Overview
Milizac Treleon is a secondary wastewater treatment plant serving 2,100 people in Milizac-Guipronvel, Brittany, France. It discharges treated effluent near the coast of the Finistère department.
Milizac Treleon is a municipal wastewater treatment plant located in Milizac-Guipronvel, a commune in the Finistère department of Brittany, France. The plant serves a population of approximately 2,100 residents and operates with secondary treatment, which is the standard biological treatment required under European regulations for agglomerations of this size. As a plant in France, Milizac Treleon operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for all discharges from agglomerations with a population equivalent above 2,000. The plant's designed capacity is 3,000 cubic meters per day, and it currently discharges an average volume of 374.64 cubic meters per day, indicating ample capacity headroom. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the coastal waters of the Iroise Sea. The plant's proximity to the coast (within 10 km) means its discharge contributes to the nutrient and water quality dynamics of the sensitive marine environment, which supports diverse aquatic life and is an important area for fisheries and tourism.
Environmental context
The plant discharges into the local watershed that flows into the Iroise Sea, a coastal area of the Atlantic Ocean known for its rich marine biodiversity and strong tidal currents. The receiving waters support important commercial fisheries and are ecologically sensitive due to nutrient inputs from agricultural and urban runoff. The plant's secondary treatment helps reduce organic pollutants, but its coastal location requires careful management to prevent eutrophication in the nearshore zone.
