Ourense Hosts the European ThermEcoWat Workshop on Thermal Waters

From October 20 to 22, 2025, the province of Ourense, in Galicia (Spain), became the European hub for sustainable thermalism. The ThermEcoWat project organized a workshop there, bringing together researchers, thermal spa managers, and local authorities from France, Spain, and Portugal.

Workshop Objective: Sharing and Testing Sustainable Solutions

The workshop aimed to:

  • present the preliminary results of the ThermEcoWat project, focused on the preservation of thermal waters in the face of climate change;

  • promote the exchange of best practices among European thermal territories;

  • test innovative solutions on-site for the management and energy valorization of thermal waters.

A Comprehensive Program Combining Conferences and Field Activities

The workshop included:

  • Conferences and roundtables on thermal source resilience and climate adaptation strategies;

  • Technical visits to the main thermal spas of Ourense, such as A Chavasqueira and As Burgas, as well as the University of Vigo campus, to observe geothermal applications and heat reuse projects;

  • Transnational working groups, where researchers and local stakeholders exchanged practices and identified transferable solutions for other territories.

A Mobilized European Consortium

The event brought together:

  • BRGM experts (France) and public geological centers from Spain and Portugal (ICGC, CN IGME CSIC, LNEG);

  • Local thermal operators and authorities from Portugal (Termalistur – Termas de São Pedro do Sul E.M. S.A) and Spain (Ajuntament de Caldes de Montbui – ES), emphasizing collaboration and co-design of sustainable solutions;

  • the Diputación Provincial de Ourense, which hosted and coordinated the workshop.

Why Ourense?

The province is an emblematic territory for thermalism:

  • rich in historical thermal springs;

  • a pioneer in the sustainable and innovative exploitation of thermal waters;

  • ideal for observing and testing climate adaptation strategies developed by ThermEcoWat on-site.

Outlook

This workshop represents a key milestone in the ThermEcoWat project:

  • lessons learned in Ourense will be integrated into the action plans for pilot sites in France, Spain, and Portugal;

  • they will enable the implementation of tools and methodologies to help thermal territories sustainably manage their water resources and energy potential;

  • it also prepares the dissemination of best practices to other European territories.
