Calderdale Council work teams were mobilised and worked through Monday night following the flash floods.
The sheer volume and intensity of water coming down from the hills - in just 24 hours the total rainfall was over half of the monthly average - led to drains being overwhelmed, causing localised flooding.
The Council, the community and other organisations are all involved in the clean-up.
In the immediate aftermath sweepers were out clearing the roads and footpaths from 6 pm to 3 am.
Highways staff were working to reduce the impact on roads, and structural engineers visited affected properties to make sure they were safe.
The council said flood damage led to the closure the A6033 Rochdale Road in Walsden / Todmorden – and particularly significant damage to the road at Kershaw Road just above Walsden train station.
Council staff are out on site working on the recovery with Network Rail and utilities companies.
The main damage to properties is sewage, flood water and silt in cellars and the ground floors of some homes.
Bulky waste collections are taking place to remove flood-damaged items, council staff and volunteers are visiting households in the area to find out the full impacts of the flooding.
The council is also handing out cleaning materials to affected residents.
Clean up kits are also available from the Customer First centre in Todmorden and by calling the Council on 0845 245 6000 – anyone who needs help or advice should also use this number.
Council leader Coun Tim Swift, said: “I’m really impressed with how quickly and tirelessly council staff, local people and other organisations are working on the clean up. I’d like to thank everyone for all the effort they have made to deal with the effects of such an intense burst of rain.
“A multi-million pound investment has been made in main river defences through Todmorden, but it’s very difficult to prevent flash flooding along hillside streams and culverts as occurred.
“Nevertheless the council and our partners, including the Environment Agency, remain committed to working with local communities to make homes and businesses as safe as possible from flooding.”
