Overview
RIANTEC wastewater treatment plant serves Locmiquélic, France, with a designed capacity of 1.00 volume unit. It is located in the Bretagne region near the coast, supporting local sanitation infrastructure.
RIANTEC is a wastewater treatment plant located in Locmiquélic, a commune in the Morbihan department of Bretagne, France. The plant serves a population of 14,355, placing it within the medium agglomeration category under French and EU regulations. Its location near the coast in the Lorient area underscores its role in managing municipal wastewater for this coastal community. The plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. French regulations, transposing the directive, mandate appropriate treatment levels to protect sensitive coastal waters. The designed capacity of 1.00 volume unit suggests the plant is sized to handle the local population load. The plant's discharge likely enters the coastal waters of the Bay of Biscay via local waterways, contributing to the protection of marine ecosystems. The surrounding area includes the Blavet River and the Rade de Lorient, a semi-enclosed bay that supports diverse aquatic life and is important for regional biodiversity. Proper treatment helps maintain water quality in this ecologically sensitive coastal zone.
