The Life Environment project »The Sustainable Rehabilitation of Landfill Site« has been established on the municipal solid waste landfill site in Ormoz, 
Slovenia. The technology comprises leachate treatment and recycling on vegetated landfill cover to achieve landfill stabilisation and easier public acceptance 
of reclaimed site. The aim is the reduction of landfill impact on the environment with the closed hydrological and pollution cycle within the landfill site. 
Rehabilitation was composed of temporary excavation and transposition of old wastes, drainage of underground water, sealing of the landfill bottom, collection 
and drainage of leachate water, refilling with old and new wastes, compaction of wastes, surface sealing of wastes with surface water and landfill gasses drainage, 
establishment of final evapotranspirative cap barrier with planting of trees, and installation of irrigation system for the reuse of treated leachate for 
the growth of the trees. As the first step of all the rehabilitation work on the landfill site, a constructed wetland has been constructed for treatment of leachate 
to immediately stop the direct pollution of nearby stream and agricultural land.
