UWWTP Dokkum - Municipal Wastewater Treatment in Fryslân, Netherlands

UWWTP Dokkum is a municipal wastewater treatment plant serving the town of Dokkum in the province of Fryslân, Netherlands. With a population equivalent of approximately 20,976, it is classified as a medium-sized agglomeration under EU regulations. The plant is situated in the northern part of the country, near the Wadden Sea coast. As a Dutch facility, UWWTP Dokkum 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, with permits issued by regional water authorities. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), indicating it is sized to handle the local population load. The treated effluent from UWWTP Dokkum is discharged into the local surface waters, which ultimately drain into the Wadden Sea, a UNESCO World Heritage site (though not explicitly named in the output). The Wadden Sea is an ecologically sensitive intertidal zone that supports diverse bird populations and marine life. The plant's proximity to the coast (within 50 km) means its discharge must meet stringent nutrient removal standards to protect the sensitive coastal ecosystem.

UWWTP Dokkum discharges into the local water system that drains into the Wadden Sea, a shallow coastal sea along the northern Netherlands. The Wadden Sea is a critical habitat for migratory birds, seals, and fish, and is recognized for its ecological importance. The plant's location within 50 km of the coast means its effluent can influence the nutrient balance and water quality of this sensitive marine environment. Dutch water authorities enforce strict phosphorus and nitrogen removal standards to prevent eutrophication in coastal waters.
