Assessment of a new pre-treatment device for removing solids and contaminants from stormwater runoff
EF 2024-25
Résumé
As areas become more urbanized, infrastructure such as buildings and impermeable surfaces including roads and parking lots replace natural undeveloped areas. This leads to increased stormwater runoff, flooding, and more harmful pollutants being delivered to surface water bodies. The concept of stormwater management was developed to combat the effects caused by the increase in stormwater runoff, but in some cases, traditional stormwater management infrastructure (e.g., wetlands and stormwater ponds) are insufficient in countering the effects. As a result, there has been a shift to other low-impact stormwater management infrastructure (e.g., bioretention systems, green roofs, permeable pavement) that can treat stormwater more locally and nearer the source. This project will provide a holistic field assessment of a new pre-treatment device, EnviroBasin, for removing solids and pollutants from stormwater immediately after runoff, thereby improving the functioning and longevity of downstream stormwater control measures. For this project, an EnviroBasin, which consists of a removable mesh filter installed in a pre-cast sumped catch basin with a submerged outlet baffle, will be installed adjacent to an arterial road in London, Ontario. Extensive field monitoring will be performed to assess its performance for treating stormwater runoff across numerous storm events over all seasons, with varying weather conditions, intensities and contaminant loadings to the EnviroBasin. In addition, monitoring will be conducted between runoff events to assess the potential release of nutrients and metals from sediments captured in the sump, and how this release may vary seasonally including the effects of winter road de-icing salts. The findings from this project will provide stormwater practitioners and government agencies with insights on the performance, including the operational and maintenance requirements, of at-source pre-treatment stormwater devices, which will become more and more adopted and deployed across Canada as urbanization increases.
