Protecting Your Stormwater Control Measures

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

SOLVING ENGINEERS’ BIGGEST CHALLENGES

  • Need to reduce biofilter maintenance? PRETX captures trash and debris at the inlet, preventing clogging and reducing maintenance frequency.
  • Need an easy-to-maintain solution? PRETX is designed for simple upkeep using standard vacuum trucks and a pressure washer—no special equipment or training required.
  • Need to extend the lifespan of biofiltration systems? By preventing premature clogging of filtration media, PRETX helps maintain infiltration rates and prolongs system performance.
  • Need a durable, long-lasting solution? Constructed from pre-cast concrete, HDPE, and stainless steel, PRETX is resistant to rust, rot, and corrosive runoff.
  • Need flexibility in installation? PRETX is available in curb and drop inlet configurations, making it adaptable for both new and retrofit stormwater management projects.

Biofilter Inlet Systems for Stormwater Pretreatment

Keep your biofilters, bioretention and subsurface infiltration systems clean.

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 media filtration rate. 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.

WHY DO ENGINEERS AND LAND DEVELOPERS NEED PRETX?

Engineers and land developers need PRETX because it provides an efficient, cost-effective solution for maintaining biofiltration systems while reducing long-term maintenance burdens. By capturing trash and debris at the inlet, PRETX prevents premature clogging of biofilter media and infiltration beds, ultimately extending the lifespan of these systems. This reduction in maintenance needs results in a rapid return on investment, typically within one to two years, particularly in areas with high debris loads such as commercial and residential developments.

PRETX simplifies maintenance by ensuring that debris removal occurs at an accessible location, eliminating the need for deep excavation or specialized labor. Unlike traditional systems that may require complex cleaning procedures, PRETX can be maintained using standard vacuum trucks and a pressure washer, making routine upkeep straightforward and cost-efficient.

Additionally, the durability of PRETX makes it a reliable long-term solution. Constructed from pre-cast concrete, HDPE, and stainless steel, it is highly resistant to rust and rot, even in environments exposed to corrosive winter runoff. Its adaptability also allows for easy integration into both new and retrofit installations, with configurations available for curb and drop inlets. By improving the efficiency of biofiltration systems, reducing maintenance demands, and ensuring long-lasting performance, PRETX is an essential tool for engineers and land developers seeking sustainable and effective stormwater management solutions.

NO SPECIAL EQUIPMENT NECESSARY.

Maintenance of PRETX is simple and utilizes standard vacuum trucks for catch basin cleaning; simply remove the inspection cover and remove debris by use of pressure washer and vacuum.

PRETX has a 1-2 year return on investment by reduction of biofilter maintenance if used in locations with moderate to high trash and debris load such as commercial and residential areas.

Applications

  • Bioretention Systems
  • Bioswales & Biofiltration Systems
  • Infiltration Trenches
  • Bioswales

Stacking Up The Benefits

  • PRETX is available in two models that manage most biofilter inlet configurations: Curb and Drop.
  • PRETX Curb is for edge of pavement runoff at a curb cut in replace of a stone spreader.
  • PRETX Drop is for use as a drop inlet configuration along a curb line and would be installed with a standard drop inlet grate.
  • PRETX is sized to pretreat water quality flows and bypass larger. This keeps the size of the system smaller than if it were to pretreat larger flows that have minimal trash and debris.
  • PRETX can be used both in retrofit or new installations.
