The project

LIFE Matrix: Safe water reuse

Towards the reduction of water stress

Matrix is a European project co-funded by the LIFE Programme that aims to demonstrate the technical, environmental and health feasibility of a Managed Aquifer Recharge (MAR) using reclaimed water in the Costa del Sol.

Using reclaimed water to face water stress

The LIFE Matrix project aims to address the water scarcity problem and aquifer overexploitation by combining two different techniques: MAR and Safety Plans. The solution is based on the infiltration of reclaimed water previously subjected to an additional treatment, which will contribute to the recovery of the good quantitative status of European groundwater bodies.
