Oral Topic 10 - Urban groundwater Parallel




While drilling the Barcelona Metro L9 line, around the Fondo station of Santa Coloma de Gramenet (Barcelona), was detected that groundwater temperature was found to be up to 55°C. No previous evidences of geothermal activity were known in that area. This geothermal spot is located under a dense urban area where the study of its hydrogeological and geothermal features is limited by urbanization.
In order to overcome this problem a study has being undertaken at local and regional scale. This allows studying the feasibility of a future energy exploitation of the geothermal resource, as well as, assessing its potential for future exploitation in this dense urban area. The objective of the regional study is to understand the dynamics of the system for justifying the geothermal anomaly identified.
Many different tasks have been performed to achieve this goal, as geological assessment, borehole drilling, geophysics, etc. This anomaly is attributed to a rise of deep groundwater through some tectonic structures, in a similar way to other geothermal zones of Catalonia (Spain). Integrating many of this information into numerical models of flow and heat transport will allow validating conceptual model and quantifying these potential resources.
