Overview
TINTENIAC wastewater treatment plant in Tinténiac, Bretagne, France, serves 2,900 people with advanced treatment. It discharges 517.35 m³/day and has a designed capacity of 6,000 m³/day.
The TINTENIAC wastewater treatment plant is located in Tinténiac, a commune in the Ille-et-Vilaine department of Bretagne, France. It serves a population of approximately 2,900 residents, classifying it as a small agglomeration under French and EU regulations. The plant is situated on the Quai de la Donac, near the Donac River. The facility provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,000 m³/day and an average discharge volume of 517.35 m³/day, the plant operates well within its capacity, indicating efficient performance. The advanced treatment level likely includes nutrient removal to protect sensitive receiving waters. The treated effluent is discharged into the Donac River, which flows into the Ille-et-Rance Canal and eventually reaches the Rance River estuary and the English Channel. This water body supports diverse aquatic life and is part of the regional hydrological network. The plant's advanced treatment helps minimize nutrient loading and protects downstream ecosystems.
Environmental context
The TINTENIAC plant discharges into the Donac River, a tributary of the Ille-et-Rance Canal, which connects to the Rance River. The Rance flows into the English Channel near Saint-Malo, a coastal area with important marine habitats. The region's watershed supports migratory fish species and estuarine ecosystems. Advanced treatment reduces the risk of eutrophication in the downstream river and coastal waters.
