Overview
GRAESTED wastewater treatment plant serves Græsted in Region Hovedstaden, Denmark, with a population equivalent of 5,466. It operates under EU Urban Waste Water Treatment Directive standards for small agglomerations.
GRAESTED wastewater treatment plant is located in Græsted, a town in Gribskov Kommune, Region Hovedstaden, Denmark. The plant serves a population of approximately 5,466 people, classifying it as a small agglomeration under EU regulations. As a Danish facility, GRAESTED operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations above 2,000 population equivalent discharging into freshwater or estuaries. For smaller plants like this, appropriate treatment must prevent environmental harm. Denmark enforces stringent national standards aligned with the directive, often including nutrient removal to protect sensitive coastal waters. The plant's treated effluent likely discharges into local streams or groundwater that drain into the Kattegat or Øresund strait, part of the Baltic Sea. This region supports diverse marine life and is ecologically sensitive to nutrient pollution. The plant plays a key role in maintaining water quality in the surrounding watershed and downstream coastal environment.
Environmental context
GRAESTED plant is situated in the northern part of Zealand, within the catchment area that drains into the Kattegat sea via small coastal streams. The Kattegat is a transitional water body between the North Sea and the Baltic Sea, supporting important fisheries and migratory bird populations. Nutrient loading from wastewater can contribute to eutrophication in these coastal waters, making effective treatment critical for local ecosystem health.
