SPEL Basin  

SPEL Basin

SPEL Basin Modular Bioretention System is a highly advanced stormwater filtration system. Its size and capacity make it ideal for stormwater treatment trains that require high pollutant reduction in a small footprint. It can be used in place of standard catch basin structures, rain gardens, bioretention cells and media filters.

As a self-contained treatment train, it incorporates the following treatment components:

  • screening
  • hydrodynamic separation
  • media filtration
  • bioretention filter

The bioretention filter is an enhanced sub surface flow vegetated wetland with a special blend of sorptive media.

The Modular Bioretention System’s treatment train approach makes this system very effective at removing a wide range of stormwater pollutants.
