many sizes and shapes including round, elliptical, flat-bottomed, open-bottomed, pear-shaped, and box-like constructions. The culvert type and shape selection is based on a number of factors including requirements for hydraulic performance, limitations on up ...

Canal Tunnel
{{Refimprove, date=September 2009 A canal tunnel is a tunnel for a canal. The building of a canal tunnel is crucial to help a waterway that is normally used for shipping cross a difficult section of terrain. They are also constructed to reduce the dependency on canal locks. The longest canal tunnel in the world is the Rove Tunnel in France, currently disused. Other notable examples of canal tunnels include the proposed Stad Ship Tunnel in Norway, a proposed tunnel for sea going vessels, Standedge Tunnel, the longest, deepest and highest in the United Kingdom and Harecastle Tunnel, another noteworthy tunnel in the UK. The oldest canal tunnel in the world is the Malpas Tunnel also in France, built in 1679. In some canal tunnels the towpath continues through the tunnel. In other cases, especially on English narrow canals, there is no towpath. The horse would be led over the hill and the boat would be propelled by legging. The term "canal tunnel" is not commonly applied to tunnel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Päijänne Water Tunnel
The Päijänne Water Tunnel (, ) is a water tunnel located in Southern Finland. At , it is the second-longest tunnel in the world, running at a depth of in the bedrock. The purpose of the tunnel is to provide fresh water for the over one million people of the Greater Helsinki area, including the cities of Helsinki, Espoo, Vantaa, Hyvinkää, Järvenpää, Kerava, Kauniainen, Kirkkonummi, Sipoo and Tuusula. The former Porvoo Rural Municipality, now merged with the municipality of Porvoo, also took part in the building of the scheme but has never drawn water from it for domestic use. The tunnel starts at Asikkalanselkä in Lake Päijänne, the second-largest lake in Finland with an area of . From there, the tunnel slopes slightly downhill allowing water to flow naturally with gravity. Water from the southern portion of Lake Päijänne is of good quality at the tunnel intake, and usually drinkable without processing. The tunnel ends at the Silvola reservoir in Vantaa. From ...

New York City Water Supply System
A combination of aqueducts, reservoirs, and tunnels supplies fresh water to New York City. With three major water systems ( Croton, Catskill, and Delaware) stretching up to away from the city, its water supply system is one of the most extensive municipal water systems in the world. New York's water treatment process is simpler than most other American cities. This largely reflects how well protected its watersheds are. The city has sought to restrict development surrounding them. One of its largest watershed protection programs is the Land Acquisition Program, under which the New York City Department of Environmental Protection (DEP) has purchased or protected, through conservation easement, over since 1997. With all the care given, the city's water supply system is partially exempted from filtration requirements by both the federal and the state government, saving more than "$10 billion to build a massive filtration plant, and at least another $100 million annually on it ...

San Jacinto Tunnel
The San Jacinto tunnel is considered the key link in Colorado River Aqueduct system. The 13 mi (21 km) long, 16 ft (4.9 m) diameter tunnel runs beneath the San Jacinto Mountains between Cabazon, California and Gilman Hot Springs in Riverside County, California. History The $23 million project started on April 8, 1933. Tunnel crews dug from four directions: the two main portals and two shafts. On July 1, 1934, one of the tunnel crews narrowly escaped the tunnel as ground water burst in and began filling the tunnel and shafts at a rate of nearly 8,000 US gallons per minute (0.50 m3/s). Metropolitan Water District of Southern California (MWD) Chief Engineer Frank E. Weymouth had noted in his 1930 report on the tunnel routes that the Parker route “involves less risk than any of the other proposed lines.” The continued intrusion of water was more than the original contractors could handle, and in February 1935 the MWD terminated the contract and took over the job.
