Woronora Dam
The Woronora Dam is a heritage-listed concrete gravity dam with an uncontrolled serpentine spillway across the Woronora River, located south of Greater Metropolitan Sydney, in the suburb of Woronora Dam, Sutherland Shire, New South Wales, Australia. The principal purpose of the dam is for potable water supply for Sydney's southern suburbs and the northern suburbs of the Illawarra region. The impounded reservoir is also called Woronora Dam and is sometimes incorrectly called Lake Woronora. The dam was designed by G. E. Haskins, Chief Engineer and the Metropolitan Water, Sewerage and Drainage Board of NSW (MWS&DB) and built from 1927 to 1941 by the MWS&DB. The property is owned by the Sydney Catchment Authority, an agency of the Government of New South Wales. It was added to the New South Wales State Heritage Register on 18 November 1999. In 2009 the NSW State government granted the mining company Peabody conditional approval to mine for coal in the Reservoir catchment and d ...

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 ...

Government Agency
A government or state agency, sometimes an appointed commission, is a permanent or semi-permanent organization in the machinery of government that is responsible for the oversight and administration of specific functions, such as an administration. There is a notable variety of agency types. Although usage differs, a government agency is normally distinct both from a department or ministry, and other types of public body established by government. The functions of an agency are normally executive in character since different types of organizations (''such as commissions'') are most often constituted in an advisory role—this distinction is often blurred in practice however, it is not allowed. A government agency may be established by either a national government or a state government within a federal system. Agencies can be established by legislation or by executive powers. The autonomy, independence, and accountability of government agencies also vary widely. History Early exa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Nepean Scheme
The Upper Nepean Scheme is a series of dams and weirs in the catchments of the Cataract, Cordeaux, Avon and Nepean rivers of New South Wales, Australia. The scheme includes four dams and two weirs, and a gravity-fed canal system that feeds into a large storage reservoir to provide water to the Macarthur and Illawarra regions, the Wollondilly Shire, and metropolitan Sydney. The four dams and associated infrastructure are individually listed on the New South Wales State Heritage Register. History By 1867, Sydney was outgrowing the water supply available from Botany Swamps and the Governor ( Sir John Young) appointed a Commission to recommend a future water supply. In 1869, the Commission recommended the Upper Nepean Scheme. This comprised weirs on the Cataract and Nepean rivers, a storage reservoir at Prospect and of pipelines, tunnels, canals and aqueducts to bring water from the catchment area to Sydney. Work on the Scheme began in 1880 and was completed in 1888. The Sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helensburgh
Helensburgh (; gd, Baile Eilidh) is an affluent coastal town on the north side of the Firth of Clyde in Scotland, situated at the mouth of the Gareloch. Historically in Dunbartonshire, it became part of Argyll and Bute following local government reorganisation in 1996. Geography and geology Helensburgh is northwest of Glasgow. The town faces south towards Greenock across the Firth of Clyde, which is approximately wide at this point. Ocean-going ships can call at Greenock, but the shore at Helensburgh is very shallow, although to the west of the town the Gareloch is deep. Helensburgh lies at the western mainland end of the Highland Boundary Fault. This means that the hills to the north of Helensburgh lie in the Scottish Highlands, Highlands, whereas the land to the south of Helensburgh is in the Scottish Lowlands, Lowlands or Central Belt of Scotland. Consequently, there is a wide variety of landscape in the surrounding area – for example, Loch Lomond (part of Scotland's ...

The Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asbestos Cement
Asbestos cement, genericized as fibro, fibrolite (short for "fibrous (or fibre) cement sheet") or AC sheet, is a building material in which asbestos fibres are used to reinforce thin rigid cement sheets. Although invented at the end of the 19th century, the material was adopted extensively during World War II to make easily-built, sturdy and inexpensive structures for military purposes, and it continued to be used widely following the war as an affordable external cladding for buildings. Advertised as a fireproof alternative to other roofing materials such as asphalt, asbestos-cement roofs were popular, not only for safety but also for affordability. Due to asbestos-cement's imitation of more expensive materials such as wood siding and shingles, brick, slate, and stone, the product was marketed as an affordable renovation material. Asbestos-cement faced competition with the aluminum alloy, available in large quantities after WWII, and the reemergence of wood clapboard and v ...

Bungalow
A bungalow is a small house or cottage that is either single-story or has a second story built into a sloping roof (usually with dormer windows), and may be surrounded by wide verandas. The first house in England that was classified as a bungalow was built in 1869. In America it was initially used as a vacation architecture, and was most popular between 1900 and 1918, especially with the Arts and Crafts movement. The term bungalow is derived from the word and used elliptically to mean "a house in the Bengal style." Design considerations Bungalows are very convenient for the homeowner in that all living areas are on a single-story and there are no stairs between living areas. A bungalow is well suited to persons with impaired mobility, such as the elderly or those in wheelchairs. Neighborhoods of only bungalows offer more privacy than similar neighborhoods with two-story houses. As bungalows are one or one and a half stories, strategically planted trees and shrubs ...

Sutherland, New South Wales
Sutherland is a suburb in southern Sydney, in the state of New South Wales, Australia. Sutherland is located 26 kilometres south of the Sydney central business district and is the administrative centre for the local government area of the Sutherland Shire. History There are two theories for the origin of the Sutherland name: * It is suggested that the name was taken from able seaman Forby Sutherland, who died on Captain Cook's ''Endeavour'' voyage. Sutherland Point at Kurnell is named after him, but there's no direct connection of him to the Sutherland Shire district. * Thomas Mitchell as surveyor general in 1835 named the first parish south of the Georges River as the " Parish of Southerland" (South with an "o"). But it appeared in a later government gazette spelt Sutherland, losing the significance of the name. Thomas Holt (1811–88) purchased 13,000 acres (53 km2) in the 1860s that stretched from Sutherland to Cronulla. The Sutherland area was originally heavily t ...

Miranda, New South Wales
Miranda () is a suburb in southern Sydney, in the state of New South Wales, Australia. The suburb is known as a commercial centre for the southern suburbs. Miranda is 24 kilometres south of the Sydney central business district, in the Sutherland Shire. History Thomas Holt (1811–88) owned the land that stretched from Sutherland to Cronulla. James Murphy, the manager of the Holt estate named the area after Miranda, a character in the William Shakespeare play '' The Tempest''. In a 1921 letter, James Murphy said "the name Miranda was given to the locality by me as manager of the Holt Sutherland Company which I formed in 1881. I thought it a soft, euphonious, musical and appropriate name for a beautiful place." It is believed that the character in the play was named after Miranda de Ebro, a town in Spain. Early Australian explorer Gregory Blaxland was promised a significant parcel of land in the area as a reward for discovering a passage through the Blue Mountains. He had not s ...
