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.
Crai Reservoir is a storage reservoir located in the Brecon Beacons National Park for the water supply to the city of Swansea in South Wales and was built between 1898 and 1908 by Swansea Corporation.
The Claerwen reservoir and dam in Powys, Wales, were the last additions to the Elan Valley Reservoirs system built to provide water for the increasing water demand of the city of Birmingham and the West Midlands. The dam is built mainly of concrete, with the exterior dam face in dressed stone. The dam is a gravity dam built upon solid rock foundations as the pressure of the reservoir behind should be in equilibrium with the total weight of the dam itself thus causing complete stability.
Talla Reservoir, located a mile from Tweedsmuir, Scottish Borders, Scotland, is an earth-work dam fed by Talla Water. The reservoir is supplemented by water from the nearby Fruid Reservoir. It was opened in 1905. To assist in bringing the materials for its construction, the Talla Railway was built.
Beacons Reservoir is the northernmost of the three reservoirs in the Taff Fawr valley in South Wales. It was built by Cardiff Corporation Waterworks between 1893 and 1897, and the water is impounded by an earth dam with a clay core. Since 1973 it has been owned by Welsh Water. As its name suggests, it is located in the Brecon Beacons National Park in the Powys unitary authority area and within the historic county boundaries of Breconshire.
The Talla Railway was a privately constructed railway line in southern Scotland. It was built 1895-97 to aid the construction of the Talla Reservoir, to serve the water demand of Edinburgh. The railway was about eight miles (13 km) long, running south from a connection with the Caledonian Railway's Peebles branch at Broughton. A private passenger service was operated for workmen on the reservoir construction.
Talybont Reservoir is the largest stillwater reservoir in the central Brecon Beacons at 318 acres (1.29 km2). Talybont-on-Usk is 1.5 miles (2.4 km) downstream of the dam.
Threipmuir Reservoir is a reservoir in the City of Edinburgh Council area, Scotland, UK. It is situated to the south of Edinburgh at the base of the Pentland Hills, two miles south of Balerno.
Harperrig Reservoir is a reservoir in West Lothian, Scotland, to the north of the Pentland Hills, four miles (6.4 km) south of Mid Calder. The Water of Leith flows through it, and nearby are Harlaw Reservoir and Threipmuir Reservoir. It has been proposed that the reservoir be designated as a local nature reserve to be managed by West Lothian Council.
Cobbinshaw Reservoir is a reservoir in West Lothian, Scotland. It is situated near the Pentland Hills, 5 km south of West Calder. The 310-acre (1.3 km2) site is a Site of Special Scientific Interest (SSSI) and is popular with wildfowl.
Baddinsgill Reservoir is a small reservoir in the Scottish Borders area of Scotland close to Carlops, West Linton, and the boundary with Midlothian. It is close to Baddinsgill House. The Lyne Water is dammed to form the reservoir, not the Baddinsgill Burn, which joins the Lyne Water further south, below the reservoir. The earth dam was faced with concrete blocks. In time these eroded and they were capped with 100 millimetres (3.9 in) of tarmac.
Glencorse Reservoir is a reservoir in Midlothian, Scotland, two miles west of Glencorse, in the Pentland Hills.
Edgelaw Reservoir is an artificial reservoir in Midlothian, Scotland, UK, four miles west of Temple.
Ystradfellte Reservoir is a water storage reservoir on the Afon Dringarth in the upland area of Fforest Fawr within the Brecon Beacons National Park in South Wales. It lies just north of the village of Ystradfellte in the county of Powys at OS Grid ref SN 946178.
Pontsticill Reservoir or Taf Fechan Reservoir is a large reservoir on the Taf Fechan lying partly in the county of Powys and partly within the county borough of Merthyr Tydfil in south Wales. It lies within the Brecon Beacons National Park and Fforest Fawr Geopark.
Chelker Reservoir is a man-made lake in North Yorkshire, England. It lies in the parish of Draughton, immediately north of the A65 road, between Skipton and the village of Addingham. It was put into service in 1866 and serves the Bradford area; it is currently owned by Yorkshire Water. The reservoir's main inflow is the River Wharfe.
James Jardine was a Scottish civil engineer, mathematician and geologist. He was the first person to determine mean sea level. He built tunnels and bridges, including for the Innocent Railway, and built reservoirs including Glencorse, Threipmuir, Harlaw for Edinburgh Water Company, and Cobbinshaw for the Union Canal.
Lindean is a village north of Selkirk and the Ettrick Water, in the Scottish Borders area of Scotland.
Edinburgh Water Company and its successors have provided a public water supply and latterly sewerage and sewage treatment services to the Scottish capital of Edinburgh since 1819. The original company was established to supply drinking water and did so until 1870, when it was taken over by a public Water Trust, with representatives from Edinburgh, Leith and Portobello. That in turn was taken over by Edinburgh Corporation and in 1975, responsibility passed to the Lothian Regional Council, as did the duty to provide sewerage and sewage treatment services. Both services were moved out of local authority control, and taken over by the East of Scotland Water Authority in 1996. The three Scottish regional water authorities were merged to form Scottish Water in 2002.
