Community groups in Huddersfield and Calderdale are to benefit from the Leeds Festival.
They and other groups will be given camping equipment salvaged from the sprawling festival site.
Tens of thousands of music fans descended on Bramham Park for the huge festival, which ran over the Bank Holiday weekend.
The festival was hit by heavy rain, which turned parts of the site into a quagmire, but mostly the festival goers enjoyed fine weather.
But they left behind hundreds of tents, sleeping bags and mats which have now been salvaged by a group called Everything is Possible.
They are now cleaning up more than 500 tents, 470 sleeping bags and 390 roll mats for 40 local community organisations around Yorkshire and Lancashire.
An army of volunteers working for the charity moved on to the festival site as the music fans departed.
Charity spokesman Bob McDougall said: “Every year thousands of pieces of camping equipment are left behind by festival goers and are collected by the organisation at Leeds Festival.
“This is becoming an event well known by local community organisations around Yorkshire, and they are now using the expression Happy Salvage Day.
“It is like Christmas for local communities. Instead of toys they’re getting camping equipment that they will be able to use for their activities”.
Groups set to benefit from this year’s salvage day include organisations in Huddersfield, Halifax, Skipton, Bradford, Keighley, Harrogate, Leeds, Ilkley, Manchester and York.
The project is supported by the British Council, the European Commission, Beacons Festival and Festival Republic.
Meanwhile, Leeds Council is to ask the organiser of the Leeds Festival to foot the bill for the clean-up of the city centre.
Council workers were brought in on Monday to clean mud-caked streets caused as music fans made their way home from the three-day event.
Clr Mark Dobson said he hoped bosses would “contribute to the excess cost”.
Melvin Benn, the festival organiser, said: “We will of course discuss this issue and any other concerns.”
