UWWTP Rijsenhout - Wastewater Treatment Plant in Rijsenhout, Noord-Holland

UWWTP Rijsenhout is a municipal wastewater treatment plant located in Rijsenhout, a village in the Haarlemmermeer municipality of Noord-Holland, Netherlands. The plant serves a population of approximately 8,900 people, placing it in the small-to-medium agglomeration category under EU classification. As a Dutch plant, UWWTP Rijsenhout operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), and it is part of the national wastewater infrastructure managed by regional water authorities. The treated effluent from the plant is discharged into local waterways that ultimately drain into the North Sea via the Rhine-Meuse-Scheldt delta. The region is characterized by polders and canals, and the plant plays a key role in protecting the water quality of these sensitive lowland ecosystems, which support diverse aquatic life and are important for agriculture and recreation.

The plant discharges into the local canal and polder system, which is part of the larger Rhine-Meuse-Scheldt delta. This delta is a ecologically significant area that supports diverse aquatic habitats and migratory bird populations. The treated effluent ultimately reaches the North Sea, making nutrient removal important to prevent eutrophication in coastal waters.
