VALGA Wastewater Treatment Plant, Ponte Valga, Galicia, Spain

VALGA is a wastewater treatment plant located in Ponte Valga, within the province of Pontevedra in the autonomous community of Galicia, Spain. The plant serves a population of approximately 6,262 residents, placing it in the small agglomeration category under Spanish and EU regulations. Its location near the Atlantic coast influences its operational and environmental context. As a Spanish facility, VALGA operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland agglomerations of this size. The regulatory framework ensures that discharges meet quality standards to protect receiving waters. The plant's treated effluent ultimately reaches the Atlantic Ocean via local rivers and the Ría de Arousa, a coastal inlet known for its ecological significance. The surrounding area supports diverse aquatic life and is important for regional fisheries and tourism. Proper treatment at VALGA helps maintain water quality in this sensitive coastal environment.

VALGA discharges into local watercourses that flow into the Ría de Arousa, a large coastal inlet on the Atlantic coast of Galicia. This estuary supports rich biodiversity, including shellfish beds and migratory bird populations. The plant's proximity to the coast means that treated effluent must meet stringent standards to protect marine ecosystems and human uses such as bathing and shellfish harvesting.
