Overview
LA FERTE MACE wastewater treatment plant serves Magny-le-Désert in Normandy, France, treating wastewater for approximately 8,930 people. The plant operates under the EU Urban Waste Water Treatment Directive.
LA FERTE MACE is a wastewater treatment plant located in Magny-le-Désert, within the Normandy region of France. It serves a population of approximately 8,930, classifying it as a small to medium agglomeration under EU regulations. The plant is situated in a rural area near the town of La Ferté-Macé. As a French facility, the plant is subject to 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. It is expected to meet the regulatory standards for its population tier. The treated effluent from LA FERTE MACE is discharged into local watercourses that eventually drain into the Atlantic Ocean via the Loire River basin. The plant plays a key role in protecting the region's water quality, supporting aquatic life in downstream rivers and contributing to the ecological health of the Normandy countryside.
Environmental context
The plant discharges into local streams that feed into the Mayenne River, a tributary of the Loire River, which flows into the Bay of Biscay (Atlantic Ocean). The downstream environment supports diverse freshwater and estuarine habitats, including fish spawning grounds and migratory corridors for species such as Atlantic salmon. The region's agricultural landscape means nutrient management is important to prevent eutrophication in receiving waters.

The plant serves approximately 8,930 people, classifying it as a small to medium agglomeration under EU wastewater regulations.
Treated effluent is discharged into local watercourses that flow into the Mayenne River, a tributary of the Loire River, ultimately reaching the Atlantic Ocean.
As a French plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size and may require advanced treatment if discharging into sensitive areas.
For agglomerations between 2,000 and 10,000 population equivalent, the EU directive requires secondary treatment (biological treatment). French plants typically use activated sludge or similar processes to meet effluent quality standards.
