The article takes up an attempt to present the changes that has occurred in the water management at the beginning of the 21st century in the area of Silesian Voivoideship. Communes situated within the boundaries of Klodnica catchment, closed by the section of Gliwice, were analysed as an example of water management in the area which undergoes a strong anthropopression. Klodnica catchment is an area where all the elements of the geographical environment were transformed, but it was the water environment that was changed most visibly. At the beginning of the 21st century, there were a lot of changes conducted in Poland, not only political, but also in the economic and legal sectors. Owing to these factors, the following changes appeared: water consumption, the structure of distribution of water among different branches of economy and the water and sewage system infrastructure. The effect of these changes is the decrease in water consumption and sewage discharge as well as upgrading the technologies of its treatment (Absalon 2007).
