LA JONQUERA Wastewater Treatment Plant, la Jonquera, Catalunya

LA JONQUERA is a wastewater treatment plant located in la Jonquera, a town in the Alt Empordà region of Girona, Catalunya, Spain. The plant serves a population of approximately 8,949 people, placing it in the small agglomeration category under European Union classifications. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Spanish regulations typically mandate compliance with discharge standards set by the relevant water authority. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Mediterranean Sea via the Muga River or other nearby coastal streams. The Alt Empordà region is ecologically sensitive, supporting diverse aquatic life and agricultural activities. Proper treatment helps protect downstream water quality and the coastal environment.

The plant's treated effluent flows into the local river network, likely the Muga River or a tributary, which drains into the Gulf of Roses in the Mediterranean Sea. This coastal area supports important marine habitats and is a key area for tourism and fishing. The region's Mediterranean climate means water resources are seasonally stressed, making effective wastewater treatment critical for maintaining ecological balance and preventing nutrient enrichment in coastal waters.
