Vastavam web: We have seen the pipe lines to supply gas, kerosene, petrol and for drinking water but in Germany the organizers of a beer festival are laying seven kilometers of pipe line to supply beer for the participants. An underground beer pipeline is being laid for the Wacken Open Air (WOA) hard rock festival, which kicks off in northern Germany in August. It is part of a new 7km (four-mile) pipeline network, which organisers say will make the event more eco-friendly. The beer flow rate should reach six glasses every six seconds, thanks to the 35cm (14-inch) diameter pipeline. WOA is one of the world’s biggest heavy metal events. The line-up will include Megadeth, Alice Cooper and Trivium. The venue is on the edge of a village in Schleswig-Holstein with 1,850 residents. This year WOA will feature 150 bands, pumping out their rock numbers from 3-5 August.
German media report that WOA, spread over three days, attracts about 75,000 heavy metal fans each year. Each one consumes on average 5.1 litres (nine pints) of beer during the festival.
