Tests were done on the model station situated on the territory of Szczecin–Pomorzany Water Treatment Plant. The tested water came from Kurowski Channel. Kurów is the river bank water intake from Kurowski Channel – an artificial arm of Western Odra River. Pumping station is situated 300 m far from the Kurowski Channel. Water is supplied to the intake chamber of the pumps using the pipeline 1400. Three pumps of Flyght CP 3305 type in the alternating system force the raw water through two pipelines 700 PE to Pomorzany Water Treatment Plant situated 3 km far from it. Kurowski Channel is supplied from the main stream of Odra River and the inflowing underground waters of Wysoczyzna. Average composition of the water coming from Kurowski Channel is much more better than the water taken directly from Odra River.

Miedwie Lake is the biggest post-glacial lake of the West-Pomeranian Voievodship. At the same time it is the fifth of the largest lakes in Poland. As regards the geographical situation, Miedwie Lake is situated centrally between three big agglomerations i.e. Szczecin, Stargard Szczecinski and Pyrzyce (Fig. 1). The lake lies on the territory of three municipalities: Pyrzyce and Warnice in the District of Pyrzyce as well as Stargard Szczecinski in the District of Stargard (Rozmiarek 1983, Szyper 1990). At the moment, the reservoir is characterised with the regular, prolonged shape resembling an ellipse. Banks are shallow, regular and sometime very wet. The lake has the belt of the nearshore reaching locally tens metres far from the lake bank, what is the reason, together with the fact that the wind blows always here, that it is convenient for practising the various kinds of water sports. The lake area amounts to 3 527 ha; maximal depth – 43.8 m; average depth – 19.3 m; water capacity – 681.7 mln m3; shore-line length – 38.8 km; water level datum 14.1 m above sea level; maximal width 3.16 km; maximal length 16.2 km. The lake’s bottom is the lowest situated area on the territory of Poland.
