Overview
UWWTP Heiloo serves 40,300 people in Heiloo, Noord-Holland, Netherlands. The plant operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
UWWTP Heiloo is a municipal wastewater treatment plant located in Heiloo, Noord-Holland, Netherlands. It serves a population of approximately 40,300, classifying it as a medium agglomeration under EU regulations. The plant is situated in a region characterized by dense population and extensive water management infrastructure. As an EU member state, the Netherlands implements the Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. For plants serving over 10,000 people in sensitive areas, tertiary treatment may be required. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a facility sized to handle the local wastewater load. The treated effluent from UWWTP Heiloo is discharged into local waterways that ultimately drain into the North Sea. The Netherlands' low-lying geography and extensive canal systems mean that water quality management is critical for both ecological health and flood control. The plant plays a key role in protecting the region's surface waters from nutrient pollution and pathogens.
Environmental context
UWWTP Heiloo discharges into the local water system, which flows through canals and rivers in the Rhine-Meuse-Scheldt delta before reaching the North Sea. This coastal region supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's nutrient removal performance is critical to preventing eutrophication in downstream waters, including the Wadden Sea, a UNESCO World Heritage site (though this designation is not certain for the immediate discharge area).
