There were 3,220 toilets at Glastonbury.

(Hang on! That’s only one for every 55 people. They are emptied and cleaned throughout using vacuum tankers pulled by tractors. The effluent gets pumped into a huge lagoon (doesn’t that sound romantic) at the north of the site, where a machine picks out clothes, phones and other items that have been dropped. Before this separator was installed a few years ago, workers had to do the job in a boat. The waste is then transferred to 5,500-gallon tankers, which make 40 trips a day, day and night, to local sewage works. Most ends up 30 miles away at Avonmouth, on the Bristol Channel. Too much information?)
