 | | Flowing eastward and then northward from the Carpathian Mountains of southern Poland to its delta near Gdansk on the Baltic Sea, the Vistula River forms a giant letter S. With its branches, including the Bug, Wieprz, San, Narew, Nida, Pilica, Brda, and Wierzyca rivers, the Vistula drains a basin of about 194 000 km2. |
 | | The middle and lower sections of this river are considered to be one of Europe’s most exceptional areas of natural and landscape value, with meanders, ox-bows, steep banks and sand islands. |
 | | In the early 1990s, municipal systems in Poland discharged about 900 000 million m3 of untreated sewage, while about I 400 000 m3 were treated mechanically and/or biologically with an average treatment efficiency of 64, 64, 23 and I7% for BOD.5, COD, N, and P respectively. |
