Overview
CASTELLANE CHEF LIEU is a municipal wastewater treatment plant serving Castellane, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
CASTELLANE CHEF LIEU is a wastewater treatment plant located in Castellane, a commune in the Alpes-de-Haute-Provence department of the Provence-Alpes-Côte d'Azur region, southeastern France. The plant serves a population of approximately 5,860 people, placing it in the small agglomeration category under 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 discharges into freshwater and estuaries from agglomerations of this scale. The directive also mandates appropriate treatment for sensitive areas, which may apply given the region's environmental context. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Verdon River, a tributary of the Durance River. The Durance flows into the Rhône River, which empties into the Mediterranean Sea. This water body supports diverse aquatic life and is part of a region known for its ecological sensitivity.
Environmental context
The plant discharges into the Verdon River basin, which feeds into the Durance River and then the Rhône River, eventually reaching the Mediterranean Sea. The Verdon is known for its turquoise waters and supports a variety of fish species, including the endemic Rhône streber. The downstream environment includes ecologically sensitive areas that benefit from proper wastewater treatment to maintain water quality.
