The paper presents the development of water supply networks and sewage systems in rural areas of Małopolskie and Podkarpackie Voivodeships in the Polish context. The scope of the thesis includes the analyses of length of water supply networks and sewage systems, number of people using them, number of water and sewage connections and volume of used water and volume of discharged sewage. The results of the study were presented in the graphs. The research material was taken from the reports on municipal infrastructure published by The Polish Central Statistical Office (GUS) for 2002–2012 and Local Data Bank (BDL) for 1995–2001. Though there has been a significant improvement in water supply and sewage systems, Poland will have great difficulty in meeting the requirements concerning their development in rural areas by 2015.
