On October 17, 2025, at the XI. Soós Ernő International Scientific Conference – Water and Wastewater Treatment in the Industry 2025 (Zalakaros), our doctoral student Reham Saleh Mohammad presented “Treated wastewater reuse for sustainable agriculture based on the MAR approach – Kiskunfélegyháza, Hungary.” The talk—based on an ongoing Hungarian case study—outlined how treated wastewater (TW) could become a viable input for Managed Aquifer Recharge (MAR; targeted subsurface replenishment). Based on the data gathered so far and the local hydrogeological context, injection-based MAR appears promising.
Take-home message: with responsible pre-treatment, targeted MAR design, and transparent risk management, treated wastewater can become a strategic water reserve—especially where water security is threatened by drying trends and highly variable recharge.
This approach directly supports the goals of the ÉMNL – National Multidisciplinary Laboratory for Climate Change (RRF-2.3.1-21-2022-00014) on water retention and the safe, climate-adaptive replenishment of groundwater resources, and aligns with the ClimEx-PE ( 2023-1.2.2-HE_PARTNERSÉG-2023-00005) (Water4All – 101060874) project’s NaBa-MAR perspective, which examines the landscape-scale effects of local interventions.
