Krasocin Wastewater Treatment Plant - Świętokrzyskie, Poland

The Krasocin wastewater treatment plant is located in the village of Krasocin, within województwo świętokrzyskie (Świętokrzyskie Voivodeship) in south-central Poland. It serves a small population of 1,281 residents, reflecting the rural character of the gmina Krasocin area. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) between 2,000 and 15,000. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity of 6,233 m³/day suggests it can handle peak flows well above current discharge volumes. Treated effluent is discharged into local watercourses that ultimately drain into the Pilica River, a tributary of the Vistula River, which flows into the Baltic Sea. The plant plays a key role in protecting the region's surface waters from untreated sewage, supporting aquatic life and downstream water quality in the Vistula basin.

The plant discharges into local streams that feed the Pilica River, a major tributary of the Vistula River. The Vistula flows northward through Poland into the Baltic Sea via the Gdańsk Bay. The watershed supports diverse aquatic ecosystems, including fish spawning grounds and migratory bird habitats. Secondary treatment reduces organic pollution, helping to maintain oxygen levels and prevent eutrophication in downstream waters.
