Treatment Function in the Spotlight: How Bioretention Design Guidelines Address Water Treatment?

Year: 2026

Type: conference-paper

Abstract: Nature-based solutions (NBS) are infrastructure systems designed to manage stormwater while also meeting service goals such as improving ecosystems services and water quality. Design guidelines for each specific NBS should include comprehensive information on the strategies and methodologies necessary to achieve the designated service objectives, thereby ensuring their successful realization. Herein, we evaluated bioretention design guidelines from different parts of the world to examine how various practitioners recommend achieving stormwater quality improvement objectives, in particular by reviewing the water quality advice recommended regarding filter media. Among the seven guidelines reviewed, one did not provide any explicit statements regarding the targeted pollutants for removal. Furthermore, only 3/7 guidelines offered recommendations for selecting filter media materials based on pollutant removal considerations, and only 1/7 guidelines tied the calculation of media depth to water quality. Further reviews of these guidelines will evaluate the planting selection, ponding depth, water quantity volume estimation, and their effect on water quality.
