To treat stormwater pollution, we incorporate trees and shrubs into our Filterra design to create a cost effective solution for your stormwater projects.
Best Value. Filterra offers the most cost effective stormwater treatment system featuring low cost, and easy installation and maintenance.
Regulatory Compliance. University of Virginia testing confirmed that Filterra meets or exceeds federal and state regulatory requirements for pollutant removal.
Aesthetics. Landscaping enhances the appearance of your site making it more attractive while removing pollutants.
Maintenance Support. A one year maintenance agreement is included with the purchase of every unit.
Versatility. Filterra is used for both new construction and urban retrofits. Filterra works well in many applications, including:
Design Support. Our engineers can assist you with all aspects of each Filterra application, including flora selection and sizing.
Adaptability. Filterra can be used alone or in combination with other Best Management Practices (BMPs).
Selection. Filterra is available in various configurations to meet both standard and unique site conditions. It is well suited for ultra-urban environments, providing high removal efficiency for many toxic substances such as petroleum and heavy metals.
Expected Pollutant Removals
(Ranges varying with particle size, pollutant loading and site conditions)
Information on pollutant removal efficiency of the filter soil/plant media is based on more than three-years of lab and field studies performed by the Civil Engineering Department at the University of Virginia. See Whitepaper for more details.
