Nowy Jadow Wastewater Treatment Plant, Nowy Jadów, Mazowieckie, Poland

Nowy Jadow is a wastewater treatment plant located in the village of Nowy Jadów, within the gmina Jadów, powiat wołomiński, województwo mazowieckie, Poland. The plant serves a population of 1,710 and is part of the municipal infrastructure for this rural community in central Poland. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 15,000. The designed capacity is 3,450 m³/day, and the current discharge volume is 243.82 m³/day, indicating ample reserve capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Bug River, a major tributary of the Narew River, which flows into the Vistula River and then to the Baltic Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from nutrient pollution.

The plant discharges into small streams that feed the Bug River, which flows through eastern Poland into the Narew and Vistula rivers, eventually reaching the Baltic Sea. This watershed supports diverse aquatic life and is important for migratory fish. The secondary treatment reduces organic load and suspended solids, helping to maintain water quality in the sensitive lowland river ecosystems of the region.
