Print Case Study
AECOM - Seattle
Washington State and local stormwater regulations require stormwater quantity and quality measures to be used to reduce downstream flooding and pollutants. Some of the runoff was treated and detained in traditional bioretention cells. However, due to space limitations, not all of the runoff could be treated by traditional methods.
The Engineer of Record reviewed several proprietary treatment systems, but the shallow nature of the site and limited space restricted what could be used. The Filterra Bioscape was the perfect solution for treating the additional runoff. While it operates similar to traditional bioretention, Filterra's high-flow media allows for a reduction in footprint of
up to 95% versus traditional bioretention practices. The Filterra Bioscape utilizes all of the Filterra bioretention system components without the concrete structure, allowing for multiple inlets and installation directly into a basin. The 700-square-foot Filterra Bioscape provided a landscape-based solution that blended seamlessly with the other bioretention facilities on the site.
Contech provided full engineering support and supervised the installation to ensure proper system functionality.
