BRESSOLS LACTEL Wastewater Treatment Plant, Bressols, Occitanie

BRESSOLS LACTEL is an advanced wastewater treatment plant located in Bressols, a commune in the Tarn-et-Garonne department of Occitanie, southern France. The plant serves a population of around 2,350 people, reflecting its role in treating municipal wastewater for a small agglomeration. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants discharging into sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 13,600 m³/day, indicating it is sized to handle peak flows and future growth. The treated effluent is discharged into the local watershed, which ultimately drains into the Tarn River and then the Garonne River, flowing toward the Atlantic Ocean via the Gironde estuary. The plant's advanced treatment helps protect the ecological health of these water bodies, supporting aquatic life and water quality downstream.

The plant discharges into the Tarn River basin, which flows into the Garonne River and eventually reaches the Atlantic Ocean via the Gironde estuary. This watershed supports diverse aquatic ecosystems, including fish species such as Atlantic salmon and European eel. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters.
