Hammaro avloppsreningsverk - Skoghall, Sweden Wastewater Treatment Plant

Hammaro avloppsreningsverk is a municipal wastewater treatment plant located in Skoghall, Hammarö kommun, Värmlands län, Sweden. It serves a population of approximately 8,220 people, classifying it as a small to medium agglomeration under EU classification. The plant is situated near Edsviken, a bay of Lake Vänern, and its operations are integral to the local water management infrastructure. As a Swedish plant, Hammaro avloppsreningsverk operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Sweden's implementation of the directive includes additional national standards for nutrient removal, particularly in sensitive areas like the Baltic Sea catchment. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a scale appropriate for its service population. The plant discharges treated wastewater into the local watershed, which ultimately drains into Lake Vänern, Sweden's largest lake. Lake Vänern is a major freshwater resource and supports diverse aquatic life, including commercially important fish species. The plant's performance is critical to maintaining water quality in the lake and its downstream connection to the Göta älv river system, which flows to the Kattegat and the North Sea. Effective treatment helps protect this ecologically sensitive region from nutrient pollution and other contaminants.

Hammaro avloppsreningsverk discharges into the local watershed that feeds Edsviken, a bay of Lake Vänern. Lake Vänern is the largest lake in Sweden and a key freshwater ecosystem, supporting diverse aquatic life and serving as a drinking water source. The lake drains via the Göta älv river into the Kattegat, a strait connecting to the North Sea. The plant's operations are crucial for preventing eutrophication and maintaining water quality in this ecologically significant basin.
