Short summary

Global hydrological models are applied at high spatial resolutions to quantify water availability and evaluate water scarcity mitigation options. Yet, they mainly oversee critical local processes. This paper presents and demonstrates the inclusion of wastewater treatment and reuse into a global hydrological model. As a result, model performance improves, and models consider treated wastewater as an alternative water source.
