Poce Sur Cisse La Croix Saint Jean Wastewater Treatment Plant, Amboise, France

The Poce Sur Cisse La Croix Saint Jean wastewater treatment plant is located in Amboise, within the Centre-Val de Loire region of France. It serves a population of approximately 7,442 residents, classifying it as a small to medium agglomeration under French and EU regulations. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Compliance with national standards ensures adequate pollutant removal. The plant discharges treated effluent into the local watershed, which ultimately drains into the Loire River, one of France's major rivers. The Loire River flows into the Atlantic Ocean, supporting diverse aquatic ecosystems along its course. The plant plays a key role in protecting water quality in this ecologically significant river basin.

The plant's treated effluent enters the local water system, which flows into the Loire River, a major European river that drains into the Bay of Biscay (Atlantic Ocean). The Loire basin supports diverse aquatic life, including migratory fish species such as Atlantic salmon and European eel. Protecting water quality in this watershed is critical for maintaining ecological balance and supporting downstream communities.
