Work on a vital flood-prevention scheme has been delayed again and construction on it may not start for another year.

The Government should more than double its flood-prevention funding to €1bn in a bid to prevent further havoc being caused to at-risk regions, the minister responsible for the area has said.

A flood prevention scheme, which could cost up to €3 million, should be completed in Glanmire by 2016, according to consultants designing project.
