Ilana and Yoram Inspector say that they have been aware of the leak, which spurts water onto the pavement outside their house in Priory Gardens, ever since they moved to the area in 2016.
The issue is worse during heavy rainfall, and creates a slip hazard for passers-by when it freezes in winter.
Thames Water has been called out to the leak multiple times in recent years, with the couple claiming that engineers have determined that the water comes from a natural source and not their home.
They added that their pleas for help with fixing the problem have been met with “silence” from Haringey Council.
“I try to put sand or salt on the leak when it freezes, but obviously I don’t have 100% control of it,” Mrs Inspector said.
“The pattern is that people start complaining, then we get a threatening letter from Haringey Council.
“They expect us to totally resolve something that’s been going on for a decade.”
Mr Inspector added that the couple hoped that they could have a “common-sense collaboration” with the local authority.
“The solution is simple – you need to try to identify the origin of it and try to divert it to another place, or if you cannot, then create some good drainage,” he said.
“We are open to allowing the council to do anything they need to do to solve it, and we will be as helpful as we can.
“But we definitely don’t feel it’s right that the responsibility has been put on us.”
Ward councillor Scott Emery, part of the Liberal Democrat opposition group, claimed that the council’s response has been “slow, inconsistent, and poorly communicated”.
“There’s been a persistent leak for nearly a decade, worsening recently,” he explained.
“In winter, it freezes into a dangerous sheet of ice. Despite repeated requests, Haringey has avoided meeting, bouncing it between officers and eventually going silent.”
Thames Water has been approached for a response.
A Haringey Council spokesperson said: “We are aware of this matter and will continue to work with Thames Water to find a way forward.”
