Overview
LILLEROD wastewater treatment plant serves Lillerød, Denmark, in Region Hovedstaden. It operates under the EU Urban Waste Water Treatment Directive, serving a population of approximately 12,000.
LILLEROD wastewater treatment plant is located in Lillerød, Allerød Municipality, Region Hovedstaden, Denmark. The facility serves a population of around 12,035, placing it in the small-to-medium agglomeration category under EU classification. As a Danish plant, LILLEROD operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating it is appropriately scaled for its service area. The treated effluent from LILLEROD is discharged into local watercourses that drain into the Øresund, the strait between Denmark and Sweden. This coastal discharge contributes to the nutrient balance of the Baltic Sea, making effective treatment essential for protecting marine ecosystems and supporting regional water quality goals.
Environmental context
LILLEROD's treated wastewater flows into local streams and rivers that ultimately reach the Øresund, a key waterway connecting the North Sea to the Baltic Sea. The Øresund supports diverse aquatic life and is an important migratory corridor for fish and birds. Effective nutrient removal at the plant helps mitigate eutrophication risks in the sensitive Baltic Sea ecosystem.
