WaterAid has been working with Glastonbury since 1994 to do the very important job of keeping the festival’s toilets clean. That was the first year I attended the festival; I’ve been back many times, and this is my second year running working as a WaterAid volunteer on the loo crew. The charity’s work at the festival also raises awareness of the lack of access for many to basic sanitation: more than one in five people across the world don’t have access to decent toilets. Being here changes the way you think about these things we take for granted. I am glad to pull on a pair of rubber gloves and give something back to the festival.
