Overview
MEJANNES LE CLAP wastewater treatment plant serves the Cabiac area in Occitanie, France. It provides advanced treatment for a population of 1,831 with a designed capacity of 2,000 m³/day.
MEJANNES LE CLAP is a wastewater treatment plant located in Cabiac, within the Occitanie region of southern France. The plant serves a population of approximately 1,831 people and has a designed capacity of 2,000 cubic meters per day. It is situated in a rural area near the Cèze River basin, contributing to local water quality management. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant's discharge volume is reported at 326.65 m³/day, indicating it operates well below its designed capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Cèze River and then the Rhône River before reaching the Mediterranean Sea. The region is known for its karst landscapes and sensitive aquatic ecosystems, making advanced treatment important for protecting downstream water quality and biodiversity.
Environmental context
The plant discharges into the Cèze River basin, a tributary of the Rhône River, which flows into the Mediterranean Sea. The Cèze River supports diverse aquatic life and is part of a region with sensitive karst aquifers. Advanced treatment helps minimize nutrient loading and protects downstream ecosystems, including coastal waters of the Gulf of Lion.
