Overview
Bistrup wastewater treatment plant serves Birkerød in Region Hovedstaden, Denmark. It has a designed capacity of 1.00 and serves a population of 4,712.
Bistrup wastewater treatment plant is located in Birkerød, within the Rudersdal Kommune of Region Hovedstaden, Denmark. The plant serves a population of approximately 4,712 and has a designed capacity of 1.00, indicating it is a small-scale facility. It operates under Danish environmental regulations, which implement the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant is situated within 50 km of the coast, and its treated effluent likely discharges into local watercourses that eventually reach the Øresund strait, a marine environment connecting the Baltic Sea to the North Sea. The plant plays a role in protecting the local watershed and downstream coastal ecosystems from nutrient pollution.
Environmental context
Given its location in Birkerød, treated wastewater likely flows into small streams or lakes within the Mølleåen catchment, which drains into the Øresund. The Øresund is a sensitive marine environment supporting diverse aquatic life, including fish and bird populations. The plant's proximity to the coast (within 50 km) means its nutrient discharges could contribute to eutrophication in coastal waters, making effective treatment important for ecological health.

As a Danish plant, treated effluent is typically discharged into local watercourses that drain into the Øresund strait.
Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 require appropriate treatment. Bistrup, serving 4,712 people, falls into this category and must meet secondary treatment standards.
In Denmark, plants of this scale typically provide secondary treatment, including biological processes, to reduce organic matter and nutrients before discharge, in compliance with national regulations implementing the EU directive.
