Overview
UWWTP Hazerswoude-Dorp serves approximately 4,600 people in Zuid-Holland, Netherlands. The plant operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
UWWTP Hazerswoude-Dorp is a municipal wastewater treatment plant located in Hazerswoude-Dorp, a village in the municipality of Alphen aan den Rijn, Zuid-Holland, Netherlands. The plant serves a population of approximately 4,600 people, classifying it as a small agglomeration under EU regulations. As a Dutch plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for discharges into freshwater and estuaries for agglomerations above 2,000 population equivalent. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating it is sized for its small service population. The plant's treated effluent is discharged into the local water system, which ultimately drains into the North Sea via the Rhine-Meuse-Scheldt delta. This region is ecologically sensitive, supporting diverse aquatic life and serving as an important migratory corridor for fish and birds. Proper treatment helps protect downstream water quality in the delta and coastal areas.
Environmental context
The plant discharges into the local water network that feeds into the Rhine-Meuse-Scheldt delta, a complex system of rivers and estuaries flowing into the North Sea. This delta is ecologically significant, supporting diverse aquatic habitats and serving as a critical stopover for migratory birds. The North Sea coastal zone is also important for fisheries and marine biodiversity, making effective wastewater treatment essential to prevent nutrient enrichment and pollution.
