Overview
UWWTP Geldermalsen serves approximately 25,561 people in Gelderland, Netherlands. The plant operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
UWWTP Geldermalsen is a municipal wastewater treatment plant located in Geldermalsen, Gelderland, Netherlands. It serves a population of approximately 25,561, classifying it as a medium agglomeration under EU regulations. The plant is situated in the rural-urban fringe of the Betuwe region, an area known for fruit cultivation and riverine landscapes. As a Dutch plant serving over 10,000 people, it falls under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum. The Netherlands implements this directive through national legislation, with additional nutrient removal standards for sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), indicating it is sized for its current load. The treated effluent is discharged into the local water system, which drains into the Linge River, a tributary of the Waal (Rhine delta). The Rhine-Meuse-Scheldt delta is a ecologically significant region supporting diverse aquatic life and migratory fish. The plant's operation helps protect downstream water quality in this densely populated and agriculturally intensive area.
Environmental context
The plant discharges into the Linge River, which flows into the Waal, a major branch of the Rhine delta. This delta system is ecologically sensitive, supporting diverse aquatic habitats and serving as a critical migratory corridor for fish species. The region's intensive agriculture and high population density make nutrient removal essential to prevent eutrophication in downstream lakes and coastal waters.
