Alvdal renseanlegg - Wastewater Treatment Plant in Alvdal, Norway

Alvdal renseanlegg is a municipal wastewater treatment plant located in Alvdal, Innlandet, Norway. Serving a population of around 6,400, it is classified as a small to medium agglomeration under Norwegian regulations, which follow the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is situated in the Glomma river basin, a major watercourse in eastern Norway. As a facility serving fewer than 10,000 people, Alvdal renseanlegg is subject to national requirements that typically mandate secondary treatment or equivalent, in line with the EU directive's standards for inland freshwater discharges. Norwegian plants of this scale commonly employ biological treatment methods to meet effluent quality standards. The treated wastewater is discharged into the local water system, which ultimately drains into the Glomma River. The Glomma flows southward through Innlandet and Viken counties before emptying into the Oslofjord. The river supports diverse aquatic life and is an important ecological corridor in the region. The plant's operations contribute to protecting water quality in the Glomma catchment area.

Alvdal renseanlegg discharges into the Glomma River basin, which drains into the Oslofjord, a fjord connected to the Skagerrak and the North Sea. The Glomma is Norway's longest river, supporting diverse fish species such as Atlantic salmon and brown trout. The plant's location in the upper reaches of the basin means its effluent quality is critical for maintaining ecological health downstream, particularly in sensitive freshwater habitats.
