WaterAid first became involved with Glastonbury Festival in 1994 thanks to the local Rotary group who suggested us to Michael Eavis. The rest, as they say, is history.
Our relationship with the festival has since gone from strength to strength and we are now one of their three main charities.
Each festival year, we receive a donation in return for the services and volunteers we provide at the festival.
Above all though, the festival gives us a fantastic platform to let people know about us and our vital work. We can campaign and reach tens of thousands of people, and potentially millions worldwide who watch on TV and take an interest in the world's most famous music festival.
Glastonbury Festival is the ideal place to campaign, as people are more receptive to the issues of water and sanitation when they're at a festival than they are in their day to day lives.
Whether it's getting something to drink, queuing for the toilet or making sure their hands are clean, people are a step closer to the issues and can really start to understand what life is like for the 2.5 billion people in the world who do not have access to a toilet.
Over the years our presence has become bigger and better, and many WaterAid supporters say they first heard of us through the festival. We even got a visit from our President, HRH The Prince of Wales, in 2010 to help celebrate the 40th birthday of the festival.
