MOS Wastewater Treatment Plant, Szydłowiec, Poland - EU Regulatory Context

MOS is a wastewater treatment plant located in Szydłowiec, a town in the Mazowieckie Voivodeship of Poland. The facility serves a population equivalent of 7,296, classifying it as a small agglomeration under EU regulations. Its location in central Poland places it within the Vistula River basin, a major waterway that drains into the Baltic Sea. As a Polish plant serving fewer than 10,000 people, MOS is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge. Regulatory oversight ensures compliance with national and EU standards. The treated effluent from MOS likely discharges into a local watercourse that feeds into the Vistula River, ultimately reaching the Baltic Sea. The Vistula basin supports diverse aquatic ecosystems and is an important migratory corridor for fish species. Proper wastewater treatment at plants like MOS helps protect water quality in the region and downstream environments.

MOS discharges into a tributary of the Vistula River, Poland's longest river, which flows northward into the Baltic Sea. The Vistula basin supports diverse aquatic life, including fish species such as salmon and sturgeon, and provides critical habitat for migratory birds. Effective wastewater treatment at this plant helps maintain water quality in the river system and reduces nutrient loading to the Baltic Sea, which is sensitive to eutrophication.
