TP 751 of Salon kt, Salo | Finland Wastewater

Overview

TP 751 of Salon kt serves approximately 49,000 people in Salo, Finland. The plant is located within 50 km of the coast and operates under EU wastewater treatment regulations.

TP 751 of Salon kt is a municipal wastewater treatment plant serving the Salo region in Varsinais-Suomi, Finland. The facility is situated in the Meriniitty district of Salon suuralue and provides wastewater treatment for an estimated population of 49,000. As a plant in Finland, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment based on population size. Under the EU directive, agglomerations with a population equivalent above 15,000 typically require secondary treatment, and those in sensitive areas may need tertiary treatment. Given its scale, TP 751 is expected to meet at least secondary treatment standards. The plant's treated effluent is discharged into local water bodies that eventually drain into the Baltic Sea. The Baltic Sea is a sensitive marine environment with limited water exchange, making nutrient removal crucial. The plant's proximity to the coast (within 50 km) underscores its role in protecting coastal water quality and supporting the ecological health of the Archipelago Sea and the broader Baltic ecosystem.

Environmental context

TP 751 of Salon kt discharges treated wastewater into local waterways that flow into the Archipelago Sea, a part of the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with high ecological sensitivity, facing challenges from eutrophication due to nutrient inputs. The plant's operations are critical for controlling phosphorus and nitrogen loads to this vulnerable marine environment, which supports diverse aquatic life and is an important migratory corridor for fish and birds.

Frequently asked questions

TP 751 of Salon kt is located at Katkiluodonkatu 10 in the Meriniitty district of Salon suuralue, Salo, in the Varsinais-Suomi region of Finland.

The plant serves approximately 49,000 people in the Salo area, making it a medium-to-large agglomeration under EU classification.

Treated wastewater from the plant is discharged into local water bodies that flow into the Archipelago Sea and ultimately the Baltic Sea. The plant's coastal proximity requires careful nutrient management to protect marine water quality.

As a Finnish wastewater treatment plant, TP 751 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 15,000 population equivalent and may require tertiary treatment in sensitive areas like the Baltic Sea basin.

For plants of this scale in Finland, secondary treatment is standard, often with nutrient removal (nitrogen and phosphorus) to meet Baltic Sea protection requirements. Many plants also employ biological or chemical processes to reduce eutrophication impacts.
