Overview
MAINTENON PIERRES wastewater treatment plant serves Pierres in Centre-Val de Loire, France. It treats wastewater for approximately 7,383 people under the EU Urban Waste Water Treatment Directive.
MAINTENON PIERRES is a wastewater treatment plant located in Pierres, within the Centre-Val de Loire region of France. The facility serves a population of around 7,383 residents, classifying it as a small to medium agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its operations are integrated into the regional water management infrastructure. As a French treatment plant serving fewer than 10,000 people, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC. This directive requires appropriate treatment based on the sensitivity of receiving waters. For agglomerations of this size, secondary treatment is typically mandated unless the discharge is into a less sensitive area. It complies with national and EU standards. The treated effluent from MAINTENON PIERRES is discharged into local watercourses that ultimately drain into the Seine River basin, which flows into the English Channel. The plant plays a role in protecting the water quality of the Eure River and its tributaries, supporting aquatic ecosystems and downstream water uses. Its location in an agricultural region underscores the importance of nutrient removal to prevent eutrophication.
Environmental context
The plant discharges into the Eure River watershed, a tributary of the Seine River. The Seine flows through Paris and into the English Channel, supporting diverse aquatic life and serving as a critical water resource. The region's agricultural activities make nutrient management important to prevent algal blooms in downstream waters. The plant's treatment helps maintain ecological balance in this sensitive river system.
