SAINT MARTIN EN CAMPAGNE Wastewater Treatment Plant, Petit-Caux, Normandy

The SAINT MARTIN EN CAMPAGNE wastewater treatment plant is located in Petit-Caux, within the Normandy region of France. It serves a population of approximately 8,000 people, classifying it as a small to medium agglomeration under EU regulations. The plant is situated near the coast, within 50 km of the English Channel, and its operations are integral to the local wastewater management infrastructure. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000. The designed capacity of 1.00 m³/day suggests a treatment scale consistent with the population served. The regulatory framework ensures compliance with European standards for effluent quality. The plant discharges treated wastewater into the local watershed, which ultimately drains into the English Channel. This coastal discharge requires careful management to protect marine ecosystems, including sensitive habitats and species. The Normandy coast supports diverse aquatic life and is an important area for migratory birds and fisheries. The plant's role in reducing nutrient and pollutant loads is critical for maintaining water quality in the downstream environment.

The plant's treated effluent flows into the local river system, which drains into the English Channel near the Normandy coast. This coastal zone supports diverse marine life, including fish stocks and migratory bird populations. The proximity to the sea means that nutrient and pollutant discharges must be carefully managed to prevent eutrophication and protect sensitive coastal habitats.
