Portugal and, in particular, Algarve suffer from high water stress. In addition, in the current context of vulnerability to climate change, water availability demands timely planning of solutions for the storage, treatment, and rational and efficient use of water, in a region with a wide range of seasonal consumption and long periods of scarcity. In this context, the efficient and sustainable management of water resources, in terms of quantity and quality, in all sectors of economic activity, must be a priority.
The AquaLOOP project aims to develop an easy-to-apply solution for wastewater treatment regarding its reuse, thus promoting the circularity of the process. The project brings technological expertise, proof of concept of ambitious technology, pilot experience, and scientific researchers to provide an easy-to-apply effective and innovative global solution to ensure safe treated wastewater. The excellence of AquaLOOP lies in its multidisciplinary and multi-level approach: aiming to develop a new solution that will minimise the risks of reusing wastewater that could affect the environment and human health. For this aim, the solution proposed is a filter composed of a nanocomposite medium that will remove not only traditional pollutants but also emerging compounds, such as micropollutants, to produce wastewater for reuse. The project plans to engage stakeholders (from aquacultures, water companies, hotels, golf companies, agri-food companies, administrative institutions, etc.) to work together in the project towards the broader project goals. 
The challenge addressed by the present proposal is to provide a solution for regions vulnerable to water scarcity and depletion of water resources, where wastewater reuse can help minimising this threat.
