SPELBasin 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
SPEL Basin
Effective at removing a wide range of stormwater pollutants.
  • Commercial
  • Industrial
  • Residential

Can be used in a wide range of configurations for new construction and retrofit applications.

Because of its availability to accept variable pipe sizes or runoff directly from the built-in curb or drop inlet, this system can be used in most situations, regardless of site constraints.

A pre-filter chamber eliminates the need for maintenance to be undertaken in the Biorention chamber.

The Modular Bioretention System can be installed downstream of retention systems.
