Overview
UWWTP Oude Tonge serves approximately 9,500 people in Oude-Tonge, Zuid-Holland, Netherlands. The plant is located near the coast and discharges into local waterways.
UWWTP Oude Tonge is a municipal wastewater treatment plant serving the town of Oude-Tonge on the island of Goeree-Overflakkee in the province of Zuid-Holland, Netherlands. The plant has a designed capacity of 1.00 cubic meters per day and serves a population of approximately 9,500 people. As a Dutch wastewater treatment plant, it operates under the European Union's 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. The plant's treated effluent is discharged into local surface waters that eventually drain into the North Sea. The surrounding area is characterized by polders and coastal ecosystems, making proper treatment essential for protecting water quality in this low-lying delta region.
Environmental context
The plant discharges into local canals and waterways that flow into the Grevelingenmeer or Haringvliet, both part of the Rhine-Meuse-Scheldt delta system, ultimately reaching the North Sea. This coastal environment supports diverse aquatic life and is an important area for migratory birds. The region's low elevation and dense water management infrastructure require careful treatment to prevent nutrient pollution and maintain ecological balance.
