Overview
UWWTP ST ANNAPAROCHIE serves St.-Jacobiparochie in Fryslân, Netherlands, treating wastewater for approximately 9,800 people. The plant is located near the Wadden Sea coast and operates under EU Urban Waste Water Treatment Directive standards.
UWWTP ST ANNAPAROCHIE is a municipal wastewater treatment plant located in St.-Jacobiparochie, within the municipality of Waadhoeke in the province of Fryslân, Netherlands. The plant serves a population of approximately 9,800, placing it in the small-to-medium agglomeration category under EU classification. As a Dutch wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The Netherlands implements this directive through national legislation enforced by regional water authorities (waterschappen). The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), indicating a facility sized for its service population. The plant discharges treated effluent into local waterways that drain into the Wadden Sea, a shallow tidal sea and UNESCO World Heritage site known for its unique intertidal ecosystems and migratory bird habitats. The surrounding area is characterized by low-lying polder landscapes and intensive agriculture, making proper nutrient removal critical to prevent eutrophication in the sensitive coastal environment.
Environmental context
The plant's treated effluent flows into the Wadden Sea via local drainage canals and ditches typical of the Frisian polder system. The Wadden Sea is a highly productive intertidal zone that supports diverse marine life, including seals, fish, and millions of migratory birds. Nutrient loading from wastewater must be carefully managed to protect this ecologically sensitive area from eutrophication and algal blooms.
Frequently asked questions
UWWTP ST ANNAPAROCHIE is located at Middelweg-West in St.-Jacobiparochie, within the municipality of Waadhoeke in the province of Fryslân, Netherlands.
The plant serves approximately 9,800 people, classifying it as a small-to-medium agglomeration under EU standards.
The plant discharges treated effluent into local drainage canals and ditches that ultimately flow into the Wadden Sea, a sensitive coastal ecosystem.
As a Dutch plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. National implementation is overseen by regional water authorities.
Plants of this scale in the Netherlands typically employ secondary treatment with nutrient removal (nitrogen and phosphorus) to meet stringent EU standards, especially when discharging into sensitive areas like the Wadden Sea.
