The study concerns waste and waste water management in municipalities located within borders of national parks in Poland. In the case, the desired direction of development is understood as undertaking pro-environmental measures, such as: the development of a collective sewage network and household sewage treatment facilities in place of holding tanks, and organized waste management, effective segregation of generated waste for future reutilization. The analysis is based on statistical data for the years 2019-2022obtained from the Local Data Bank (BDL). The multi-criteria analysis involved following stages: calculation of selected diagnostic variables for each municipality, normalization of indicators for the selected features to achieve their comparability, designation of a synthetic indicators describing the rate of wastewater and waste management. The obtained synthetic indictors enable to determinegroups and types of municipalities related to the level of waste and wastewater management and to set up their spatial distribution within national parks. Six administrative units (11,7%) exhibit high-level waste management and above-average wastewater management. The largest group of the municipalities (57%) consists of units rated as average. No correlation can be observed between the level of waste and sewage management in individual municipalities and their location within the boundaries of a particular national park.
