70-578: Taff Vale may refer to: The valley of the River Taff in South Wales surrounded by the communities of Ynysybwl|Ynysybwl & Coed-y-Cwm, Pontypridd and Taffs Well Taff Vale Railway , a Welsh railway line Taff Vale Railway Co. v. Amalgamated Society of Railway Servants , a 1901 court case Topics referred to by the same term [REDACTED] This disambiguation page lists articles associated with

140-542: A branch of the Taff Vale Railway over the river to Albion Colliery at Cilfynydd . Just to the south is White or Berw Bridge, designed by Pontypridd Urban District Council's surveyor, P R A Willoughby. It was built in 1907, aided by L G Mouchel & Partners, who pioneered the use of reinforced concrete, and the 115-foot (35 m) span over the river was the longest arch in Britain using this material when it

210-545: A clay core. The clay had to be imported, and for this purpose a private branch line was built from the Brecon and Merthyr Tydfil Junction Railway near Torpantau railway station . The contract for the work was given to William Jones of Neath, and the project was completed in 1884. Now decommissioned, the water level when the reservoir was full was at 1,413 feet (431 m) above Ordnance Datum , and it held 74 million imperial gallons (340 Ml). The Upper Neuadd Reservoir

280-602: A few tributaries, such as the River Cynon , River Rhondda , Bargoed Taf and Nant Clydach . It flows through Pontypridd and through to Taff's Well , the site of Wales' only thermal spring. It flows underneath the M4 Motorway , before turning southeastward and flowing past the Cardiff suburbs of Radyr , Whitchurch , Llandaff , Pontcanna , the city centre and Grangetown , before emptying into Cardiff Bay , near to

350-563: A new section which was part of the northern extension, but the difficulties were eventually resolved, and the track was reinstated in April 1893. The Board of Trade approved the plans for the extension on 27 April 1893 and by June, two timber viaducts had been built, to carry the railway over ravines on the west bank of the reservoir, and the Beacons site was reached, creating a railway that was 7.25 miles (11.67 km) in length. Puddle clay for

420-573: A report on all possible sources of water for Cardiff, so that they could plan for the future. Williams presented his reports in May and August 1881, suggesting that the best scheme was to impound the waters of the upper Taff Fawr. The Corporation were a little hesitant, but consulted the water engineer John Frederick Bateman , who also recommended the Taff Fawr scheme in June 1882 as the one most likely to meet

490-399: A single span of 55 feet (16.8 m) and a width of 14 feet (4.3 m). It carries a date plaque stating it was built in 1811, but that probably refers to an earlier wooden bridge, and the main arch was rebuilt in 1993. The river turns to the east to flow around the southern edge of Treharris , and then in a large loop around higher ground on which is Goitre-Coed. Three listed bridges cross

560-571: A span of 63 feet (19.2 m) and is one of the earliest railway bridges, but was in poor condition in 2002, as is the Victoria Bridge, which was also rebuilt in 1815. Continuing to the south-west, the river is crossed by the A472 and A470 roads, and at Abercynon is crossed by the B4275 road. Immediately to the south of the bridge was an aqueduct carrying the defunct Glamorganshire Canal over

630-472: A water level at 1,506 feet (459 m), it was one of a very small number of artificial lakes built above the 1,500-foot (457 m) contour. The dam had a small tower to the west, and a larger one to the east, below which a tunnel outlet built in Piranesi style sat at the base of the dam. Neuadd House, built as part of the reservoir project in 1896, is just downstream from the dam. An octagonal building at

700-505: A weir between them. Nant Rhyd-y-car joins on the west bank at Cae-draw, just before the A4102 crosses. As it approaches Abercanaid Industrial Estate, the railway from Merthyr Tydfil railway station joins the east bank of the river and runs parallel to it for much of its length. It curves around the eastern edge of Abercanaid , below which it is crossed by the A4060 road bridge. At Troed-y-rhiw

770-626: Is grade II* listed as its history and architecture surpass that of most other railway viaducts in Wales. On the west bank are the remains of a leat, constructed in 1766 for the Cyfarthfa Ironworks . It is fed by a stone weir with a cast iron sluice. Parts of the leat are cut into solid rock, and parts have stone walls and buttresses. The river is joined by the Taf Fechan near Cyfarthfa Castle . The Taf Fechan rises immediately to

840-422: Is 1,073 feet (327 m) Above Ordnance Datum . Unlike the other two reservoirs in the chain, the size as built was that specified by the original Act of 1884, whereas the capacity of Beacons and Llwyn-on was doubled when construction began. The remote location of Cantref Reservoir and the huge amount of material needed to construct the dam resulted in plans for a standard gauge railway to be built. This left

910-406: Is 92 feet (28 m) high and 420 feet (128 m) long. Just to the south of the viaduct is Pont-sarn, a stone bridge built in 1864 after the previous wooden one collapsed. This occurred because the parishes of Merthyr and Vaynor were supposed to maintain it jointly, but could not agree, and so it became dilapidated. There were proposals to widen it in 1955, but the plans were withdrawn when there

980-410: Is a large funnel with convex sides and concrete ribs. Both are grade II listed, together with the dam and a lattice steel bridge. The filter house, with its twelve rapid gravity filter beds, which have been little altered since 1923, is also listed, as are the turbine house, which controlled how much water flowed over the weir, and the compensation basin below that, which is used to regulate the flow in

1050-687: Is a river in Wales . It rises in the Brecon Beacons as two rivers, the Taf Fechan ("little Taff") and the Taf Fawr ("great Taff") before becoming one just north of Merthyr Tydfil . At Cardiff , it empties into the Bristol Channel . The river supports several species of migratory fish , including salmon , sewins (sea trout), and eels . From its confluence at Cefn-coed-y-cymmer, the river flows south, passing several towns. It picks up

1120-679: Is joined by the Afon Rhondda . From Pontypridd, it runs roughly south before arriving at the northern boundary of the city of Cardiff . In Cardiff, the natural course of the river was changed during the 19th century; from Cardiff Castle it now follows an artificial riverbed west of where it previously flowed, following a path through Bute Park , past the Cardiff Arms Park and the Principality Stadium . The Taff flows into Cardiff Bay , an artificial lake created by

1190-963: Is located in the Brecon Beacons National Park , mostly in the Powys unitary authority area and within the historic county boundaries of Breconshire . Part of the south west corner is in the Rhondda Cynon Taff unitary authority area. A public footpath crosses the dam and links with the Taff Trail and the Navvies Line paths. Cardiff Corporation had bought out the Cardiff Waterworks Company in 1879, and in March 1881 asked their Borough Engineer, John Avery Brandon Williams, to produce

1260-666: The Cefn Coed Viaduct , the Nant Ffrwd , a tributary that runs eastward in a deep wooded gorge before flowing into the Taf Fawr above the confluence with the Taf Fechan , emerges into the river from a deep, narrow gorge. The Taff continues south through the centre of Merthyr Tydfil , where it is joined by the Nant Morlais which emerges at Abermorlais from a culvert in the east bank. Just south of Merthyr weir,

1330-451: The London and North Western Railway / Brecon and Merthyr Tydfil Junction Railway joint line near Cefn-coed-y-cymmer station, and passed through a rocky gorge, where a trestle bridge was built to carry it over the Taff Fawr. The bridge was 150 feet (46 m) long, and some 50 feet (15 m) above the river. After that, it ran on a ledge to the west of the river, and by the time it reached

1400-767: The Nant Rhydycar joins. South of Merthyr, the Taff begins to meander its way between Pentrebach and Abercanaid and through Troed-y-rhiw , Merthyr Vale and Aberfan towards Quakers Yard . Here, the Taff Bargoed , Nant Mafon and then down into Abercynon in the Cynon Valley where the Afon Cynon merge with the Taff and, slightly further downstream the Nant Clydach joins. At Pontypridd it

1470-417: The 19th century fabric remains, and is thought to be the earliest multi-span railway bridge still in existence in the world. Two more modern road bridges are located on its south side, and further downstream is Castle Bridge, a narrow structure with three arches dating from the early 19th century. It formerly carried a road, but is now only used by pedestrians. Next there is a large, crescent-shaped weir, which

1540-721: The B4285 Bridge Street crosses, and the Afon Tâf High School if located on the east bank. A little further south, Ynysowen Community Primary School is on the west bank and the river curves around the eastern edge of Aberfan , part of the Merthyr Vale community. Below Aberfan, the river enters a wooded section, and the remains of the Merthyr Tramroad are sandwiched between the river and the modern railway. The Merthyr or Penydarren Tramroad

1610-531: The Corporation. Work began on it around April 1886, and it was largely finished by October, although storm damage meant that some of the ballasting was delayed. After Jones' reservoir contract had been revoked, the railway was valued at £3,395 in December 1888 as part of the settlement litigation. A temporary incline was constructed in June 1889 to the north of the dam, but it is not clear whether this began at

1680-751: The Taf Fechan Water Supply Board, uniting the Rhymney Valley Water Board, the Pontypridd and Rhondda Joint Water Board, the Urban District Councils of Aberdare and Llantrisant & Llantwit Fardre, and Merthyr Tydfil Corporation. The reservoir was opened by Lord Buckland of Bwlch on 21 July 1927. The valve tower is octagonal and built in Gothic style, with a copper-covered spire. The outflow

1750-543: The Taf Fechan below the reservoir. Below the works is Pont Sticill, a single span bridge with a datestone showing it was built in 1825, which gives its name to the village. Below Pontsticill the river forms the boundary of the Brecon Beacons National Park and descends into a wooded gorge, where it is crossed by the seven-arched Pontsarn Viaduct built for the Brecon and Merthyr Railway in 1866. It

1820-576: The Water Committee relieved him of his contract, paid for the work that had been done, and took possession of his plant, railways, a quarry and a clay field from which the puddle clay was extracted. Mackay's involvement with the project ceased on 13 June 1891. Completion of the reservoir was achieved by using direct labour. J T Jones was the first site manager, but became ill, and this role was taken over by F Orton in November 1881. The reservoir

1890-419: The balancing reservoirs at Blackbrook, Cefn and Rhubina for the Corporation. The contract was for £89,619, and he had two years to complete the work, but again progress was slow, with the extremely wet weather of 1890 being a significant factor. He struggled to retain his workforce, and wrote to J A B Williams explaining the difficulties. By February 1891 he had completed about half of the job, and on 18 March 1891

1960-456: The chain, did not start until 1911, and again, its capacity was increased by an Act obtained in 1909 to 1,260 million imperial gallons (5,700 Ml), almost double that specified in 1884. Impounding of water began on 23 June 1926, and the reservoir was full by November, but formal commissioning did not take place until May 1927. Once built, it supplied 7.75 million imperial gallons (35.2 Ml) of compensation water per day to maintain

2030-637: The construction of the Cardiff Bay Barrage in the 1990s, before flowing into the Severn Estuary . 51°28′N 3°11′W  /  51.467°N 3.183°W  / 51.467; -3.183 Cantref Reservoir Cantref Reservoir is the middle of the three reservoirs in the Taff Fawr valley in Wales . It was built by Cardiff Corporation Waterworks between 1886 and 1892, but since 1973 has been owned by Welsh Water . It

2100-524: The construction of the core of the dam was obtained from land owned by the Crawshay Brothers, part of their ironworks near Merthyr Tydfil . It was located near the Six Bells public house at Pen-yr-Heolgerrig, and a 3 ft ( 914 mm )-gauge railway was used to transfer the clay from the field to the main line railway. It was then moved to the Corporation sidings at Cefn Coed, from where

2170-568: The east in a large bend. The A4058 dual carriageway crosses the bend at an angle, and as the river resumes its southward course, it is crossed by Machine Bridge, which is also known as Pont y Doctor, as it was built by Dr Richard Griffiths in 1809, as part of a tramway to carry coal from the Hafod Uchaf pit to the Glamorganshire Canal. It has three arches, and was widened around 1910, in an early use of reinforced concrete. Some of

2240-527: The east side of the Lower Neuadd dam is also a listed structure. The river continues southwards through a steep-sided wooded valley and is crossed by Pont Cwmyfedwen, an early- to mid-19th century single span bridge before it reaches Pentwyn Reservoir , the oldest of the four reservoirs. It was built by the Merthyr Board of Health between 1859 and February 1863, and the consulting engineer for

2310-406: The flow in the Taf Fawr, and working on the upper area first meant that the Corporation only had to supply 3 million imperial gallons (14 Ml) per day of compensation flow until work started on the lower area. Cantref Reservoir , the lower of the two in the upper area, was constructed first. Work began on 4 May 1886 and was completed on 14 September 1892. Construction of Beacons Reservoir ,

2380-461: The flow in the Taff Fawr, and working on the upper area first meant that they only had to supply 3 million imperial gallons (14 Ml) per day of compensation flow until work started on the lower area. Cantref Reservoir, at the time known as Cantreff, was the first to be built, together with a 32-mile (51 km) pipeline to Lisvane Reservoir and Llanishen Reservoir and intermediate balancing reservoirs at Blackbrook, Cefn, and Rhubina. Work on

2450-664: The flow in the river. Below Llwyn-on, the river is crossed by the A470 Brecon to Merthyr road , the A465 Heads of the Valleys road , and as it passes to the south-west of Cefn-coed-y-cymmer , the Cefn Railway Viaduct. which consists of 15 arches built on a curve. It was to have been built of stone, but a masons strike in 1866 resulted in the Brecon and Merthyr Railway buying 800,000 bricks to complete it. It

2520-403: The highest in the chain, began shortly afterwards, in April 1893, in advance of the Corporation obtaining a second Act of Parliament to increase the capacity of the reservoir and to move the dam further upstream, where the foundations would be better, in the light of geological investigation. Impounding of the water began on 17 September 1897. Construction of Llwyn-on Reservoir , the third in

2590-494: The history of the standard gauge locomotives used on the construction project is a little more difficult. Jones, the first contractor, is known to have had one locomotive, and possibly a second. When Mackay took over the contract, he bought four more with him, and so there were five or six operating during this period. The Corporation bought a second-hand locomotive in 1891, and two new ones in 1891 and 1894. Four 0-6-0 and two 0-4-0 saddle tanks have been positively identified, and there

2660-509: The job, and progress became very slow. The Town Clerk took possession of the works on 29 October 1888, which included Jones' plant, tools and implements. Jones then took out a writ against the Corporation, and an agreement was not reached until June 1889, with the Corporation paying £10,000 to the court in July. Meanwhile, a new contract was awarded in March 1889 to John Mackay of Newport, who had previously completed work on Llanishen Reservoir and

2730-467: The loop. The first was built by Isambard Kingdom Brunel in 1840–41, and consists of six arches on a slight curve. It carried the single track Taff Vale Railway , but was doubled in width within 20 years, to enable it to carry twin tracks. The second was part of the Merthyr Tramroad, and was built in 1815 after the original wooden bridge collapsed into the river when a train crossed it. It has

2800-447: The lower level and was used to raise materials, or began at the higher level and was used to lower them to the worksite. The railway was built on land owned by Sir William Lewis to the south of Cantref, and was later extended northwards over land belonging to Lord Tredegar to enable the reservoir at Beacons to be built. In 1891 the Corporation negotiated with Lewis to allow the railway to remain in place for another six years, and it

2870-554: The main route of the Taff was around Cardiff Castle and down what is now Westgate Street , with the lands where Cardiff Arms Park and the Millennium Stadium are now sited tidal flats which were prone to flood. Isambard Kingdom Brunel 's solution was to divert the Taff to the west, creating a larger and safer site for the station. The station was opened by the South Wales Railway in 1850. Underneath

2940-511: The meteorologist George James Symonds also gave evidence, and although it cost the Corporation £3,652 to fight the case, Royal Assent was obtained for the Cardiff Corporation Act 1884 on 7 August. The catchment of the upper Taff Fawr was 10,400 acres (42 km ) but it was split into an upper area of 4,000 acres (16 km ) and a lower one of 6,400 acres (26 km ). Any works had to provide compensation water to maintain

3010-481: The mouth of the River Ely . The Taf Fawr rises below the peak of Corn Du , south-west of Pen y Fan and soon flows in a generally southerly direction through a steep-sided valley, which was identified by Cardiff's Borough Engineer John Avery Brandon Williams as the best source of water for the town when he assessed all possible sources of water for the newly formed Cardiff Corporation Waterworks in 1881. A bill

3080-442: The needs for water at the lowest cost. They presented a bill to Parliament in November 1883, which was considered by a House of Commons Committee between 1 May and 20 May 1884. There were 16 petitions against it and serious opposition from riparian landowners, but several influential civil engineers was called to give evidence, notably Bateman, Thomas Hawksley James Mansergh, and George H. Hill. J A B Williams, their own Engineer, and

3150-469: The pipeline was completed in September 1888, and on the balancing reservoirs in November 1888. Construction or the reservoir was not so straight forward. Initially the contract for construction of the earth dam, which was about 600 feet (180 m) long with a puddle clay core, was awarded to William Jones of Neath. To provide access to the site, a standard gauge railway, some 6 miles (9.7 km) long,

3220-536: The private locomotives hauled it up the valley to Cantref. One narrow gauge locomotive is known to have worked at the clay pit, an 0-4-0 saddle tank named Darrell , which was obtained second-hand from the Bargoed Coal Company of Fochriw around 1885. It was probably obtained by Mackay, but passed into Corporation ownership when his contract was terminated, and was sold to the Crawshay Brothers in early 1897 for £150, becoming their Cyfarthfa 14 . Tracing

3290-523: The project was Thomas Hawksley , but despite this, the dam was built over a geological fault, which led to large volumes of leakage. This leakage was one of the main factors that led to the construction of the Lower Neuadd Reservoir. Remedial work was carried out at regular intervals, but never seemed to last for long. Repairs undertaken in 1912/13 reduced the level of leakage from 11 to 2 million imperial gallons (50 to 9 Ml) which

3360-561: The rest of the stone was obtained from a quarry near Cefn Coed, served by sidings on the railway, at which extraction began while Jones was fulfilling his contract. As built, the crest of the dam was 120 feet (37 m) above the foundations, and 90 feet (27 m) above the level of the river. At its maximum, the water is 73 feet (22 m) deep, and the dam created a reservoir which is 0.75 miles (1.21 km) long, holding 323 million imperial gallons (1,470 Ml). It covers an area of 42.85 acres (17.34 ha) and its surface level

3430-490: The river from the Pontsticill Water Treatment Works, which United Utilities operate on behalf of Dwr Cymru Welsh Water . The pollution turned the water white for at least 3 miles (5 km) downstream of the works and killed approximately 23,000 fish, including wild brown trout, bullheads , stickleback and pike , and a large number of invertebrates. Environment Agency Wales estimated that

3500-492: The river would take six to twelve years to recover. The trout population had resumed breeding by 2009. Just below the confluence of the Taf Fawr and Taf Fechan, the river is crossed by the Pont-y-Cafnau tramroad bridge. This was probably the first iron railway bridge to be built, and was unusual in that it had three levels. The main deck carried the 4 ft ( 1,219 mm )-gauge Gurnos Tramway, beneath which there

3570-405: The river. The Afon Cynon joins on the right bank, and close to the junction is spanned by a skewed railway bridge with two arches of unequal sizes. The valley then widens, and the river begins to meander. On the northern edge of Glyncoch , the river is joined by the Nant Clydach on its right bank, and to the south of the settlement is crossed by a three-bay girder viaduct, built in 1885 to carry

3640-416: The site of Llwyn-on Reservoir , on which work did not start until 1911, it ran along the valley floor. At first, it may have crossed over the river near Nant-Ddu lodge, and run along its eastern bank to the foot of the dam, but it later stayed on the western bank to reach the top of the dam. The track was built by William Jones, the first contractor for the reservoir, on the basis that it would be taken over by

3710-491: The south of Pen y Fan and runs southwards through three reservoirs and a former fourth, now abandoned. Whereas the Taf Fawr was the preserve of Cardiff Corporation, the Taf Fechan was used to supply water to Merthyr Tydfil Corporation. Of the Upper Neuadd and Lower Neuadd reservoirs, the lower one was built first, authorised by an Act of Parliament obtained in 1876. Like those on the Taf Fawr, it had an earth embankment with

3850-470: The valley floor, and the reservoir was designed to hold 3,290 million imperial gallons (15,000 Ml), although this was subsequently increased a little by raising the water level by 12 feet (3.7 m). Completion was delayed by the onset of the First World War, and when work resumed in 1922, the Corporation used direct labour. The Taf Fechan Water Supply Act had been passed in 1921, creating

3920-492: The weir, including a casting house, a workshop, a tinning house, a smithy, a rolling mill, and the retaining wall for the leat. The leat had seven sluices with gates to feed the works, but all have been bricked up. In the early 1840s the South Wales Railway was trying to find a suitable site for a railway station, but the area that is now Cardiff Central railway station was prone to flooding. At this point

3990-531: The world in its heyday. The river runs through the western edges of Merthyr Tydfil , where it is crossed by modern bridges carrying the A4054 and A4102 roads, and by Jackson's Bridge, an early 19th century single span structure that carried the Dowlais tramway and a road. Two modern bridges in central Merthyr Tydfil carry the northbound carriageway of the A4054 across the river to its west bank and back again, with

4060-408: Was agreed, providing that the route was properly fenced, gates were provided at level crossings where necessary, and goods for local farms could be transported from Cefn for free. When the railway was no longer needed, the land would be reinstated, or the landowner could buy it. However, around 1.04 miles (1.67 km) of track were lifted in March 1892, after a disagreement developed. This was probably

4130-471: Was an iron trough to carry water from the Taf Fechan leat, while a second water supply was carried in a wooden launder above the tramway tracks. The cast iron structure was manufactured at the Cyfarthfa Ironworks. On the west bank of the river are the remains of the ironworks, which began operating in 1765. The artifacts include seven blast furnaces, which formed part of the largest ironworks in

4200-461: Was built from Cefn Coed to the reservoir sites, and by the time the first sod was cut for the reservoir by the Mayor on 4 May 1886, around 2 miles (3.2 km) of the railway had already been completed. Jones succeeded in cutting the embankment trench and filling the bottom with a concrete key, but he lacked funds, and did not have enough pumping plant to keep the workings dry. Many of his labourers left

4270-432: Was built in 1793, and was the scene of the first passenger carrying train journey in the world, when Richard Trevithick 's high pressure steam locomotive pulled wagons containing 5 tons of iron ore and seventy passengers in 1804. The tramway ceased operation around 1880, and this section, which is a scheduled monument, is particularly well preserved. The river is crossed by an old farm access bridge at Pont y Gwaith, with

4340-459: Was built in 1834–5 to provide water power to the Treforest tinplate works . The sluice to control the flow of water to the works is at the western end of the weir, and probably dates from a little later. The works continued in operation until 1939, and a fish ladder was added in 2003, to allow migrating fish to access the upper river. Many of the building still exist, some distance to the south of

4410-532: Was constructed in 1825. Its main function was to provide the ironworks with a good supply of water, but it also fed the ornamental lake at Cyfarthfa Castle through a syphon. After passing under the A465 and the A4054 roads, the Taf Fechan merges with the Taf Fawr at the wooded confluence that gives Cefn-coed-y-cymmer its name. The river holds a large population of wild brown trout , many of which were killed in 2006 when three tonnes of aluminium sulphate spilled into

4480-401: Was constructed. The next crossing is Pontypridd Bridge, a high-arched single span of 140 feet (43 m). It was built in 1756 by an Independent minister and self-taught civil engineer called William Edwards, and was his third attempt, after his two earlier bridges collapsed. It features three round openings in its spandrels, a device he used to relieve the pressure on an unusually wide arch. It

4550-559: Was formally opened on 14 September 1892 by Alderman David Jones, who was chairman of the Waterworks Committee, and impounding of water began on the same day. A plaque to commemorate the event named the Waterworks Engineer, J A B Williams, but failed to mention either of the contractors. The weir and the steps of the overflow channel on the western side of the dam were faced in granite obtained from Cornwall, but

4620-469: Was presented to Parliament in November 1883, and despite serious opposition from riparian landowners, Royal Assent was obtained for the Cardiff Corporation Act 1884 on 7 August. It allowed the corporation to build three reservoirs. The catchment of the upper Taf Fawr was 10,400 acres (42 km ) but it was split into an upper area of 4,000 acres (16 km ) and a lower one of 6,400 acres (26 km ). Any works had to provide compensation water to maintain
