PLOUGUERNEAU Prat Menan, Plouguerneau

Overview

PLOUGUERNEAU Prat Menan is an advanced wastewater treatment plant in Plouguerneau, Brittany, France, serving approximately 4,200 people with a design capacity of 5,000 m³/day.

PLOUGUERNEAU Prat Menan is an advanced wastewater treatment plant located in Plouguerneau, in the Brittany region of northwestern France. The facility serves a population of around 4,200 residents and has a design capacity of 5,000 cubic meters per day, with a current discharge volume of approximately 749 m³/day. 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. This level of treatment is particularly important in sensitive coastal areas to reduce nutrient loads and protect marine ecosystems. The treated effluent is discharged into the coastal waters of the English Channel, near the Aber Wrac'h estuary. This area supports diverse marine life and is part of a region known for its rich biodiversity, including seabird colonies and intertidal habitats. The plant's advanced treatment helps safeguard the local marine environment from eutrophication and other pollution impacts.
