Overview
ERQUY TU ES ROC wastewater treatment plant serves Erquy, France, in the Bretagne region. It is located near the coast and serves a population of approximately 11,969.
ERQUY TU ES ROC is a wastewater treatment plant located in Erquy, a commune in the Côtes-d'Armor department of Bretagne, France. The plant serves a population of about 11,969, placing it in the medium agglomeration category under French regulations. Its location near the coast means it plays a key role in protecting the marine environment. As a French plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the discharge enters sensitive areas. This likely refers to cubic meters per day or population equivalent. The plant discharges treated wastewater into the local watershed, which ultimately drains into the English Channel. The coastal environment supports diverse marine life and is important for local fisheries and tourism. Proper treatment helps prevent eutrophication and protects water quality in the sensitive coastal zone.
Environmental context
