Pleyber Christ Milin ar Prat Wastewater Treatment Plant, Pleyber-Christ, Brittany

Pleyber Christ Milin ar Prat is an advanced wastewater treatment plant located in Pleyber-Christ, a commune in the Finistère department of Brittany, France. The plant serves a population of approximately 2,616 people and has a design capacity of 3,000 m³/day, with a current discharge volume of 466.69 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size (under 10,000 population equivalent) are generally required to provide secondary treatment, but the advanced level here indicates a higher standard, likely due to the sensitivity of the receiving environment. The plant discharges treated wastewater into the local watershed, which ultimately drains into the English Channel via the Morlaix River estuary. This coastal region supports diverse aquatic life and is ecologically sensitive, making advanced treatment important for protecting water quality and marine habitats.

The plant discharges into the local watershed that flows into the Morlaix River, which empties into the English Channel near the coast of Brittany. This coastal area supports diverse marine life and is important for fisheries and tourism. The advanced treatment helps protect the sensitive coastal ecosystem from nutrient pollution and other contaminants.
