it's called the Maudlintown Gusher.
For the past two years, a mains water pipe in Antelope Road has been leaking 10,000 litres every hour. That's an unbelievable 87 million litres of water that has been going down the drain every year.
'I'm surprised Maudlintown is not in Pembroke by now,' said outgoing mayor Cllr. George Lawlor.
He said the seriousness of the leak had only come to light when the fire brigade complained about the low water pressure they encountered when tackling a recent house fire in Antelope Road.
'It only came to my attention then, although the council knew water was leaking but had difficultly in locating its source,' said Cllr. Lawlor.
However, some serious detective work involving council engineer James Whelan and Irish Water had isolated the leak and now contractors have been appointed to carry out the €25,000 repair after being given the green light by the county council.
'It wouldn't have been obvious because it was running along the back gardens, but we've got to the bottom of it now,' said Cllr. Lawlor.
Mary Roberts, from 6, Antelope Road, said the water appeared to be springing from her brother Ger's garden, which is next door, but workmen trying to fix the gusher - which runs like a stream along the bottom of some of the gardens - didn't know where it was coming from.
'They knocked down his shed because they thought it was coming from underneath it, now they say they don't know and it could be from the Faythe, the Green or the Rocks,' she said.
'The fire brigade ran out of water when they were down here, they should have come to our houses, we have plenty,' she said.
