PANTANS DE MONTBARBAT Wastewater Treatment Plant, Maçanet de la Selva, Catalunya

PANTANS DE MONTBARBAT is a wastewater treatment plant located in Maçanet de la Selva, in the province of Girona, Catalunya, Spain. It serves a population of 1,341 and has a designed capacity of 3,687 m³/day, with an average discharge volume of 385.06 m³/day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. As a small agglomeration, it meets the directive's requirements for secondary treatment before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea via the Tordera River basin. The region's coastal environment supports diverse aquatic life, and proper treatment helps protect downstream ecosystems and recreational waters.

The plant discharges into the Tordera River basin, which flows into the Mediterranean Sea near Blanes. This coastal area supports diverse marine and coastal ecosystems, including seagrass meadows and fish nurseries. The secondary treatment ensures that nutrient and pollutant loads are reduced before reaching sensitive coastal waters.
