VUB investigates whether treated wastewater via underground infiltration can help agriculture

In recent years, Flanders has been confronted with long and intense periods of drought.

The soil is getting wetter and the groundwater level is rising. In this way, the crops receive sufficient moisture, which could benefit the harvest.
