In southern Sweden, several irrigation based on site treatment has been established the lastyears. Briefly they consist of a pound to storing leachate water with pre-treatment and asystem what irrigate vegetation. It could be areas of willow plantations designated for energy purposes or grass or as in same cases spontaneous vegetation.The use of willow have been studied since 1992. These tests have clearly shown that recycling of municipal wastewater in Salix plantations, can replace a large part of the conventional wastewater treatment, due to natural purification processes in the soil/plant system.During the last few years, several full-scale treatment plants based on the soil/plant systemhave been set up to treat leachate water from municipal solid waste (MSW) landfills.One other way to reduce leachate water is to use transpiration. On dry days leachate ispumping and irrigated ideal on top of landfills inside the leachate collection system.Rosenqvist Mek.Verkstad has developed the irrigation system "RWIS" for distribution ofwaste and leachate water into the plantation. The irrigation system has to be able to withstand trying conditions, without major maintenance in between harvests.
