Overview
Langnes avlopsrenseanlegg is a wastewater treatment plant serving Tromsø, Norway, with a population equivalent of 15,500. It is located near the coast and operates under Norwegian regulations aligned with the EU Urban Waste Water Treatment Directive.
Langnes avlopsrenseanlegg is a municipal wastewater treatment plant located in Tromsø, Norway, serving a population equivalent of approximately 15,500. The plant is situated near the coast in the Troms region, an area characterized by its Arctic climate and proximity to the Norwegian Sea. As a Norwegian facility, the plant operates under national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this scale (15,500 PE), the directive requires secondary treatment as a minimum, with more stringent requirements if the discharge is into sensitive areas. The treated effluent is discharged into the local marine environment, ultimately reaching the Norwegian Sea. This coastal discharge is subject to Norwegian environmental regulations aimed at protecting the sensitive Arctic marine ecosystem, which supports diverse aquatic life including fish stocks and seabird populations.
Environmental context
The plant discharges into the coastal waters near Tromsø, which flow into the Norwegian Sea. This region is ecologically sensitive due to its Arctic marine environment, supporting important fisheries and migratory seabird populations. The discharge must meet Norwegian water quality standards to protect the local ecosystem.
