The quantitative and qualitative state of water resources in Poland were presented in the paper. Discussed were selected factors shaping changes of water quality, including: improvement in sewage treatment balance, increase in the sewage system length, increase in the population number using sewage treatment plants, diminished outflow of organic substances and biogens in treated sewage. Presented state of water purity in Poland indicates, that despite improving quality, their state is still bad and the date when the desired state may be reached is still distant. The needs of municipal economy were presented against the state of water management, including the characteristics of selected systems of waterworks and sewage disposal systems development during the period of the last two decades, indicating the specific character of these systems in rural areas. ...
The paper presents an analysis of a chain index of water supply and wastewater infrastructure development dynamics in Poland in the years 2003-2013. The work aimed at determining the development index rate (relative growth) of water supply and sewage systems in Poland divided into 3 basic territorial units (rural, urban-rural and urban districts). Moreover, the paper describes the dynamics of changes concerning water consumption, share of population using water supplied by water supply systems, percentage of households possessing a bathroom and flush toilet and the share of population using sewage system during the analysed period. Conducted analyses used among others the chain index of dynamics to determine the rate of observed changes. The analysis revealed the greatest rate of changes for the indices characterising sewage system and the share of population using the system and wastewater treatment plants. Despite the fact that rural areas were characterized by definitely the highest values of the rate of changes and chain index of changes dynamics, the differences between rural and urban areas concerning water supply and wastewater infrastructure in Poland are still considerable. ...
