German heavy metal music festival organizers for the upcoming Wacken event have come up with a novel idea on how to preserve the environment and quench the thirst of attendees. They have created an underground beer pipeline buried 2.6 feet that will pump 105,000 gallons of naturally chilled beer from 4.3 miles away to the taps at the festival. It is estimated that 75,000 people and 150 bands will be attending the festival, and each person will consume 5.4 quarts of beer over the three day event. This has meant that many delivery trucks were required in the past to sate the thirst of the ruckus crowd; and the tires on these trucks destroyed the ground with their heavy loads of beer. To repair the damage takes a great deal of time as the festival is held on farmland. Because the pipeline is laid deeply into the ground, normal farming practices can immediately resume after the festival is over. The new pipeline will carry about 400,000 liters (105,000 gallons) of beer through the grounds of Wacken Open Air Festival in northern Germany. The 75,000 metal fans who attend the event each year consume an average of about 5.1 liters of beer over the three-day festival, according to the statistics portal Statista. This compares to 3.1 liters per person for the Rock am Ring Festival. The pipeline is being built to stop the ground being torn up by beer trucks.
