UWWTP Hooge Zwaluwe: Lage Zwaluwe Wastewater Treatment Plant, Netherlands

UWWTP Hooge Zwaluwe is a wastewater treatment plant located in Lage Zwaluwe, within the municipality of Drimmelen in the province of Noord-Brabant, Netherlands. The plant serves a population of approximately 4,950 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a Dutch plant, it operates under the national implementation of the EU UWWTD, which requires secondary treatment for agglomerations of this size discharging into freshwater or estuaries. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a modest scale consistent with its served population. The treated effluent is discharged into local surface waters that ultimately drain into the North Sea via the Rhine-Meuse-Scheldt delta. The region's low-lying geography and dense water network make effective wastewater treatment critical for protecting both local ecosystems and downstream coastal waters.

The plant discharges into the local water system within the Rhine-Meuse-Scheldt delta, a complex network of rivers and canals that flows into the North Sea. This delta supports diverse aquatic life and is an important migratory corridor for fish and birds. The surrounding area is characterized by polders and agricultural land, where nutrient management is essential to prevent eutrophication in downstream lakes and coastal zones.
