With the dry summer of 2018, the issue of water shortages also reached the Euregio Meuse-Rhine. In addition, cross-border nutrient fluxes and water quality are also a challenge in the Three-Countries Park, for example as a result of inadequate wastewater treatment or slurry exports.
The research project HypoWave is designed to study how treated and purified wastewater from households and sewage plants can be used for agricultural production in greenhouses. The feasibility study in the East Belgian municipality of Raeren shows promising results. Technical modules on wastewater treatment, reservoirs, cut-flower production in the greenhouse and production of energy wood fast-growing tree species – this combination could be economically profitable and improve water quality.
