Biofiltration Systems

StormVault Biofiltration - High Performance, Low Impact Development Solutions for Urban Areas

The StormVault Biofiltration System is a simple and highly versatile stormwater treatment solution. Through physical and chemical filtration, adsorption, and biological processes, StormVault Biofiltration efficiently removes total suspended solids, metals, nutrients, oil, and grease from stormwater runoff to meet water quality standards as a low impact development best management practice. With specially engineered filter media, the system can treat higher flows than conventional biofiltration units, allowing for a smaller footprint size and lower overall costs. Standard configurations include planter boxes, tree boxes, tree wells, and underground vaults. All configurations can be deployed with a traditional closed bottom or an open bottom to allow infiltration and promote groundwater recharge. Units can be supplied for inline, open grate, or curb inlet applications.

How It Works

  1.  Inlet –  Inlet configurations include grated, piped, direct curb inlet and curb inlet chamber
  2. Internal Bypass Pipe – Conveys excess flow past the treatment chamber. Note: External Bypass configurations available
  3. Mulch Stabilization Layer – Captures large trash and debris, protects media from scour and retains water for vegetation
  4. Engineered Media – Inorganic components remove TSS and metal. Organic components remove nutrients and facilitate biological uptake, which supports plant life
  5. Bridging Stone – Allows for even drainage and protects the effluent pipe from clogging
  6. Perforated Underdrain Pipe – Conveys treated flow to storm drain systems
