Overview
TP 994 of Aetsan kk is an advanced wastewater treatment plant in Sastamala, Pirkanmaa, Finland, serving approximately 4,500 people. It discharges treated wastewater into local water bodies, supporting environmental protection in the region.
TP 994 of Aetsan kk is an advanced wastewater treatment facility located in Sastamala, within the Pirkanmaa region of Finland. The plant serves a population of around 4,500 residents, contributing to the municipal wastewater management infrastructure of the area. Its advanced treatment level ensures high-quality effluent, meeting stringent environmental standards. The plant operates under Finland's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and agglomerations of this scale. The advanced classification indicates the use of tertiary processes such as nutrient removal, which is common in Finnish plants to protect sensitive Baltic Sea watersheds. The treated wastewater is discharged into local watercourses, ultimately draining into the Kokemäenjoki river basin and the Baltic Sea. This discharge supports the ecological health of downstream environments, including lakes and rivers that are vital for biodiversity and recreational use. The plant's location inland, away from the coast, reduces direct marine impact but still plays a role in regional water quality.
Environmental context
The plant's discharge enters local streams that flow into the Kokemäenjoki river system, which drains into the Baltic Sea. This watershed supports diverse aquatic life and is important for migratory fish species. The advanced treatment helps minimize nutrient loading, which is critical for preventing eutrophication in the Baltic Sea, a sensitive marine environment.
Frequently asked questions
TP 994 of Aetsan kk is located in Sastamala, in the Pirkanmaa region of Finland. The address is 72 Kiviniementie, Kiviniemi, Sastamala.
The plant serves approximately 4,500 people in the Sastamala area.
The treated wastewater is discharged into local watercourses that flow into the Kokemäenjoki river system, eventually reaching the Baltic Sea.
As a Finnish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas and agglomerations over 10,000 population equivalent. For smaller plants like this, secondary treatment is standard, but advanced treatment is provided to protect the Baltic Sea.
In Finland, plants serving populations of this size typically provide at least secondary treatment, with many employing advanced treatment (tertiary) to reduce nutrients. This is especially common in the Baltic Sea catchment area to combat eutrophication.
