Tallard Wastewater Treatment Plant, Tallard, France | Secondary Treatment Facility

The Tallard wastewater treatment plant is located in the commune of Tallard, within the Hautes-Alpes department of the Provence-Alpes-Côte d'Azur region in southeastern France. The plant serves a population of approximately 3,483 residents, classifying it as a small agglomeration under French and EU regulations. As a secondary treatment facility, the plant meets the minimum requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent above 2,000, which Tallard exceeds. The plant has a designed capacity of 3,333 m³/day and currently discharges 621.36 m³/day of treated wastewater. The treated effluent is discharged into a local watercourse that ultimately drains into the Durance River, a major tributary of the Rhône. The Durance River supports diverse aquatic life and provides water for irrigation and hydroelectric power in the region. The plant's operation helps protect the local watershed and downstream ecosystems from untreated pollution.

The Tallard plant discharges into a local stream that flows into the Durance River, a major alpine river in southeastern France. The Durance is a key tributary of the Rhône, supporting diverse aquatic habitats and providing water for agriculture and energy production. The plant's secondary treatment reduces organic pollutants and suspended solids, helping maintain water quality in this ecologically sensitive river system.
