The designated toilet areas are outhouse-sized structures labelled TOILET.
There is a water pump for water. As for soda and juice and stuff.... well, you're sorta on your own. OK there will be some bottled water and sodas provided generously by the local bottling company for the festival, but that's only for the festival. Which... is what you're planning on being there for, so... I guess yeah, sodas and bottled water.
