Filtrexx® Rain Garden is a Low Impact Development (LID) management practice that combines native soil, compost, plants, and beneficial microorganisms to filter, retain, and infiltrate storm water runoff from developed sites. Filtrexx® Rain Gardens are designed to decentralize and distribute site storm water to reduce off-site storm water volume, peak flow rate, and pollutant discharges. Filtrexx® GrowingMedia™ is an important component of a successful Filtrexx® Rain Garden installation, while Filtrexx® Treatment Train technology can be used to target specific storm water pollutants, such harmful bacteria, nutrients, heavy metals, and petroleum hydrocarbons.
Filtrexx® Rain Garden can be installed on virtually any site utilizing a variety of design goals. Filtrexx® Rain Gardens are recommended where:
Post-development hydrology must mimic the pre-developed or natural site condition
LID, Green Infrastructure, or Green Building practices are preferred or required
Reduction of site runoff volume, peak flow rate, and/or pollutant load discharges is desired or required
On-site treatment of storm water in desired or required
Aesthetic, land-based storm water treatment is desired
Storm water treatment must use natural design elements, protect or restore wildlife habitat, or restore ecosystem services
Land improvement, function, and real estate value are important
Reduced ecological footprint is desired, including use of materials that are: recycled, biobased, locally manufactured, indigenous, and carbon neutral.
