A hydrophyte treatment system was constructed in Bielkowo in order to protect drinking water intake for the city of Gda.sk against surface and point sources of contaminants. The system consists of two subunits: a wet unit (pond), filled with water all the time and a dry unit (extension of the pond), designed for storm water. In the wet unit are placed dams constructed of medium size sand. The system, especially dams, is inhibited with macrophytes. The drainage system collects water percolating through dams, and directs it downstream. The system was constructed in 1997. After implementation of the system substantial improvement in water quality occurred.
