Aquifers are a vital element in the integrated and sustainable management of water resources. The European water research project DESSIN, which ended in 2017, has demonstrated that the injection of pre-potable water into aquifers can improve the economic and environmental sustainability of groundwater recharging.
The technique has been trialled for 18 months by Cetaqua (Water Technology Centre, Spain) on one out of 4 an experimental sites at the Sant Joan Despí DWTP (operated by Aigües de Barcelona). Results showed a positive impact on the quality and quantity of water in the Baix Llobregat aquifer, while allowing surplus water from the drinking water treatment process to be stored for subsequent extraction in periods of shortage. A tool developed during the project helps to integrate the technique with other innovative solutions in the integrated management of water resources, while evaluating its impact on ecosystems and the services that they provide us with (ESS).
