Cement dumped in drain caused Dunmurry housing estate flooding, probe finds
A housing estate flooded because cement was dumped in a nearby drain, an investigation has found.
Beech Grove in Dunmurry was inundated during heavy rain last month.
The Department for Infrastructure (DfI) said it had been unable to trace who had disposed of material which blocked a main drain in the area.
Lisburn and Castlereagh councillor Jonathan Craig said many residents were pensioners.
He added: "The drains were blocked with concrete, buckets, you name it. All the rubbish had been thrown down the drains.
"There was literally about 20 houses almost flooded out because of this."
Councillor Craig said the estate had been prone to flooding but work recently carried out by the DfI had changed that.
He added: "What angered me about it was, whenever road service actually does a good piece of work and resolves what was a very big problem in the area, you have these (people) come along and break every law in the book."
The DfI said in a statement that it had responded to a "flooding incident" at the estate on November 12.
The next day, an investigation found a blockage caused by building materials and plastic bottles.
A DfI spokesperson said: "Unfortunately, it has not been possible to determine how the materials made their way into the drainage system."
