LORRIS Wastewater Treatment Plant, Noyers, Centre-Val de Loire, France

LORRIS is an advanced wastewater treatment plant located in Noyers, within the Centre-Val de Loire region of France. It serves a population of approximately 2,925 people, classifying it as a small agglomeration under French and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the region's municipal wastewater infrastructure. 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 sensitive areas. With a designed capacity of 3,500 m³/day and an actual discharge volume of 521.81 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variability. The plant's advanced treatment likely includes nutrient removal to protect downstream water quality. The treated effluent from LORRIS is discharged into the local watershed, which ultimately drains into the Loire River basin. The Loire is one of France's major rivers, flowing into the Atlantic Ocean. The advanced treatment helps safeguard the ecological health of the receiving water bodies, supporting aquatic life and maintaining water quality for downstream communities.

The plant discharges into the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire is known for its diverse aquatic ecosystems, including migratory fish species such as Atlantic salmon and European eel. Advanced treatment at LORRIS helps reduce nutrient loads, protecting the river from eutrophication and supporting biodiversity in this ecologically significant watershed.
