Maghull Labour Action Team leader Lynn Gatherer is working with Sefton Council to get to the bottom of a deep problem after being flooded by complaints from local residents.
Lynn was contacted by residents of Bridge Farm Drive complaining that the road becomes submerged when it rains.
The Maghull Labour Action Team leader immediately contacted Sefton Council to ask for the problem to be resolved.
They have now confirmed that they are investigating the problem.
Lynn said: "I contacted Sefton Council about this issue as soon as residents in Bridge Farm Drive raised it with me.
"They immediately recognised the urgency of the concerns and have assured me that they are conducting an investigation. The first check they will make is to ensure the gully is in in full working order.
"I was assured the gully was checked as part of the previous cyclic cleansing which took place on May 11 last year, but the offending gully will be visited again."
Lynn thanked residents for flagging the problem up.
Lynn said: "I'd like to thank the residents of Bridge Farm Drive who raised the issue with the Maghull Labour Action Team and I'd like to thank Sefton Council for taking such swift action to remedy the problem.
"Hopefully now, the residents of Bridge Farm Drive will be able to go out after a downpour without having to put their wellies on first."
