Three families whose homes have suffered regular flooding for the past five years have said the Department for Infrastructure has ignored their pleas for help.
Last Saturday Storm Deirdre caused flood water to rush from underground pipes, demolishing a pillar, ripping up a metal fence and swelling up in the grounds of the three cottages along Sheskin Road near Greysteel.
Declan Crumley, who lives in one of the houses, said if it wasn't for the fast actions of his neighbour - who used a digger to create a gully that allowed the water to flow down the hill - the insides of all three homes would have suffered serious damage.
"For the past five years every time there is heavy rain these three houses are flooded but last Saturday was one of the worst I've ever seen," he told the Belfast Telegraph.
"The water came right up to the doorstep and if it wasn't for the man who lives next door getting a digger and making a gully, the insides of the houses would have been ruined.
"I think the underground pipes aren't big enough to cope with huge amounts of water. I have contacted the department numerous times and so have my neighbours, so they are well aware of the problem and the length of time it has been going on.
"One other time the water came at such a force it lifted the concrete I had laid at the entrance to my house - and it takes some amount of power to lift concrete.
"I reported that and the men came out threw a blob of tarmac down and told me they would be back.
"That was over a year ago and they've yet to reappear.
"Our big worry is if there is a storm like last Saturday's and none of us are around to divert the flood water it will get inside the houses and we will lose everything.
"It shouldn't be up to us to keep a digger handy in case there is heavy rain but we can't get that message through to the department responsible."
The Department for Infrastructure said: "This issue was brought to the attention of DfI Roads earlier this week."
It added: "We plan to carry out an investigation to determine if the road drainage systems are contributing to this flooding."
