QUART Wastewater Treatment Plant, Girona, Catalunya, Spain

QUART is a municipal wastewater treatment plant located in Girona, in the Catalunya region of Spain. The plant serves a population of approximately 3,800 people and operates under Spain's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard required by the EU directive for freshwater discharges from agglomerations of this size. With a designed capacity of 2,750 cubic meters per day and a current discharge volume of 654.93 cubic meters per day, the plant operates well within its capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The plant plays a key role in protecting the region's water resources and supporting the ecological health of downstream water bodies.

The plant discharges into the Ter River basin, which flows into the Mediterranean Sea near the Costa Brava. The downstream environment supports diverse aquatic life and is an important coastal ecosystem. The plant's secondary treatment helps reduce nutrient loads and organic pollutants, contributing to the protection of marine water quality.
