A section of the Grand Canal in Dublin has been drained due to the partial collapse of a sewer.

The fault occurred on Sunday near Suir Road in Inchicore.

It is understood that approximately 750 metres of the canal was emptied after water from the canal flowed into the sewer on Sunday evening.

Irish Water says that no sewerage was released into the canal or local environment following the partial collapse of a 'trunk sewer'.

It said that it had no impact on local homes and businesses and the sewer remains operational.

Yesterday, Waterways Ireland, the cross-border organisation responsible for the country's inland waterways, notified boat owners of a major breach between Grand Canal Lock 1 and Lock 2.

It is understood the section of the canal will remain closed for a number of weeks while repairs are carried out.

The Environmental Protection Agency has been made aware of the incident.

Irish Water says an investigation is underway into the cause of the collapse.

The utility's regional operations lead John O'Donoghue said there was no overflow at Ringsend as the canal section was drained.

Inland Fisheries Ireland said there were about 1,000 fish including eel and pike in the section, most of which have been collected and taken to another part of the canal.

Inland Waterways Ireland said a temporary dam is due to be in place tomorrow but the canal will not be completely re-watered until all repairs are finished.
