Overview
UWWTP Westpoort Huishoudens in Amsterdam, Netherlands, is a closed advanced treatment plant with a designed capacity of 351,000 m³/day. It served the Westpoort area before decommissioning.
UWWTP Westpoort Huishoudens was a wastewater treatment plant located in the Westpoort district of Amsterdam, Netherlands, within the province of Noord-Holland. The plant was designed with an advanced treatment level and a capacity of 351,000 m³/day, indicating it served a large agglomeration. It is now closed, and its operational history reflects the Netherlands' commitment to high-standard wastewater management under the EU Urban Waste Water Treatment Directive (91/271/EEC). As an advanced treatment facility, it likely employed nutrient removal processes to meet stringent effluent standards for sensitive areas. The Netherlands, as an EU member state, requires tertiary treatment for large agglomerations discharging into sensitive waters. The plant's closure may be part of regional optimization, with flows redirected to other facilities like the nearby Amsterdam West or Amsterdam East plants. The plant's discharge would have entered the North Sea Canal, which connects Amsterdam to the North Sea. This waterway is ecologically significant, supporting migratory fish and estuarine habitats. The advanced treatment helped protect the Wadden Sea and North Sea ecosystems from nutrient pollution.
Environmental context
The plant discharged into the North Sea Canal, a man-made waterway linking Amsterdam to the IJmuiden locks and the North Sea. This canal is part of the Rhine-Meuse-Scheldt delta system, a critical European ecological corridor. The receiving waters support diverse aquatic life, including migratory fish species, and are subject to nutrient-sensitive conditions. The advanced treatment level helped minimize eutrophication risks in the coastal North Sea.
Frequently asked questions
The plant was located in the Westpoort district of Amsterdam, Noord-Holland, Netherlands, near the North Sea Canal.
The plant had a designed capacity of 351,000 m³ per day, indicating it served a large urban population.
The plant is listed as closed, likely due to regional optimization of wastewater infrastructure in Amsterdam, with flows redirected to other treatment facilities.
Under the EU UWWTD, large agglomerations (over 150,000 population equivalent) require advanced treatment when discharging into sensitive areas. This plant's advanced treatment level aligns with those requirements.
The plant discharged into the North Sea Canal, which flows to the North Sea, a sensitive marine environment protected under EU directives.
