Water Solutions

18 months SUBSOL, intermediate evaluation of project results

Related Work Package: 1.1, 1.2, 1.3, 2.1, 2.2, 2.3, 2.4, 3.1, 3.2, 3.3, 4.1, 4.2, 4.3, 4.4

During the first day of the meeting organized by the Geological Survey of Denmark and Greenland (GEUS) the Consortium Partners together with members of the Project Advisory Committee (Enrique Fernández Escalante and Andrew Hughes) discussed the results of the first half of the project on Subsurface Water Solutions (SWS) as well as the challenges for the next and final 18 months of the project.

In short, we concluded that the successful implementation of full scale SWS references in SUBSOL and the ongoing demonstration of SWS at the four replication sites in  Denmark, Greece, The Netherlands and Mexico fully support market uptake of SWS as robust measures to secure freshwater supply and to enable water reuse in water scarce areas worldwide. Besides technically facilitating water reuse, there is a growing awareness that the subsurface may also play a key role in the public acceptance of water reuse.


Breakout session.

Within SUBSOL a flexible web-based SWS knowledge environment is developed to support future users in applying SWS. The Knowledge environment includes a knowledge database, a marketplace and a toolkit with operational tools such as an online data monitoring dashboard to optimise SWS application and a location identification tool for SWS wells. Several elements of the knowledge environment have already been developed and will be tested by the SUBSOL partners in the next months. The SWS knowledge environment will be linked to initiatives and web-based platforms to secure application after the project lifetime.

The successful implementation of SWS strongly depends on awareness among regional stakeholders. Within SUBSOL a number of participatory Technology Assessments have been carried out to increase awareness at replication sites. Based on initial market analyses in selected regions worldwide, missions to target regions show promising results for successful market uptake of SWS.



Subsol replication site Falster

The second day of the meeting included a visit to the SUBSOL replication site on Falster Island to experience the coastline and the experimental activities of GEUS to optimize the setup for SWS to secure the availability of freshwater to the populated coastal recreation area. Specifically, tracer experiments to identify water flows in the complex, fractured chalk aquifer were explained and discussed.
