PRETX

Extend the operating life and reduce the maintenance burden of biofiltration systems by filtering out trash and debris at the inlet with PRETX.

PRETX enables the simplified maintenance of biofiltration systems at the inlet in an accessible location with no special equipment required. The absence of a pre-filter may allow trash and debris to prematurely clog the biofilter media or infiltration bed. The rapid accumulation of trash and debris can require frequent maintenance for aesthetics in high loading land uses and reduce the infiltration rate of filtration media. Installation is simple and would be comparable to common catch basins and grates and requires no special tools or training.

PRETX is made of pre-cast concrete, HDPE, and stainless steel and is resistant to rust and rot from corrosive winter runoff.
