Caban-coch Reservoir
The Elan Valley Reservoirs () are a chain of man-made lakes created from damming the Elan and Claerwen rivers within the Elan Valley in Mid Wales. The reservoirs, which were built by the Birmingham Corporation Water Department, provide clean drinking water for Birmingham in the West Midlands of England. The five lakes are known as the Claerwen, Craig-goch, Pen-y-garreg, Garreg-ddu, and Caban-coch. Water from the reservoirs is carried by gravity to Frankley Reservoir in Birmingham via the Elan aqueduct. Pumping is not required because the network drops along its length from its source to Frankley. A gradient of 1:2,300 maintains a flow of less than ; water takes one and a half to two days to reach Birmingham. The aqueduct, which was started in 1896 and opened in 1906, crosses several valleys and features numerous brick tunnels, pipelines, and valve houses. Work to build the Elan Valley reservoirs was undertaken because the rapid growth of the industrial city of Birmingha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elan Valley
The Elan Valley () is a river valley situated to the west of Rhayader, in Powys, Wales, sometimes known as the "Welsh Lake District". It covers of lake and countryside. The valley contains the Elan Valley Reservoirs and Elan Village, designed by architect Herbert Tudor Buckland as part of the same scheme. Elan Village is the only purpose-built Arts and Crafts "Model Village" in Wales. It is also famous for its picturesque scenery. Over 80% of the valley is designated as Sites of Special Scientific Interest, and a popular cycle trail, the Elan Valley Trail, makes a loop from Rhayader around the reservoirs. Part of the trail overlaps with a spur of National Cycle Route 81 (''Lon Cambria''). As of 2015 it is an International Dark Sky Park.

Barnes Wallis
Sir Barnes Neville Wallis (26 September 1887 – 30 October 1979) was an English engineer and inventor. He is best known for inventing the bouncing bomb used by the Royal Air Force in Operation Chastise (the "Dambusters" raid) to attack the dams of the Ruhr Valley during World War II. The raid was the subject of the 1955 film '' The Dam Busters'', in which Wallis was played by Michael Redgrave. Among his other inventions were his version of the geodetic airframe and the earthquake bomb, including designs such as the Tallboy and Grand Slam bombs. Early life and education Barnes Wallis was born in Ripley, Derbyshire, to general practitioner Charles George Wallis (1859–1945) and his wife Edith Eyre (1859–1911), daughter of Rev. John Ashby. The Wallis family subsequently moved to New Cross, south London, living in "straitened, genteel circumstances" after Charles Wallis was crippled by polio in 1893. He was educated at Christ's Hospital in Horsham and Haberdas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Craig Goch Dam
The Craig Goch Dam, often called the Top dam, is a masonry dam in the Elan Valley of Wales and creates the upper-most of the Elan Valley Reservoirs. Construction on the dam began in 1897, and it was completed in 1904. The primary purpose of the dam and the other reservoirs is to supply Birmingham with water. In 1997, a 480 kW hydroelectric generator began operation at the dam. Craig Goch Dam views.jpg Craig Goch Dam.jpg Potential river transfer scheme The Craig Goch reservoir had been identified in the 1970s and in the 1990s as a potential source of water for the south-east of England. The latest project envisaged raising the existing dam, adding a secondary dam at the head of the River Ystwyth valley and piping water from the high head generated into the River Severn and subsequently transferring it by pipeline aqueduct to the head-waters of the River Thames in the Cotswolds.

Litre
The litre ( Commonwealth spelling) or liter ( American spelling) (SI symbols L and l, other symbol used: ℓ) is a metric unit of volume. It is equal to 1 cubic decimetre (dm3), 1000 cubic centimetres (cm3) or 0.001 cubic metres (m3). A cubic decimetre (or litre) occupies a volume of (see figure) and is thus equal to one-thousandth of a cubic metre. The original French metric system used the litre as a base unit. The word ''litre'' is derived from an older French unit, the '' litron'', whose name came from Byzantine Greek—where it was a unit of weight, not volume—via Late Medieval Latin, and which equalled approximately 0.831 litres. The litre was also used in several subsequent versions of the metric system and is accepted for use with the SI, despite it not being an SI unit The International System of Units, internationally known by the abbreviation SI (from French ), is the modern form of the metric system and the world's most widely used system of unit ...

Water Purification
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water that is fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications. The history of water purification includes a wide variety of methods. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light. Water purification can reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, and fungi as well as reduce the concentration ...

Hard Water
Hard water is water that has a high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Drinking hard water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of foam formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters. Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects. Origins Natural rainwater, snow and other forms of precipitation typically have low concentrations of divalent cations such as calcium and magnesium. They may have small concentrations of ion ...

Water Softening
Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating Fouling#Precipitation fouling, scale build-up in pipes and fittings. Water softening is usually achieved using lime softening or ion-exchange resins, but is increasingly being accomplished using nanofiltration or reverse osmosis membranes. Rationale The presence of certain metal ions like calcium and magnesium, principally as bicarbonates, chlorides, and sulfates, in water causes a variety of problems. Hard water leads to the buildup of limescale, which can foul plumbing, and promote galvanic corrosion. In industrial scale water softening plants, the effluent flow from the re-generation process can precipitate scale that can interfere with sewage systems. The slippery feeling associ ...

Elan Village
Elan Village () is a small purpose-built community in Powys, Wales. It was designed by architect Herbert Tudor Buckland as part of Birmingham Corporation's scheme to construct a series of water supply reservoirs in the Elan Valley between 1892 and 1904. It housed workers and their families responsible for maintaining the scheme's dams and the filtration systems. Elan Village is the only purpose-built Arts and Crafts movement, Arts and Crafts "model village" in Wales. It is served by the B4518 road which runs three miles southwestwards from Rhayader to end at the village, though continuing as a minor road to Caban-coch reservoir. The road continues over the Elenydd to Cwmystwyth and a cul-de-sac branch runs to the dam of Claerwen reservoir.Ordnance Survey 1:25,000 scale Explorer map sheet no 200 ''Llandrindod Wells & Elan Valley'' It is in the Community (Wales), community of Rhayader.
