Overview
CADAUJAC wastewater treatment plant serves Cadaujac, Nouvelle-Aquitaine, France. It is an inland facility designed for a capacity of 1.00 (likely in thousand m³/day or PE), serving a population of 11,211.
The CADAUJAC wastewater treatment plant is located in Cadaujac, a commune in the Gironde department of Nouvelle-Aquitaine, southwestern France. It serves a population of approximately 11,211, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from the coast, and its treated effluent likely discharges into a local watercourse within the Garonne River basin. As a French facility serving over 10,000 people, the plant is subject to the EU UWWTD, which mandates secondary treatment as a minimum. For agglomerations of this size, secondary treatment is required unless the receiving waters are designated as sensitive areas, in which case more stringent tertiary treatment may be necessary. Indicating a scale appropriate for its service population. Given its location in the Garonne watershed, treated wastewater likely flows into a tributary of the Garonne River, which ultimately drains into the Gironde estuary and the Atlantic Ocean. The Garonne basin supports diverse aquatic life and is an important ecological corridor in the region. Proper treatment helps protect downstream water quality and the sensitive estuarine environment.
