Lincolnshire County Council has promised to replace a faulty valve in a street drain a year after river water from the Nene gushed into Lime Street at Sutton Bridge.
The village escaped serious flooding in the tidal surge on December 5 last year as the river banks held firm.
But water cascaded out through the drain on West Bank and into Lime Street.
Environment Agency workers put sandbags on top of the drain to stem the flow and the parish council has been trying ever since to have the drain repaired.
The drain was designed to allow excess water from the street to go into the river – but “flaps” were found to be jammed on the night of the surge and river water flowed into the street.
Sutton Bridge Parish Council heard on Tuesday that the county council has gone to a specialist contractor who will install a new valve by the end of February.
Parish council chairman Coun John Grimwood said: “I think the problem with the existing valve is a lack of maintenance.”
