"And what have we achieved?" asks leader and group founder Peter Weston. "A lot of self-satisfaction and a sense that we really have made that difference.
"We pick up about eight bags a week on average, equating to an estimated 400 bags a year. Stack those bags together and it would cover the swing park in the Recreation Ground to about 18 inches high... kind of puts a different perspective on things!"
Of all the litter they collect, they find the most puzzling is the dog fouling, put as requested in plastic bags - and then thrown into the hedgerow.
"But," Peter adds "we have come to the conclusion that as with all communities, we cannot get away from litter, some is unintentional, a lot is the result of a 'don't care' attitude, and some is intentional.
"It's the nature of human kind that we will deposit rubbish wherever we go, that is the reason why we as a group venture out and try to minimise its effect."
The group also hopes that, with Longridge entering the Best Kept Village competition this summer, more people will be encouraged to think before they throw, help to make a difference and give the town that edge over other competitors.
The group collects litter regularly from John Smith's Playing Field and park, the Recreation Ground and children's play area, Towneley Gardens, the War Memorial, Mardale playing fields and swing park, Preston Road from the Grimsargh village sign up to the Old Oak, Shay Lane and - when they can - the surrounding residential streets in Longridge.
"We go out and as often and when it suits us," Peter explains. "Being a volunteer means just that, we are not a regimented group, we try to communicate with each other so that we know what each is doing or has done, and we meet about every two months or so."
Full support is given by Ribble Valley borough and Longridge Town councils, both having a representative at the group's informal meetings.
"There is a view that what we do just encourages people to throw litter in the knowledge that we will come round and pick it up," said Peter.
"Yes, that could be the case but we would say that is only in the minds of the minority - hopefully the majority see the difference we make and will be encouraged to join us and keep it going."
