Overview
TP 112 of Honkajoen kk is an advanced wastewater treatment plant in Honkajoki, Satakunta, Finland, serving approximately 4,300 people. It discharges treated wastewater into local water bodies.
TP 112 of Honkajoen kk is a municipal wastewater treatment facility located in Honkajoki, within the Satakunta region of western Finland. The plant serves a population of around 4,300, placing it in the small-to-medium agglomeration category under Finnish and EU regulations. The plant employs advanced treatment processes, which typically include biological nutrient removal and disinfection, ensuring high-quality effluent. As a Finnish facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 2,000 population equivalent and tertiary treatment in sensitive areas. The advanced treatment level suggests the plant meets stringent standards for phosphorus and nitrogen removal, common in Finland due to the Baltic Sea sensitivity. The treated effluent is discharged into local waterways that ultimately drain into the Baltic Sea via the Gulf of Bothnia. The plant plays a key role in protecting downstream aquatic ecosystems, including rivers and coastal zones, from nutrient pollution. Its advanced treatment helps reduce eutrophication risks in the Baltic Sea, a major environmental concern for the region.
Environmental context
The plant discharges into local rivers that flow through the Satakunta region and eventually reach the Gulf of Bothnia, part of the Baltic Sea. The Baltic Sea is highly sensitive to nutrient loading, and advanced treatment at this plant helps mitigate eutrophication. The surrounding watershed supports diverse aquatic life and is important for regional biodiversity.
