Plougonven Goasvale Wastewater Treatment Plant, Plougonven, Bretagne, France

Plougonven Goasvale is an advanced wastewater treatment plant located in the commune of Plougonven in the Finistère department of Bretagne, France. The plant serves a population of 1,602 and has a designed capacity of 4,000 m³ per day, with an average discharge volume of 285.79 m³ per 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. As a French facility, it operates under national regulations transposing the directive, ensuring high effluent quality standards. The treated effluent is discharged into the local watershed, which ultimately drains into the English Channel via the Morlaix River estuary. The surrounding area is ecologically sensitive, supporting diverse aquatic life and contributing to the health of the coastal marine environment.

The plant discharges into the local river system that flows into the Morlaix River and then into the Bay of Morlaix, part of the English Channel. This coastal zone supports diverse marine habitats, including seagrass beds and nursery areas for fish. The advanced treatment helps protect downstream water quality and the ecological balance of the estuary.
