The clean-up campaign has started in Chorley after more than a month’s worth of rain fell in 48 hours.
500 sandbags have been handed out in Croston as the village centre was deluged under two feet of water.
It was the second time in three months that Chorley Council’s flood plan has been activated as the River Yarrow broke its banks, causing waves of disruption.
Mechanical sweepers are now clearing channels along the main routes affected by flooding in the village, and debris and litter is being swept out to try and ensure drains remain unclogged.
Coun Terry Brown, who oversees flooding issues for Chorley Council, said: “It started raining on Sunday and didn’t stop until Wednesday.
“We activated our emergency flood plan on Monday when the Environment Agency issued a flood alert on the River Yarrow which meant there was a possibility of flooding in Croston.
“We opened our sandbag store in the village and teams of our streetscene staff handed out sandbags to residents all afternoon and well into the evening.
“Then river levels and surface water seemed to drop overnight so we hoped we’d had the worst of it, but the rain just never stopped and on Tuesday afternoon the Environment Agency upgraded to flood alert to a flood warning which meant that flooding was expected.
“More than 500 sandbags were given out which helped protect people’s homes from the flooding overnight, although the village centre was under two feet of water.
“As the flood water subsided the next day, we moved in with mechanical sweepers clearing channels along the main routes affected by flooding.”
The Environment Agency is continuing to warn residents across the North West to remain vigilant as river levels start to fall.
Rainfall across the region cleared overnight but it has been warned there may be further showers across the region today and into the weekend.
Steve Moore, Regional Director for the North West Environment Agency, said: “The exceptional rainfall we have seen over the past few days has led to flooding across many parts of the North West and our thoughts are with those who have been affected over the past few days.
“Fortunately the forecast for today is that it will be much drier, allowing river levels to drop.
“While we may see a few more showers over the next few days they will not have a significant impact on river levels although our teams will continue to monitor them closely.
“We will continue to do everything we can to support flooded communities with advice, information and support as people come to terms with the impacts of this week’s floods.
“I would also urge people to remember not to walk or drive through flood water, which can be very dangerous.”
