Sanitation Plan for the Arousa Estuary
Spain
The estuaries of Galicia are one of the economic drivers of the region, not just for their natural and tourist value, but also for fishing, especially shellfish. These are habitats with important marine dynamics and are very sensitive to pollution degradation.
Using hydraulic models allows us to know the operation of current systems and propose improvement actions
Augas de Galicia, the body responsible for water management in the area, develops programs to identify and manage sources of pollution at these locations. In this context, and after a first phase of the identification and digital modelling of the existing network (over 420 km modelled), improvement actions were proposed to ensure the sustainability of the different uses present in the estuary.
Knowing of the sanitation system and its impact on the marine ecosystems has set the stage for promoting the preservation of the natural environment, while ensuring the much-needed economic activity of the region.
