Malmbergskajens reningsverk - Wastewater Treatment Plant in Ytterlännäs, Sweden

Malmbergskajens reningsverk is a municipal wastewater treatment plant located in Ytterlännäs distrikt, within Kramfors kommun, Västernorrlands län, Sweden. The facility serves a population of approximately 8,559 people, placing it in the small-to-medium agglomeration category under Swedish and EU regulations. As a Swedish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Swedish environmental standards typically mandate nutrient removal for plants discharging into sensitive areas. The plant's treated effluent likely discharges into the Ångermanälven river system or a nearby coastal water body, given its proximity to the coast (within 50 km). The receiving waters ultimately flow into the Gulf of Bothnia, part of the Baltic Sea. This region supports diverse aquatic life and is important for local fisheries and recreation.

The plant is located near the Ångermanälven river basin, which drains into the Gulf of Bothnia, a northern arm of the Baltic Sea. This coastal area is ecologically sensitive, supporting diverse fish species and migratory birds. The Baltic Sea's brackish waters are vulnerable to nutrient pollution, making effective wastewater treatment critical for preventing eutrophication and maintaining water quality.
