The P-Trees were a great success at the Roskilde Festival 2011 in Denmark, with more than 100,000 visitors and many of them using the P-TREE more than once. For Roskilde Aandeboom produced 50 P-Trees in the typical Roskilde Orange color. The P-Trees were placed on 2 different spots near the main stage. By using the P-Tree the festivals problem with public peeing was significant reduced. The P-Tree can be hooked up to a central sewage system or connected to a tank with a pump.
