UWWTP Oosterend - Closed Advanced Wastewater Treatment Plant on Texel, Netherlands

UWWTP Oosterend is a former wastewater treatment plant located in Oosterend, on the island of Texel in the province of Noord-Holland, Netherlands. The plant was designed with an advanced treatment level and a capacity of 2025 cubic meters per day, serving the local population on the island. Although the plant is now closed, it operated under the Netherlands' implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for discharges into sensitive areas. The island of Texel is a coastal region with sensitive ecological zones, necessitating high treatment standards. The plant's treated effluent would have discharged into the Wadden Sea, a shallow sea known for its rich biodiversity and important migratory bird habitats. The Wadden Sea is a UNESCO World Heritage site, though this designation is not explicitly mentioned in the input. The plant's closure may reflect consolidation of wastewater services on the island.

The plant is located on the island of Texel, within 10 km of the coast, and its treated effluent would have discharged into the Wadden Sea. The Wadden Sea is a shallow, nutrient-rich sea that supports diverse marine life, including seals, fish, and migratory birds. The area is ecologically sensitive, and advanced treatment helps protect water quality in this important coastal ecosystem.
