"Until this year, we always had to move dozens of barrels through the infield," a post on the official festival site said. "We had to bring in full barrels before, and during the shows and afterwards, we had to remove the empty ones. This caused a lot of avoidable traffic. The new pipeline helps us to protect the floor, and we also get rid of bottlenecks at the bar. You will not have to wait for the new barrel to be on tap anymore.
"The installation of the pipes and the enlarged drainage is a lasting investment in the infrastructure of Wacken. We pave the way for many more years of Heavy Metal at Wacken Open Air!"
More than 150 bands are expected to play the festival, including Megadeth, Marilyn Manson and Alice Cooper.
The Wacken Fest is Aug. 3 through 5.
