PICQUIGNY SE Wastewater Treatment Plant, Picquigny, Hauts-de-France

PICQUIGNY SE is an advanced wastewater treatment plant located in Picquigny, a commune in the Somme department of Hauts-de-France, France. The plant serves a population of 2,054 and has a designed capacity of 4,000 m³/day, with a discharge volume of 366.43 m³/day. It is situated inland, more than 50 km from the coast. As an advanced treatment facility, PICQUIGNY SE goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, and advanced treatment is often implemented in sensitive areas to protect water quality. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Somme River and then into the English Channel. The Somme River basin supports diverse aquatic life and is an important ecological corridor in the region. The advanced treatment helps minimize nutrient loading and protects downstream ecosystems.

PICQUIGNY SE discharges into the Somme River basin, which flows into the English Channel. The Somme River supports diverse aquatic habitats and is an important migratory corridor for fish. Advanced treatment reduces nutrient pollution, safeguarding water quality in the river and the coastal zone.
