MINIHY TREGUIER_LE BILO is an advanced wastewater treatment plant located in Tréguier, in the Brittany region of northwestern France. The facility serves a population of approximately 4,000, classifying it as a small agglomeration under EU classification. Its location near the coast places it in a sensitive environmental area. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,000 m³/day and a current discharge volume of 713 m³/day, the plant operates well within its capacity. Advanced treatment typically includes nutrient removal, which is important for protecting coastal waters from eutrophication. The treated effluent is discharged into the local watershed, which drains into the English Channel via the Jaudy River estuary. This coastal region supports diverse marine life and is important for local fisheries and tourism. The plant's advanced treatment helps minimize nutrient and pollutant loads to the sensitive coastal environment.
