Overview
TP 144 of Ivalo is a wastewater treatment plant serving Inari, Finland, with a population equivalent of 11,000. Located in the Lappi region, it operates under Finnish and EU regulations for wastewater treatment.
TP 144 of Ivalo is a wastewater treatment plant located in Inari, within the Lappi region of northern Finland. The plant serves a population equivalent of approximately 11,000, reflecting the scale of the local community in this sparsely populated area. As a Finnish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The designed capacity is 1.00 (likely in thousand cubic meters per day or similar units), indicating the plant's intended throughput. Finnish environmental authorities oversee compliance with national standards that transpose EU directives. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Gulf of Bothnia. The region's sensitive Arctic and subarctic ecosystems require careful management of nutrient loads to prevent eutrophication in downstream water bodies. The plant plays a key role in protecting the water quality of nearby rivers and the Baltic Sea.
Environmental context
The plant discharges into the local watershed within the Ivalojoki river basin, which flows into Lake Inari and then via the Paatsjoki River to the Barents Sea. This Arctic drainage system supports diverse aquatic life, including salmonid fish species, and is ecologically sensitive due to cold temperatures and short growing seasons. Nutrient removal is critical to avoid eutrophication in downstream lakes and coastal areas.
Frequently asked questions
TP 144 of Ivalo is located in Inari, within the Lappi region of northern Finland, near the Ivalojoki river.
The plant serves a population equivalent of approximately 11,000 people in the Inari area.
Treated wastewater from the plant is discharged into the local watershed, which flows into the Ivalojoki River and eventually reaches the Barents Sea.
As a Finnish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 10,000 population equivalent.
For agglomerations of this size, EU directives require secondary treatment, and in sensitive areas like the Baltic Sea catchment, additional nutrient removal may be required.
