Our System: In-Ground

Our popular in-ground design incorporates the existing native soil as the biofilter’s containment walls. These biofilters are built either directly into the excavated ground with the finished surface at grade level or raised above grade with sloping earth-berm walls. The rugged simplicity of this design is not only cost-effective but also aesthetically pleasing.

In-ground biofilters are not confined to a rectangular shape; in fact, quite the contrary. In-ground biofilters can be configured in any shape and can thereby take full advantage of previously unusable areas around existing storage tanks, medians, or any other structure.

A unique feature of the in-ground biofilter is the ability to grow a lush grass cover on the surface.
