Mechaniczno biologiczna Oczyszczalnia Sciekow w Mlawie - Mława Wastewater Treatment Plant

Mechaniczno biologiczna Oczyszczalnia Sciekow w Mlawie is a wastewater treatment plant located in Mława, in the Mazowieckie Voivodeship of Poland. It serves a population of about 28,000, making it a medium-sized agglomeration under EU classification. The plant is situated in an inland area, away from the coast, and discharges into local water bodies. As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's name indicates a mechanical-biological treatment process, which aligns with the directive's standards. The plant is designed to handle the wastewater from the served population. The treated effluent is discharged into a local river that eventually flows into the Vistula River basin, which drains into the Baltic Sea. The plant plays a crucial role in protecting the local watershed and downstream ecosystems from pollution, supporting water quality and aquatic life in the region.

The plant discharges into a tributary of the Wkra River, which flows into the Narew River, a major tributary of the Vistula. The Vistula ultimately drains into the Baltic Sea. The local watershed supports diverse aquatic habitats and is important for migratory fish species. The plant's treatment helps reduce nutrient loads, preventing eutrophication in downstream waters.
