Grand Canal

Grand Canal

The Grand Canal in Dublin, Ireland, stands as a testament to the city’s rich industrial heritage and ambitious engineering endeavours. Spanning approximately 131 kilometers from Dublin to the River Shannon, the canal has played a pivotal role in Dublin’s development, transforming the city’s transportation, economy, and urban landscape.

Conceived in the late 18th century, the Grand Canal was designed to enhance trade and transport between Dublin and the central regions of Ireland. The project began in 1790 under the direction of engineer John O’Connell and was completed in 1804. It was a monumental undertaking aimed at creating a navigable water route that would facilitate the movement of goods such as coal, grain, and timber, which were vital for Dublin’s growing industrial sector.

The Grand Canal was constructed using advanced engineering techniques of its time. It featured a series of locks and aqueducts to manage the water levels and overcome Ireland’s varied topography. Notably, the canal included several impressive structures, such as the 24-lock system, which allowed boats to traverse the canal’s varying elevations, and the famed 45-meter-high Lucan Aqueduct, which carried the canal over the River Liffey. In its prime, the Grand Canal was a crucial artery for trade, connecting Dublin with the Shannon River and opening up new markets. It supported the city’s burgeoning industries, including brewing, milling, and manufacturing. The canal’s importance was reflected in its busy traffic, which included not just commercial barges but also passenger boats.

However, with the advent of railways and motor transport in the 19th and early 20th centuries, the canal’s commercial significance waned. The rise of more efficient transport modes led to a decline in canal traffic, and parts of the canal system fell into disrepair.

Despite its decline, the Grand Canal has undergone various restoration efforts in recent decades. Recognised for its historical value and scenic beauty, parts of the canal have been revitalized for recreational use. The canal now serves as a picturesque route for walking, cycling, and boating, attracting both locals and tourists. Its towpaths and scenic stretches offer a tranquil escape from the hustle and bustle of urban life.

The Grand Canal is more than just a historical artifact; it has become an integral part of Dublin’s cultural and environmental landscape. The canal supports diverse wildlife and provides a green corridor through the city. It also hosts various cultural events and activities, reflecting Dublin’s appreciation for its heritage.

Looking ahead, the Grand Canal continues to be a focal point for urban planning and development in Dublin. Initiatives aimed at preserving and enhancing the canal’s infrastructure are ongoing, ensuring that this historic waterway remains a vibrant part of Dublin’s urban fabric.

Association with Poddle

The Poddle River and two of it’s streams (Abbey and Tenter) flow under the Grand Canal.  The Poddle River, once vital for Dublin’s water supply and industry, had a significant association with the Grand Canal over time. In medieval Dublin, the Poddle flowed into the Liffey, supporting local industries and providing water for the city. However, as Dublin expanded, the Poddle’s role diminished, particularly with the introduction of the Vartry system in 1867, which improved water infrastructure.

By the 20th century, the Poddle faced challenges, including frequent flooding and inadequate sewer systems. To address these issues, Dublin’s sewerage improvements included plans to divert the Poddle and upgrade the Grand Canal’s infrastructure. Projects aimed to integrate the Poddle’s drainage into the Grand Canal’s system, improving sanitation and flood control across Dublin. These efforts reflected the evolving relationship between the Poddle and the Grand Canal, highlighting their intertwined roles in Dublin’s urban development.

What the Newspapers Say

  • Dublin’s historical sewer system was inadequate, with insufficient sewers causing pollution and flooding, particularly from the Poddle River and areas like Stephen’s Green and the Grand Canal. Despite Dublin’s overall good health, major improvements were delayed due to high costs. The Poddle River was a significant sewer on the south side, draining a large area but often flooding after heavy rains. Engineers proposed expanding and improving the sewer network, estimating costs at £80,029. This plan included building new sewers and repairing existing ones, with a focus on preventing floods and ensuring better sanitation across the city.
  • A woman attempted a heinous crime in Dublin, luring a four-year-old girl from Pill Lane to the “Back of the Pipes” near the Grand Canal Harbour. She stripped the child of her clothes and threw her into the nearby Poddle River, intending to drown her to cover her theft. The Poddle, often swift and dangerous, flows through the city into the Liffey. Fortunately, the girl survived, her cries attracting a nearby man who rescued her. The police later found the child’s clothes pawned, revealing the crime was motivated by greed. Authorities pursued the culprit.
  • In May 1900, the Public Health Committee in Dublin, led by Medical Superintendent Charles A. Cameron, reviewed various issues. They examined letters concerning improvement works at Coadys Cottages and Jane’s Ville, as well as cleansing operations at Marrowbone Lane. The Grand Canal Company addressed road maintenance along the Canal bank from Forbes’ Lane to Rialto Bridge. Reports included legal procedures for taking over private streets, painting Tara Street Baths, and concerns about Granby Place. A subcommittee also investigated the proposal to divert the Poddle River, highlighting ongoing public health and infrastructure concerns in Dublin.
  • In response to unemployment, the Dublin Borough Commissioners initiated a £45,000 government-funded project, focusing on essential infrastructure. In Crumlin, sewerage system excavation began to support housing developments. The construction of settling tanks at the Grand Canal’s 5th and 8th Locks aimed to improve water supply for brewers and distillers. A new sewer was planned for Drumcondra and Glasnevin due to increased demand. The Poddle River was diverted to prevent its water from entering sewers, including covering a watercourse near a tobacco factory and church. Negotiations also occurred for canal bank road improvements, extending from Parnell Bridge to Dolphin’s Barn Bridge.
  • In the past, Dublin’s water supply came from the Dodder River, supplemented by the Poddle stream, which originated in Tymon. The Poddle was vital for industries and water mills in the Liberties. Despite improvements like new mains and reservoirs, early systems faced issues, such as leaks and financial burdens on citizens. The Domville family, who controlled water passing through their Templeogue lands, occasionally cut off the city’s supply. Relief came in 1775 when the Grand Canal began providing water. The Poddle’s role diminished over time, especially after the Vartry system was introduced in 1867, improving Dublin’s water infrastructure.
  • In November 1787, severe weather caused chaos in Dublin, with rivers like the Bradogue, Dodder, and Poddle overflowing. The Poddle’s flooding forced residents from New Street to Bride’s Alley and beyond, seeking refuge on rooftops. Meanwhile, construction projects continued, such as new bridges over the Liffey and plans for a dock near the Custom House. Despite the devastation, the Grand Canal’s engineers were praised for safeguarding the canal between Dublin and Monasterevin. The widespread flooding and strange weather events, including the Lisbon earthquake, made Dublin’s calmer days seem fortunate in comparison.
  • Late on Thursday night, the River Poddle caused severe flooding in Rutland Avenue when it became choked where it runs underground at Dolphin’s Barn. Water rose to three feet inside cottages, forcing some residents to evacuate and others to spend the night bailing out water. The flooding was blamed on a clogged grating just above Rutland Cottages, where the Poddle flows underground for 400 yards before discharging into the Grand Canal near Dolphin’s Barn Bridge. Mrs. McNamara of Rutland Cottages described the ordeal of keeping her children safe as water flooded their home. Other residents also reported extensive damage.
  • In September 1938, it was noted that George Bernard Shaw’s father, George Carr Shaw, had once operated a mill at Dolphin’s Barn, Dublin. The mill was located on what was formerly Hall’s Lane, now Rutland Avenue, near the south bank of the Grand Canal. The mill used water from the Poddle, which was diverted from “The Tongue” at Kimmage. The original mill site, referred to as “Shaw’s Mill,” still had visible ruins. Shaw’s father was known to have been a miller in that area, and local accounts recalled Shaw’s involvement in the neighborhood as a child.
  • In the past, Dublin’s water supply was managed in a way that reflected the city’s long history. The old Blessington Basin, fed by the Royal Canal, had been used to provide low-pressure water to the north side of the city and some dock areas. The Poddle was diverted into a reservoir behind the convent at the Grand Canal Harbour on James Street, known as “The Back of the Pipes.” This setup supplied water to the area between the South Circular Road and the Liffey. Despite modern updates, remnants of the old system, like iron-handled pumps, were still found in older houses.
  • Dublin Corporation, led by Minister for Local Government Mr. Blaney, considered legislation to close a 5-mile stretch of the Grand Canal from Blackhorse Bridge to Ringsend for drainage. The Streets Committee reviewed a report from the assistant city manager, B. O’Brolchain, which proposed two schemes: a “city only” plan costing £1,008,400, including a foul sewer along the canal and surface water pipes, and a “city and county” scheme costing £1,262,000. This combined scheme would also cover 3,830 acres in the county. The plan also included the culverting of the River Poddle from Kimmage Manor.
  • In a letter to the editor dated November 15, 1963, Noel T. Lemass responded to W. A. Newman’s suggestion to purify the Grand Canal. Lemass questioned whether Newman also supported purifying dangerous quarries and the rivers Camac and Poddle. He noted that legislation was underway to improve road safety and address other hazards, including culverting the Camac and Poddle. Lemass criticised Newman’s approach, arguing that focusing on purifying the canal might exacerbate traffic congestion. He suggested that reclaiming the canal could help alleviate traffic issues and expressed skepticism about Newman’s proposals, emphasisng a more practical perspective.
  • At a special Dublin City Council meeting, City Manager Mr. M. Macken discussed potential joint proposals with Dublin County Council to address flooding. He outlined plans for a combined engineers’ report. City Engineer Mr. E. J. Burke noted that flooding issues, including those from the Grand Canal and the Poddle, were complex and often fell outside the city’s jurisdiction. Despite spending £65,000 on drainage and proposing a flood plain on Anglesea Road, Burke criticized the economic feasibility of extensive flood defenses. He highlighted the Poddle’s inadequate capacity during recent floods and suggested future plans to divert excess water to the Tolka to prevent further flooding.
  • On January 6, 1839, the Great Windstorm ravaged Ireland, leaving devastation across Dublin. The gale, known as “The Night of the Big Wind,” caused widespread damage: roofs were ripped off, buildings collapsed, and flooding ensued. The storm particularly affected the Grand Canal and the Poddle. Trees were uprooted from the Grand Canal’s banks, and a boat capsized in Portobello Harbour. The Poddle’s capacity was overwhelmed, exacerbating the flooding. The tempest also tore through streets like Sackville (O’Connell) Street, causing numerous fatalities and injuries. The city witnessed both tragic losses and miraculous escapes amid the chaos.
  • In July 1961, Dublin Corporation’s Streets Committee recommended using the Grand Canal’s line for a new interceptor sewer from Blackhorse Bridge to Ringsend Outfall and a surface water drain to the Liffey at Grand Canal Dock. By October 1963, the City Engineer proposed converting the Grand Canal into an underground culvert with a sewer alongside, also including the long-overdue culverting of the Poddle. This plan required closing the canal through the city but promised not to disrupt navigation west of Inchicore. The Committee approved these plans and sought legislation for the canal’s closure and the implementation of the proposed changes.
  • In a meeting at UCD, Dublin’s Assistant City Manager, Mr. Ruari O’Brolchain, assured that the Grand Canal would reopen after sewage pipes were laid along its bed. Despite these assurances, many societies dedicated to the canal’s preservation remained skeptical. Mr. O’Brolchain argued against estimating the cost of alternative routes for sewage pipes, emphasizing that the drainage scheme was driven by housing and employment needs in areas like Terenure and Walkinstown. The increased runoff from these developments had overwhelmed the sewers, causing overflow into the Rivers Poddle and Swan.
  • The Department of Local Government was to be asked to approve a £35,000 Dublin Corporation scheme to address frequent flooding along the Poddle River during heavy rain. Assistant City Manager Mr. F. Feely informed Commissioner Mr. Garvin that it would be necessary to eventually culvert the entire 1,000-meter stretch from south of Kimmage Manor to the Grand Canal. The immediate concern was a 240-meter section from Greenmount Lane to the Grand Canal, which Mr. Feely noted was structurally weak and at risk of collapse at various points.
  • The foul state of the River Liffey, often joked about by Dubliners, was set to improve with the nearing completion of the multi-million-pound Dublin sewerage scheme. This joint project by Dublin Corporation and County Council, conceived in the mid-1960s, aimed to alleviate the burden on the old sewage system. The Grand Canal Tunnel, the project’s centerpiece, ran from Inchicore to Maquay Bridge and connected to a pumping station in Ringsend. This new system, designed to handle both foul and surface waste, was expected to dramatically enhance Dublin Bay’s condition. The scheme also addressed pollution from the Poddle, Dodder, Tolka, and other rivers.
  • A thousand years ago, Dublin was a bustling Viking port, connected by trade routes to Newfoundland, Constantinople, and Russia. The city, primarily on the south side of the River Liffey, featured the Poddle River, which widened into the Linn Dubh or “black pool,” providing anchorage for Viking longships. By 988, Dublin was a thriving settlement with timber houses and a wooden city wall. Over centuries, the Poddle became crucial for medieval water supply, but as the city expanded, its water needs grew. In 1244, Dublin rerouted water from the Dodder into the Poddle using a man-made canal, which served the city until 1775.
