Glastonbury Festival uses about 1.5 million gallons of water.
(This is far more than the normal local supply could provide and so a new water main was installed 10 years ago, supplying two-thirds of the festival’s needs, the other third is brought in by tanker from a reservoir seven miles away (hopefully a long way from the “lagoon”). The water is stored in five huge tanks before being pumped around the site to sinks, standpipes, cafes, stalls and any other areas that need it. More than 10 miles of pipes have been built beneath the fields over the years, with another 15 miles laid overground before the festival starts.)
