Overview
NIVILLAC is an advanced wastewater treatment plant in Nivillac, Bretagne, France, serving approximately 3,951 people. It discharges 704.85 m³/day of treated wastewater and is located within 10 km of the coast.
NIVILLAC is an advanced wastewater treatment plant located in Nivillac, a commune in the Morbihan department of Bretagne, France. The plant serves a population of approximately 3,951 people, reflecting its role as a small-scale municipal facility in a rural coastal area. 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. With a designed capacity of 3,583 m³/day and a current discharge volume of 704.85 m³/day, the plant operates well within its capacity, ensuring effective treatment of local wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Vilaine River estuary. The plant's proximity to the coast (within 10 km) makes its advanced treatment level particularly important for protecting the sensitive marine environment and supporting the ecological health of the region's coastal waters.
Environmental context
The plant discharges into the Vilaine River basin, which flows into the Atlantic Ocean near the Morbihan Gulf. This coastal area supports diverse marine life, including fish nurseries and migratory bird populations. The advanced treatment level helps minimize nutrient loading and protects the sensitive estuarine ecosystem from eutrophication.
Frequently asked questions
The NIVILLAC plant is located at D 176, Nivillac, in the Morbihan department of Bretagne, France. It serves the local community of approximately 3,951 people.
The plant has a designed capacity of 3,583 m³ per day and currently discharges an average of 704.85 m³ per day of treated wastewater, indicating it operates well below its maximum capacity.
The treated effluent is discharged into the local watershed, which flows into the Vilaine River and eventually reaches the Atlantic Ocean. The plant's advanced treatment ensures high-quality effluent to protect the coastal environment.
As a French wastewater treatment plant, NIVILLAC operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 2,000 population equivalent. The plant's advanced treatment exceeds these requirements.
For small agglomerations in France, secondary treatment is the standard under EU directives. However, plants near sensitive coastal areas often implement advanced treatment to reduce nutrient pollution and protect marine ecosystems, as seen at NIVILLAC.
