Protecting Biofiltration Systems at the Inlet
Capture sediment, debris, and floatables before they impact downstream treatment performance.
Solving Engineers’ Biggest Challenges
- Need to reduce biofilter maintenance? PRETX-LT captures trash and debris at the inlet, helping prevent clogging and reducing maintenance frequency.
- Need an easy-to-maintain solution? PRETX-LT is designed for simple upkeep using standard vacuum truck equipment.
- Need to extend the lifespan of biofiltration systems? By preventing premature clogging of filtration media, PRETX-LT helps maintain infiltration rates and system performance.
- Need a durable, long-lasting solution? Precast concrete and galvanized steel components are designed for harsh runoff conditions.
- Need flexibility in installation? PRETX-LT is designed for retrofit or new construction applications.
How PRETX-LT Works
PRETX-LT uses a multi-stage treatment process to remove pollutants at the point of entry, protecting downstream biofiltration systems and extending their operational life.
- Debris Grate Screens out leaves, trash, and large debris.
- Floatable Baffle Deflects and traps floatables and lightweight materials.
- Sediment Weir Promotes settling of suspended solids.
- Discharge to Biofilter Pretreated water flows to the biofiltration system for final treatment and infiltration.
The PRETX-LT Advantage

Engineered Multi-Stage Pretreatment
PRETX-LT uses multiple treatment mechanisms in a compact, inlet-based system designed to remove debris, floatables, and sediment before runoff enters downstream treatment infrastructure.
- Debris Grate – Screens out leaves, trash, and large debris.
- Floatable Baffle – Deflects and traps floatables and lightweight materials.
- Sediment Weir – Promotes settling of suspended solids.
- Discharge to Biofilter – Pretreated water flows to the biofiltration system for final treatment and infiltration.
Protect Biofiltration Performance Before Runoff Reaches the Media
PRETX-LT helps engineers, owners, and municipalities reduce maintenance demands while improving long-term green infrastructure performance.
