Floodwater in the heart of Ewell Village is unlikely to recede before the end of the month the council has warned.
The flooding, fed by springs, has already covered the pavement and part of the road outside Bourne Hall Park for almost two months.
An Epsom Council spokesman said the county council ensured all drains were clear last week and there was "no immediate solution".
He said: "As the weather improves, the water will reduce but probably not until the end of March. For the future, a meeting will be arranged to discuss measures to relieve any repeat of the current situation.
"One possible solution could be to dig up the existing drains, pipes and channels under the road and renew with larger pipes - this would mean extensive works with traffic management and disruption."
He said the existing drainage pipes, which are just 10cm in diameter, could only be replaced in the summer.
