Overview
LALIN wastewater treatment plant serves Lalín, Galicia, Spain, treating wastewater for approximately 19,811 people. The plant operates under Spain's implementation of the EU Urban Waste Water Treatment Directive.
LALIN is a wastewater treatment plant located in Lalín, a municipality in the province of Pontevedra, Galicia, Spain. The plant serves a population of around 19,811, placing it in the medium agglomeration category under EU regulations. Its address is Paseo Pontiñas, As Queimadas, Filgueira, Lalín, O Deza, Pontevedra, Galicia. As a Spanish facility, LALIN is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the discharge enters sensitive areas. The plant is expected to meet these regulatory standards. The treated effluent from LALIN is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Ulla River basin. The plant plays a key role in protecting the water quality of the region's rivers and downstream coastal ecosystems, supporting both ecological health and human use of water resources.
Environmental context
LALIN discharges into the Ulla River basin, which flows through Galicia and empties into the Arousa estuary on the Atlantic coast. This estuary is ecologically sensitive, supporting diverse aquatic life including migratory fish species. The plant's treatment helps maintain water quality in this important coastal ecosystem.

The treated effluent from LALIN is discharged into the local watershed, which flows into the Ulla River basin and eventually reaches the Atlantic Ocean via the Arousa estuary.
As a Spanish plant, LALIN operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size and may require tertiary treatment if discharging into sensitive areas.
For agglomerations of around 20,000 people, the EU UWWTD requires secondary treatment (biological treatment). In Spain, this is typically achieved through activated sludge or similar processes, with possible nutrient removal if the receiving water is sensitive.
