In the paper the quality fluctuations of leachate from municipal landfill in Gdansk (Poland) over the last 5 years and evaluation of a wetland system designed for treatment of the leachate are discussed.The research has been conducted during the 5 years period. The constructed wetland for leachate treatment, consisting of 2 horizontal subsurface flow reed beds, working in parallel was built in 2001. In the period 2005-06 it underwent modernization due to unsatisfactory treatment results caused by clogging of the beds. The treatment effectiveness after modernization is satisfactory. The effluent from bed I met Polish outflow standards, while in the effluent from bed II COD, total N and TSS exceeded the required concentrations. In spite of this, pre-treatment of leachate (iron removal) should be quickly introduced to protect the system against the repetition of clogging problems
