Treatment wetlands in the framework of the revised European Union Urban Wastewater Treatment Directive 2024

Year: 2025

Type: review

Abstract: The revised European Union Urban Wastewater Treatment Directive 2024/3019 introduces significant changes to the urban wastewater management framework across the European Union. Among its most notable developments are reinforced requirements for nutrient removal, the treatment of micropollutants, the management of urban stormwater, and broader ambitions for energy neutrality and water reuse. In this context, nature-based solutions appear increasingly relevant. Treatment wetlands including vertical flow and hybrid and bioelectrochemical systems offer solutions aligned with these objectives. This article examines recent innovations in constructed wetlands and evaluates their potential role in fulfilling the goals of the new directive, especially for small-scale systems.
