Every year, Water Canada’s Water’s Next awards program honours the achievements and ideas of individuals and companies that successfully work to make a positive change to water in Canada and abroad.
Imbrium’s Filterra Bioretention System was one of four finalist in the Projects & Technologies – Stormwater category. Filterra is similar to bioretention in its function and application, but has been optimized for high volume/flow treatment and high pollutant removal. Its small footprint allows it to be used on highly developed sites such as landscaped areas, parking lots and streetscapes. Filterra is exceedingly adaptable and can be used alone or in combination with other BMPs.
At the heart of the Filterra system is Filterra engineered biofiltration media; a specified gradation of washed aggregate and organic material homogeneously blended under strict quality controlled conditions. Using data from independent, third-party studies including the University of Virginia (TARP), Herrera Environmental Consultants (TAPE), Terraphase Engineering (NJCAT), North Carolina State University (TAPE & TARP) and Geosyntec Consultants, the filter media has been optimized to operate under high flow rates while maintaining pollutant removal performance. Filterra media is tested for hydraulic functionality, fertility, and particle size distribution to ensure uniform performance.
Filterra media also supports a vegetation component with suitable hardiness for the local region consisting of grasses, shrubs, or trees that assist with the adsorption of pollutants with biological uptake/storage and pollutant consumption by microbes within the plant root zone.
Filterra systems have been installed in a number of locations throughout Canada, including the Kortright Centre for Conservation in Ontario, Aurora, ON, Brockville, ON, and in Abbotsford, BC.
Water Canada will announce the winners of the 2018 awards in Vancouver at the Water’s Next Awards Gala on June 20th at the Pinnacle Marriot hotel as part of the 9th annual Canadian Water Summit. Water Canada will also share their stories in the July/August issue of the magazine.
