Green Infrastructure: Constructed basins (ponds and wetlands) can be an important tool for retention and detention of stormwater runoff. Because they utilize vegetation, bioretention practices provide additional benefits, including cleaner air, carbon sequestration, improved biological habitat, and aesthetic value.
Constructed basins (wet ponds and stormwater wetlands) are designed to retain solids and associated pollutants by settling. A typical method for assessing the performance of constructed basins is therefore measuring and comparing pollutant concentrations at the influent and effluent.
Case studies include the following.
