Bolmen Water Tunnel
The Bolmen Water Tunnel ( sv, Bolmentunneln) is a water supply tunnel, long. It goes from the lake Bolmen in Kronoberg County to the province of Skåne, all in Sweden, and it serves around 700,000 people with drinking water. It has a cross section area of 9 m², a diameter of more than 3 m. About 2 m³/s is transported through the tunnel, although the capacity is 6 m³/s. The tunnel was built during the period 1975 to 1987. Background The tunnel was built because of the foreseen lack of tap water because of the growth of the population in the province of Scania in the 1960s and the high calcium level of the local water. That water was groundwater or came from the lakes of Ringsjön and Vombsjön Vombsjön (sometimes called ''Våmbsjön'') is a lake in Scania, Sweden. It is located 20 km to the east of Lund and lies in the municipalities of Lund, Eslöv and Sjöbo. The lake has been the source of drinking water for Malmö Malmö ....

Bolmen
Bolmen () is a lake in Småland, Sweden. Covering 184 km², and with a maximum depth of 37 m, it supplies a considerable part of Skåne with fresh water by means of an 82-km long tunnel, the Bolmen Water Tunnel, built during the 1970s and 80s. Bolmen is situated at the heart of Finnveden, one of the ''small lands'' of today's Småland. It is the tenth largest lake in Sweden. It contains 365 islands, of which the largest is Bolmsö, which was historically the meeting-place of the local assembly Assembly may refer to: Organisations and meetings * Deliberative assembly, a gathering of members who use parliamentary procedure for making decisions * General assembly, an official meeting of the members of an organization or of their representa ....

Skåne
Scania, also known by its native name of Skåne (, ), is the southernmost of the historical provinces (''landskap'') of Sweden. Located in the south tip of the geographical region of Götaland, the province is roughly conterminous with Skåne County, created in 1997. Like the other former provinces of Sweden, Scania still features in colloquial speech and in cultural references, and can therefore not be regarded as an archaic concept. Within Scania there are 33 municipalities that are autonomous within the Skåne Regional Council. Scania's largest city, Malmö, is the third-largest city in Sweden, as well as the fifth-largest in Scandinavia. To the north, Scania borders the former provinces of Halland and Småland, to the northeast Blekinge, to the east and south the Baltic Sea, and to the west Öresund. Since 2000, a road and railway bridge, the Öresund Bridge, bridges the Sound and connects Scania with Denmark. Scania forms part of the transnational Øresund Region. ...

Drinking Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross Section (geometry)
In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher- dimensional spaces. Cutting an object into slices creates many parallel cross-sections. The boundary of a cross-section in three-dimensional space that is parallel to two of the axes, that is, parallel to the plane determined by these axes, is sometimes referred to as a contour line; for example, if a plane cuts through mountains of a raised-relief map parallel to the ground, the result is a contour line in two-dimensional space showing points on the surface of the mountains of equal elevation. In technical drawing a cross-section, being a projection of an object onto a plane that intersects it, is a common tool used to depict the internal arrangement of a 3-dimensional object in two dimensions. It is traditionally crosshatched with the style of crosshatching often indicating the types of materials being used. Wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calcium
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin ''calx'' " lime", which was obtained from heating limestone. Some calcium compounds were known to the ancients, though their chemistry was unknown until the seventeenth century. Pure calcium was isolated in 1808 via electrolysis of its oxide by Humphry Davy, who named the element. Calcium compounds are widely used in many industries: in foods and p ...

Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, per ...

Ringsjön
Ringsjön is a lake situated in the middle of Skåne County, Sweden. At , it is the second largest lake in the county. The western and eastern parts of the lake, called Västra Ringsjön and Östra Ringsjön respectively, are separated by a headland. Västra Ringsjön has a depth of at its deepest known point, while Östra Ringsjön has a depth of . Ringsjön provides drinking water for the inhabitants of Skåne if the water tunnel connected to the lake Bolmen would cease to work. This happened in 2009, when the tunnel was almost completely blocked after a collapse. Fish species found in Ringsjön are European perch, carp bream, moderlieschen, northern pike, zander, common carp, burbot, common roach, rainbow trout, crucian carp, common rudd, common whitefish, tench, eel, and brown trout. Ringsjön has had an overpopulation of carp bream and common roach for a long time, leading to an increased algal bloom, and in 2005 work began on removing 80% of these species from the lake. ...

Water Tunnels
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers ...
