Millbrook Reservoir
Millbrook Reservoir is a 16,000-megalitre artificial water storage reservoir in the Adelaide Hills, South Australia. It was built from 1914 to 1918 during World War I to control water flows in the upper River Torrens and provide gravity-fed water to Adelaide's eastern suburbs. It is named after the small town of Millbrook, demolished and removed during construction. During the 1970s, the nearby town of Chain of Ponds was also removed to prevent pollution of the reservoir's water. Millbrook covers behind a clay-cored earth dam. It lies on Chain of Ponds creek, a tributary of the River Torrens. Water in the reservoir is piped from a weir near Gumeracha but it is also used to balance storage of River Murray water via the Mannum–Adelaide pipeline. It also captures approximately half of the Torrens' water flow. John Tippett named the town of Millbrook in the late 19th century after Millbrook in his native Cornwall Cornwall (; kw, Kernow ) is a historic county and cer ...

South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...

Gumeracha, South Australia
Gumeracha ( ) is a town in the Adelaide Hills, South Australia, located on the Adelaide-Mannum Road. It is located in the Adelaide Hills Council local government area on the south bank of the upper River Torrens. At the 2006 census, Gumeracha had a population of 731. The region relies heavily on grazing, dairying, grape growing, orchards and market gardening. History The original inhabitants of the area were the Peramangk people, and the name "Gumeracha" derives from an Aboriginal word meaning "fine waterhole". The area was one of the earliest settled by Europeans in South Australia. First to explore the district were Dr George Imlay and John Hill, on 24 January 1838. In 1839, the South Australia Company took up a parcel of land, on which the settlements of Gumeracha, Kenton Valley and Forreston developed. The company established a district headquarters and opened it up for sheep grazing. In 1841, The South Australian Company built a home for the first manager of the s ...

Dams Completed In 1918
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mannum–Adelaide Pipeline
The Mannum–Adelaide pipeline is a water pipeline in South Australia. It was the first major pipeline built from the River Murray to serve Adelaide. The pipeline project was started in 1949 and completed in March 1955. After suffering water restrictions every summer from 1949 to 1954, in the summer of 1957–1958 Adelaide was the only mainland capital not subject to restrictions. The pipeline, 60 kilometres long, goes from Mannum to Hope Valley. Off takes supply the Warren Reservoir transfer main, Little Para Reservoir dissipater and the treatment plants at Mannum, Palmer, Mt Pleasant and Anstey Hill. It is one of only two major pipelines in South Australia to supply Adelaide water from the River Murray, the other being the Murray Bridge-Onkaparinga Pipeline. They are also the only two that are used for bulk raw water transfer. From 2019, SA Water is seeking to reduce operating costs by installing a solar panel array to provide power for each pumping station on the route. S ...

River Murray
The Murray River (in South Australia: River Murray) (Ngarrindjeri: ''Millewa'', Yorta Yorta: ''Tongala'') is a river in Southeastern Australia. It is Australia's longest river at extent. Its tributaries include five of the next six longest rivers of Australia (the Murrumbidgee, Darling, Lachlan, Warrego and Paroo Rivers). Together with that of the Murray, the catchments of these rivers form the Murray–Darling basin, which covers about one-seventh the area of Australia. It is widely considered Australia's most important irrigated region. The Murray rises in the Australian Alps, draining the western side of Australia's highest mountains, then meanders northwest across Australia's inland plains, forming the border between the states of New South Wales and Victoria as it flows into South Australia. From an east–west direction it turns south at Morgan for its final , reaching the eastern edge of Lake Alexandrina, which fluctuates in salinity. The water then flows thro ...

Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water behind ...

Reservoir
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 A dam is a barrier that stops or restricts the flow of surface water or underground streams ...

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactiv ...
