Grahamstown Dam
Grahamstown Dam is a major off-stream earthfill Embankment dam with a controlled labyrinth spillway and baffle chute that stores water from the Williams River. The dam is located north of Newcastle and within the Port Stephens Council local government area in the Lower Hunter Region of New South Wales, Australia. The dam's main purpose is water supply; it provides about 40 per cent of the potable water for the Hunter region; and is the Hunter's largest drinking water supply dam. The impounded reservoir is called Grahamstown Lake or the Grahamstown Storage Reservoir. Location and features Grahamstown Dam is immediately adjacent to residential areas in the town of Raymond Terrace, less than from the Raymond Terrace CBD. Commenced in 1955, completed in 1965, and commissioned in 1969, Grahamstown Dam is a major dam that receives its main inflow from the Williams River as well as its own catchment. Water flows into the Grahamstown Dam from the Williams River, upstream f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Potable 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 due to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In New South Wales
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, tap water, human consumption, Industrial water, 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 Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam (Jordan), 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.

Government Of New South Wales
The Government of New South Wales, also known as the NSW Government, is the Australian state democratic administrative authority of New South Wales. It is currently held by a coalition of the Liberal Party and the National Party. The Government of New South Wales, a parliamentary constitutional monarchy, was formed in 1856 as prescribed in its Constitution, as amended from time to time. Since the Federation of Australia in 1901, New South Wales has been a state of the Commonwealth of Australia, and the Constitution of Australia regulates its relationship with the Commonwealth. Under the Australian Constitution, New South Wales, as with all states, ceded legislative and judicial supremacy to the Commonwealth, but retained powers in all matters not in conflict with the Commonwealth. Executive and judicial powers New South Wales is governed according to the principles of the Westminster system, a form of parliamentary government based on the model of the United Kingdom.

Irrigation In Australia
Irrigation is a widespread practice required in many areas of Australia, the driest inhabited continent, to supplement low rainfall with water from other sources to assist in growing crops and pasture. Overuse or poor management of irrigation is held responsible by some for environmental problems such as soil salinity and loss of habitat for native flora and fauna. Irrigation differs from dryland farming (farming relying on rainfall) in Australia in its level of intensity and production. Common crops produced using irrigation include rice, cotton, canola, sugar, various fruits and other tree crops and pasture, hay and grain for use in beef and dairy production. Surface irrigation is the most common irrigation method in Australia, with drip and center pivot also utilised. All rights to use and control water are vested in the state, which issues conditional entitlements for water use. The first large-scale irrigation schemes in Australia were introduced during the 1880s, part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tillegra Dam Proposal
Tillegra Dam was a proposed dam on the Williams River to be located northwest of Dungog, in the Hunter Region of New South Wales, Australia. It was first proposed in the 1970s but a formal proposal was not announced until 2006. Community opposition and changing needs saw the end of the proposal in November 2010. Hunter Water divested itself of its Tillegra landholding in 2015, permanently ending the proposal. Overview The Tillegra Dam was first proposed by Hunter Water in the 1970s, but was deferred indefinitely in the 1980s due to the success of user pays pricing. On 13 November 2006, the NSW Government announced proposals for a A$300 million dam at Tillegra to supply water to the Lower Hunter Region and Central Coast. The justification for the dam was based primarily on climate change and population growth in the Hunter Region. Opposition The No Tillegra Dam Group was formed to prevent the building of the dam. Opponents claimed the dam proposal was grossly excessive for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Highway (Australia)
Pacific Highway is a national highway and major transport route along the central east coast of Australia, with the majority of it being part of Australia's Highway 1. The highway and its adjoining Pacific Motorway between Brisbane and Brunswick Heads and Pacific Motorway between Sydney and Newcastle links the state capitals of Sydney in New South Wales with Brisbane in Queensland, approximately paralleling the Tasman Sea of the South Pacific Ocean coast, via Gosford, Newcastle, Taree, Port Macquarie, Kempsey, Coffs Harbour, Grafton, and Ballina. Additionally, between Brunswick Heads and Port Macquarie (excepting for a short stretch around Coffs Harbour), the road is also signed as Pacific Motorway, but has not been legally gazetted as such. Pacific Highway no longer includes former sections of the highway between Brunswick Heads and Brisbane that have been legally renamed. As such, the highway stops short of the Queensland border near the Gold Coast. It is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bentonite
Bentonite () is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite. Na-montmorillonite has a considerably greater swelling capacity than Ca-montmorillonite. Bentonite usually forms from the weathering of volcanic ash in seawater, or by hydrothermal circulation through the porosity of volcanic ash beds, which converts (devitrification) the volcanic glass ( obsidian, rhyolite, dacite) present in the ash into clay minerals. In the mineral alteration process, a large fraction (up to 40-50 wt.%) of amorphous silica is dissolved and leached away, leaving the bentonite deposit in place. Bentonite beds are white or pale blue or green (traces of reduced ) in fresh exposures, turning to a cream color and then yellow, red, or brown (traces of oxidized ) as the exposure is weathered further. As a swelling clay, bentonite has the ability to absorb large quantities of water, which increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raymond Terrace
Raymond Terrace is a town in the Hunter Region of New South Wales, Australia, about by road north of Newcastle on the Pacific Highway. Established in 1837 it is situated at the confluence of the Hunter and Williams rivers. The town was named after Lieutenant Raymond, who had explored the Hunter River in 1797 and described the terraced appearance of trees in the area. Governor Lachlan Macquarie camped in the area in 1818, using "Raymond Terrace" as the name for the place where his party had camped. At the Raymond Terrace had a population of 13,453. It is the administrative centre of the Port Stephens local government area as well as a service hub for surrounding rural areas. Geography Raymond Terrace is situated to the east of the Hunter and Williams rivers and consists of three distinct regions. The north and south regions are primarily rural/semi-rural and occupy approximately 74% of the town's land with only 3% of the population living in these areas. Most of the populat ...

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.
