Slite avloppsreningsverk - Advanced Wastewater Treatment in Gotlands län, Sweden

Slite avloppsreningsverk is an advanced wastewater treatment plant located in Boge Mojner, Gotlands kommun, Gotlands län, Sweden. The plant serves a population of 2,146 and has a designed capacity of 8,000 m³/day, with a current discharge volume of 336.88 m³/day. As an advanced treatment facility, Slite avloppsreningsverk provides a higher level of treatment than the secondary standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations over 2,000, and Sweden applies stringent nutrient removal standards in sensitive areas like the Baltic Sea. The plant's proximity to the coast (within 10 km) means its treated effluent likely discharges into the Baltic Sea, a brackish water body sensitive to eutrophication. The plant's advanced treatment helps reduce nutrient loads, protecting the marine environment and supporting regional water quality goals.

The plant discharges into the Baltic Sea, a semi-enclosed brackish sea with limited water exchange, making it highly sensitive to nutrient pollution. The Baltic Sea faces eutrophication challenges from nitrogen and phosphorus inputs. Slite avloppsreningsverk's advanced treatment reduces these nutrients, helping to protect coastal ecosystems and support the health of the sea's diverse aquatic life, including fish and migratory birds.
