It serves a population of 2,203 and is part of the municipal infrastructure for the Warsaw West County area. The plant provides advanced treatment, ensuring high-quality effluent before discharge. As a facility in Poland, Mokre Laki operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment levels based on agglomeration size and receiving water sensitivity. For a population of 2,203, secondary treatment is typically mandated, but the plant exceeds this with advanced treatment, indicating a commitment to environmental protection. The plant's effluent is discharged into local watercourses that ultimately drain into the Vistula River basin, which flows into the Baltic Sea. The advanced treatment helps protect downstream ecosystems, including the Vistula's diverse aquatic life and the sensitive Baltic Sea environment.

Mokre Laki discharges treated wastewater into local streams that feed into the Vistula River, Poland's longest river, which flows north into the Baltic Sea. The Vistula basin supports diverse aquatic habitats and is an important migratory corridor for fish. The advanced treatment at Mokre Laki reduces nutrient loads, helping to mitigate eutrophication in the Baltic Sea, a sensitive marine environment.
