TP 162 of Forssan kt - Advanced Wastewater Treatment in Jokioinen, Finland

TP 162 of Forssan kt is an advanced wastewater treatment facility located in Jokioinen, within the Forssa region of Kanta-Häme, Finland. The plant serves a population of approximately 3,600 people, reflecting its role as a small-scale municipal treatment facility in a rural area. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive areas under Finnish and EU regulations. The plant operates under Finland's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for discharges into sensitive water bodies. The treated wastewater is discharged into local streams that eventually drain into the Kokemäenjoki river basin and ultimately the Gulf of Bothnia. This discharge supports the ecological health of downstream waters by reducing nutrient loading and protecting aquatic habitats.

The plant discharges into small watercourses in the Kanta-Häme region, which flow into the Kokemäenjoki river system and eventually the Gulf of Bothnia. This watershed supports diverse aquatic life and is important for migratory fish species. Advanced treatment helps minimize eutrophication risks in the sensitive Baltic Sea environment.
