Plug gets pulled on Pontcysyllte Aqueduct

5th Nov 2009

One of the most spectacular constructions in Wales is being upgraded in the wake of its elevation to World Heritage Status.

The 1007 foot long iron trough lining of Pontcysyllte Aqueduct is being drained and cleaned next week ahead of next year’s visitor season, which elevates Thomas Telford’s 204 year-old masterpiece to the status of legendary sites like the Statue of Liberty, the Taj Mahal and the Acropolis.

The iconic structure was last drained in November 2003, ahead of its 200th birthday celebrations in 2005. On that occasion, a full paint system was applied to protect the metalwork from rusting. The towpath was refurbished and an all weather surface applied.

The pulling of the plug

This dewatering will allow a thorough four day inspection of the structure to take place. The aqueduct is drained by the removal of a large plug located in the middle of the structure. When released, it sends a huge torrent of water cascading into the River Dee almost 130 feet below. The aqueduct holds 1.5 million litres of water and takes around two hours to drain.

The ceremonial pulling of the plug will be undertaken by a pupil from Ysgol Bryn Collen primary school in Llangollen, which was selected in a competition.

The aqueduct has long held a special place in the affection of the communities which live along the Llangollen Canal. Now, a dedicated community project is ensuring local people make a lasting contribution to the future of this wonderful monument.

'Pontcysyllte Aqueduct & Canal Project' is an ambitious partnership of British Waterways, Northern Marches Cymru, Wrexham County Borough Council and Cadwyn Clwyd.

Initiatives range from community arts projects through to heritage and biodiversity volunteer work which will assist in the maintenance and restoration of sites and features along local sections of the canal corridor.

Securing World Heritage Site Status is expected to bring a significant boost to the Wales visitor industry. The visually stunning 11 mile corridor from Chirk through to the Horseshoe Falls on the River Dee at Llangollen is rich in heritage and history, containing 168 notable features and structures
