Small Agglomerations, Big Challenges: Impact of the Urban Waste Water Treatment Directive (2024/3019) Recast for Wastewater Management in Poland

The foreseen implementation of the recast European Union Urban Wastewater Treatment Directive (EU) 2024/3019 will extend the previous regulation’s purpose to cover agglomerations from 1000 population equivalent upwards, and impose more stringent requirements on larger plants. Member States’ local authorities will be responsible for carrying out a range of organizational and infrastructural tasks, including the expansion of sewerage networks and the construction/modernization of wastewater treatment plants. This study presents an analysis aimed at assessing the readiness of small and medium-sized wastewater treatment plants in Poland to meet the new forthcoming requirements. The study examines the extent to which the present performance of small and medium-sized treatment plants in Poland complies with current regulations, and their readiness to comply with future environmental standards set by the new Directive. The structure of the national sewerage system is taken into account with the case study analysis of the present situation in the Opolskie Voivodeship. The novelty and methodological contribution of the study lies in bridging the regulatory analysis with local-scale operational data from selected facilities, as well as statistical data on the national wastewater treatment system published by Statistics Poland (GUS), linking local-scale WWTP performance with broader systemic conditions at the national level.
