State-owned
State ownership, also called government ownership and public ownership, is the ownership of an industry, asset, or enterprise by the state or a public body representing a community, as opposed to an individual or private party. Public ownership specifically refers to industries selling goods and services to consumers and differs from public goods and government services financed out of a government's general budget. Public ownership can take place at the national, regional, local, or municipal levels of government; or can refer to non-governmental public ownership vested in autonomous public enterprises. Public ownership is one of the three major forms of property ownership, differentiated from private, collective/cooperative, and common ownership. In market-based economies, state-owned assets are often managed and operated as joint-stock corporations with a government owning all or a controlling stake of the company's shares. This form is often referred to as a state-o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir (water)
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

Giardia
''Giardia'' ( or ) is a genus of anaerobic flagellated protozoan parasites of the phylum Metamonada that colonise and reproduce in the small intestines of several vertebrates, causing the disease giardiasis. Their life cycle alternates between a swimming trophozoite and an infective, resistant cyst. ''Giardia'' were first described by the Dutch microscopist Antonie van Leeuwenhoek in 1681. The genus is named after French zoologist Alfred Mathieu Giard. Characteristics Like other diplomonads, ''Giardia'' have two nuclei, each with four associated flagella, and were thought to lack both mitochondria and Golgi apparatuses. However, they are now known to possess a complex endomembrane system as well as mitochondrial remnants, called mitosomes, through mitochondrial reduction. The mitosomes are not used in ATP synthesis the way mitochondria are, but are involved in the maturation of iron-sulfur proteins. The synapomorphies of genus ''Giardia'' include cells with duplicate org ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptosporidium
''Cryptosporidium'', sometimes informally called crypto, is a genus of apicomplexan parasitic alveolates that can cause a respiratory and gastrointestinal illness (cryptosporidiosis) that primarily involves watery diarrhea (intestinal cryptosporidiosis), sometimes with a persistent cough (respiratory cryptosporidiosis). Treatment of gastrointestinal infection in humans involves fluid rehydration, electrolyte replacement, and management of any pain. , nitazoxanide is the only drug approved for the treatment of cryptosporidiosis in immunocompetent hosts. Supplemental zinc may improve symptoms, particularly in recurrent or persistent infections or in others at risk for zinc deficiency. ''Cryptosporidium'' oocysts are 4–6 μm in diameter and exhibit partial acid-fast staining. They must be differentiated from other partially acid-fast organisms including ''Cyclospora cayetanensis''. General characteristics ''Cryptosporidium'' causes cryptosporidiosis, an infection tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raw Water
Raw water is water found in the environment that has not been treated and does not have any of its minerals, ions, particles, bacteria, or parasites removed. Raw water includes rainwater, ground water, water from infiltration wells, and water from bodies like lakes and rivers. Raw water is generally unsafe for human consumption due to the presence of contaminants. A major health problem in some developing countries is use of raw water for drinking and cooking. Without treatment, raw water can be used for irrigation, construction, or cleaning purposes.Perth W.A. (2016) What is Raw Water?. Vintage Road Haulage. http://www.vintageroadhaulage.com.au/faq/what-is-raw-water/ Farmers use it for watering their crops and give it to livestock to drink, storing it in man-made lakes or reservoirs for long periods of time. Construction industries can use raw water for making cement or for damping down unsealed roads to prevent dust rising. Raw water can also be used for flushing toilets and was ...

1998 Sydney Water Crisis
The 1998 Sydney water crisis involved the suspected contamination of the water supply system of Greater Metropolitan Sydney by the microscopic pathogens ''Cryptosporidium'' and '' Giardia'' between July and September 1998. Following routine water sampling and testing, over a series of weeks low level contaminants were found at Prospect, , Sydney Hospital, the NSW Art Gallery, Macquarie Street, Centennial Park, , , , and water treatment facilities at Warragamba, Nepean, , , Woronora, Macarthur, the Illawarra and Prospect. The reliability of these test results was subsequently called into doubt. Precautionary "boil water" alerts were raised covering several suburban areas for the period of the crisis. In response to the crisis, the Government of New South Wales established a Commission of Inquiry, chaired by jurist Peter McClellan as Commissioner. McClennan handed down his final report to the NSW Premier making ninety-one recommendations that led to the reorganisation ...
