Sinkhole blamed on storage tank

An explanation has been offered for a ground collapse, initially described as “sinkhole”, at an unfinished housing estate last weekend.

Kerry County Council, which investigated Cahereen Heights Estate, Castleisland, yesterday said the cause of the collapse, which left a 10 by 5m hole, was a structural failure in the roof of an underground, storm-water holding tank.

Other underground storm water tanks in the green area of the estate have been fenced off from public access by the council as a precautionary measure, as has the area of ground collapse.
