Overview
Tiendeholmen renseanlegg is a municipal wastewater treatment plant serving Namsos, Norway, with a population equivalent of 25,904. It operates under Norway's implementation of the EU Urban Waste Water Treatment Directive.
Tiendeholmen renseanlegg is a municipal wastewater treatment plant located in Namsos, Trøndelag, Norway. It serves a population equivalent of 25,904, classifying it as a medium-sized agglomeration under Norwegian regulations. The plant is situated near the coast, within 50 km of the Norwegian Sea, and its operations are critical for protecting the local marine environment. As a Norwegian plant, Tiendeholmen renseanlegg is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), implemented through national regulations. For agglomerations of this size, secondary treatment is typically required, with more advanced treatment if the receiving waters are sensitive. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating a scale appropriate for its service population. The plant discharges treated wastewater into the Namsen River or nearby coastal waters, ultimately reaching the Norwegian Sea. This area supports diverse marine life, including fish stocks and seabird populations. Effective treatment at Tiendeholmen helps maintain water quality in the fjord system and reduces nutrient loading, which is vital for preserving the ecological balance of the Trøndelag coast.
Environmental context
Tiendeholmen renseanlegg discharges into the Namsen River, which flows into the Namsenfjorden and then the Norwegian Sea. This coastal region supports important fisheries and marine biodiversity. The plant's treatment performance is crucial for preventing eutrophication and protecting the sensitive fjord ecosystem, which serves as a nursery ground for fish and a habitat for seabirds.
