Overview
Dokka renseanlegg is a municipal wastewater treatment plant serving Dokka, Norway, with a population equivalent of 8,190. It operates under Norway's implementation of the EU Urban Waste Water Treatment Directive.
Dokka renseanlegg is a wastewater treatment facility located in Dokka, Nordre Land municipality, Innlandet county, Norway. The plant serves a population of approximately 8,190, classifying it as a small to medium agglomeration under Norwegian and EU regulatory frameworks. As a Norwegian plant, Dokka renseanlegg is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), transposed into national law. For agglomerations of this size (between 2,000 and 10,000 population equivalent), the directive requires at least secondary treatment, with more stringent requirements if the discharge is into sensitive areas. It is expected to meet these regulatory standards. The treated effluent from Dokka renseanlegg is discharged into the local watershed, which ultimately drains into the Randsfjorden lake, one of Norway's largest lakes, and then via the Drammenselva river to the Oslofjord. This water body chain supports diverse aquatic life and is important for regional recreation and ecology.
Environmental context
Dokka renseanlegg discharges into the local watershed that feeds Randsfjorden, a large lake in Innlandet county. From Randsfjorden, water flows through the Drammenselva river into the Oslofjord, a fjord system connected to the Skagerrak and North Sea. The lake and river support diverse fish populations, including brown trout and Arctic char, and are used for recreation and drinking water. Protecting water quality in this system is critical for maintaining ecological health and downstream uses.
