The Belfast Water Commissioners was a public body in Ireland and later Northern Ireland, [N 1] established by the Belfast Water Act 1840, to improve the supply of water to the expanding city of Belfast. By 1852, the city was suffering a shortfall in supply of almost one million gallons per day. [1] [2] In 1889 the body's name was changed to Belfast City and District Water Commissioners in recognition of the expanding boundaries of Belfast and resulting increased demand for water.
Major infrastructure completed for the Belfast City and District Water Commissioners includes the Mourne Conduit, the Mourne Wall, Silent Valley Reservoir, the Binnian Tunnel and Ben Crom Reservoir.
The Water Commissioners' responsibilities were transferred to the Department of the Environment's Water Executive in 1974 and are now managed by Northern Ireland Water.
The Belfast Water Commissioners was a public body established by the Belfast Water Act 1840, to improve the supply of water to the expanding city of Belfast. By 1852, the city was suffering a shortfall in supply of almost one million gallons per day. [1]
In 1889, the expansion of Belfast's boundaries and increased demand for water lead to the change of name to Belfast City and District Water Commissioners or BC&DWC. [3]
In 1891, the Commissioners appointed local civil engineer, Luke Livingston Macassey to identify water resources to sustain Belfast. [4] Macassey ruled out Lough Neagh which, as the largest lake in the British Isles, would have been an abundant source of water, however water quality was a concern and its altitude meant that water would have to be pumped to Belfast. [5] Other sources in County Down, and County Antrim were rejected: [6]
Macassey ultimately selected the Mourne Mountains in Down. Upon deciding on the site, the Water Commissioners acquired a 9,000-acre (3,600 ha) catchment area; Private Acts of Parliament (in 1893, 1897 and 1899) allowed the purchase of the Mournes land and related access permits and water rights. [4] At the time the catchment was capable of providing some 30 million imperial gallons (140,000 m3) of water per day, however because this was more than was required at that point, a three phase scheme was developed.
The first stage was to divert water from the Kilkeel and Annalong rivers through the Mourne Conduit to a reservoir near Carryduff. These water pipes and tunnels were capable of supplying 10 million imperial gallons (45,000 m3) of water per day. Work was completed in 1901. [4] The second stage was to build a storage reservoir, the Silent Valley Reservoir across the Kilkeel River, to supply another 10 million imperial gallons (45,000 m3) of water per day. Design work on this phase began in 1910, but procurement of the work was delayed by World War I. A contract was eventually awarded in 1923 to S. Pearson & Son and work continued until 1933. [7]
The commissioners were responsible for the construction of the Mourne Wall which encloses the catchment area. Northern Ireland Water began to restore in this structure in 2017. [8]
In 1938, the commissioners purchased a building now known as the Water Office due to the need for more office space. [9] [10] [11] It was purchased by Marks & Spencer in 1983 and became part of its extended city centre store. [12]
The Irish Boundary Commission was established in 1924 to decide on the delineation of the border between the Irish Free State and Northern Ireland. The BC&DWC made representations to that body, objecting to any movement of the border north from the existing County Down boundary on the following grounds: [13]
The border was ultimately unchanged, leaving the Mourne catchment area and water infrastructure within Northern Ireland.
The powers vested in the Belfast City and District Water Commissioners were transferred to the Minister of Development on 1 October 1973. Provision of water and sewerage services became the responsibility of the Water Service by 1 January 1974, itself a division of the Department of the Environment. [3] In 1996, the Water Executive became an executive agency and was rebranded as the Northern Ireland Water Service and, in 1999, responsibility for water transferred to the Department for Regional Development. The Northern Ireland Water Service became Northern Ireland Water in April 2007.
County Down is one of the six counties of Northern Ireland, one of the nine counties of Ulster and one of the traditional thirty-two counties of Ireland. It covers an area of 961 sq mi (2,490 km2) and has a population of 552,261. It borders County Antrim to the north, the Irish Sea to the east, County Armagh to the west, and County Louth across Carlingford Lough to the southwest.
Newry and Mourne District Council was a local council in Northern Ireland. It merged with Down District Council in May 2015 under local government reorganisation in Northern Ireland to become Newry, Mourne and Down District Council.
The Mourne Mountains, also called the Mournes or Mountains of Mourne, are a granite mountain range in County Down in the south-east of Northern Ireland. They include the highest mountains in Northern Ireland, the highest of which is Slieve Donard at 850 m (2,790 ft). The Mournes are designated an Area of Outstanding Natural Beauty and it has been proposed to make the area Northern Ireland's first national park. The area is partly owned by the National Trust and sees many visitors every year. The Mourne Wall crosses fifteen of the summits and was built to enclose the catchment basin of the Silent Valley and Ben Crom reservoirs.
South Down is a parliamentary constituency in the United Kingdom House of Commons. The current MP for the constituency is Chris Hazzard of Sinn Féin.
Carryduff is a small town and townland in County Down, Northern Ireland, about 10 kilometres (6.2 mi) south of Belfast city centre. It had a population of 7,173 people in the 2021 Census. Most of the settlement lies within the townland of Carryduff, although part of it extends into the neighbouring townlands of Killynure and Mealough.
Silent Valley may refer to:
Annalong is a seaside village in County Down, Northern Ireland at the foot of the Mourne Mountains. Annalong is in the civil parish of Kilkeel, the barony of Mourne, and the Newry and Mourne District Council area. It had a population of 1,805 at the 2011 Census. The village formerly exported dressed granite and is now a fishing and holiday resort.
The Silent Valley Reservoir is a reservoir located in the Mourne Mountains near Kilkeel, County Down in Northern Ireland. It supplies most of the water for County Down, surrounding counties and most of Belfast. It is owned and maintained by Northern Ireland Water Limited. The reservoir was built between 1923 and 1933 by a workforce of over 1,000 men, nine of whom died during construction.
The Mourne Wall was constructed to enclose a catchment area of the Silent Valley Reservoir in the Mourne Mountains, Northern Ireland. The 1.5 metres high stone wall, which was built to keep livestock from contaminating water supplies, took almost twenty years to complete. The project was overseen by the Belfast City and District Water Commissioners.
The Metropolitan Water Board was a municipal body formed in 1903 to manage the water supply in London, UK. The members of the board were nominated by the local authorities within its area of supply. In 1904 it took over the water supply functions from the eight private water companies which had previously supplied water to residents of London. The board oversaw a significant expansion of London's water supply infrastructure, building several new reservoirs and water treatment works.
Northern Ireland Water Limited is the main water company in Northern Ireland.
Slieve Binnian is one of the Mourne Mountains in County Down, Northern Ireland, 9 km north of Kilkeel. It is the third-highest mountain in Northern Ireland at 747 metres (2,451 ft). The summit is broad and flat with rocky tors at the north and south ends, with the Back Castles, impressive towers of granite, in between. To the south-west is Wee Binnian (460m). It lies east of Silent Valley Reservoir and west of the Annalong Valley. The Mourne Wall also crosses over Slieve Binnian.
The Local Government (Boundaries) Act 1971 was an Act of the Parliament of Northern Ireland, passed in 1971 to replace the previous system of local authorities established by the Local Government (Ireland) Act 1898. The system was based on the recommendations of the Macrory Report, of June 1970, which presupposed the continued existence of the Government of Northern Ireland to act as a regional-level authority.
Spelga Reservoir is a reservoir in the townland of Spelga in the Mourne Mountains of County Down, Northern Ireland. It was formed by the Spelga Dam and sits at over 1,200 ft (370 m) above sea level. It has a volume of 2,700,000 cubic metres and a catchment area of 5.423 km². It occupies an area known as Deers Meadow, and impounds the River Bann, which rises on the nearby Slieve Muck.
The Portland Water Bureau is the municipal water department for the city of Portland in the U.S. state of Oregon. The bureau manages a water supply that comes mainly from the Bull Run River in the foothills of the Cascade Range east of the city and secondarily from the Columbia South Shore Well Field near the Columbia River. As of 2023, Mingus Mapps was the city commissioner in charge of the bureau, and the chief administrator is Michael Stuhr. Budgeted departmental revenues for fiscal year 2015–16 included about $157 million for charges for services.
Luke Livingstone Macassey was an Irish civil engineer and barrister, notable for his contributions to public health by improving the water supply in the north of Ireland. In 1874 he was appointed consultant hydraulic engineer by the Belfast Water Commissioners in which capacity he was instrumental in finding new sources of water for the expanding city of Belfast. He proposed use of a 9,000-acre catchment area in the Mourne Mountains and a three stage project:
Ben Crom Reservoir is a reservoir located in the Mourne Mountains near Kilkeel, County Down, Northern Ireland. Along with Silent Valley Reservoir, which is situated further down the Kilkeel River valley, it supplies water for County Down, surrounding counties and most of Belfast. It was constructed between 1953 and 1957, as the final part of the Mourne scheme to provide water to Belfast which started with the passing of the Belfast Water Act in 1893.
The Mourne Conduit was a water main which ran 42 kilometres (26 mi) from the Silent Valley Reservoir to Carryduff, near Belfast and was built between 1893 and 1901 for the Belfast City and District Water Commissioners. This was supplemented by additional pipelines twice in the 20th Century. This system supplied water to Greater Belfast and North Down for more than 100 years. It is labelled as the Mourne Aqueduct in Ordnance Survey maps from the early 20th century.
