This scientific opinion paper discusses the key topics of the European Commission’s Proposal for a Recast Urban Wastewater Treatment Directive. It shows how the proposed changes could affect wastewater treatment in Germany and highlights further refinement needs.

In general, the proposal of the revised UWWTD is endorsed. The clear shift from basic wastewater collection and treatment to efficient wastewater management will have a positive influence on various environmental targets. It will also reduce the impact of wastewater treatment on the receiving water bodies as well as the impact of climate change on both, our cities, and the environment.
