Mokrsko Wastewater Treatment Plant - Secondary Treatment for 716 Residents in Łódzkie

Mokrsko wastewater treatment plant is located in the village of Mokrsko, within the gmina Mokrsko, powiat wieluński, in the województwo łódzkie region of Poland. The plant serves a population of 716 and operates under secondary treatment, which is the standard biological treatment required for smaller agglomerations under Polish and EU regulations. The plant has a designed capacity of 2016.00 cubic meters per day and currently discharges 102.09 cubic meters of treated wastewater daily. As a facility serving fewer than 2,000 people, it falls under the EU Urban Waste Water Treatment Directive's less stringent requirements, though secondary treatment ensures effective removal of organic matter and suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Warta River basin, part of the Oder River system flowing into the Baltic Sea. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region's aquatic habitats.

The plant's discharge enters local streams within the Warta River catchment, which flows northward to the Oder River and ultimately into the Baltic Sea. This inland location, over 50 km from the coast, reduces direct marine impact. The surrounding area includes agricultural land and small water bodies that benefit from nutrient removal provided by secondary treatment, helping to prevent eutrophication in downstream waters.
