Significant
cost savings

The EnviroPod™ LittaTrap™ is a modular and versatile inlet filter device designed to capture trash, debris, sediment and other pollutants conveyed in stormwater
runoff, meeting water quality objectives and regulations.

Lightweight and structurally robust, with an 8-year warranty, the LittaTrap™ is designed to fit a range of catch basin structures, and can also be customized
to meet site-specific pollutant removal requirements, such as sediment or
plastic pellets.

Easy to install and maintain, the LittaTrap™ is North America's leading stormwater Catch Basin Filter.

LittaTrap Catch Basin Filter
How it works

Installed inside the stormwater catch basin on engineered structural brackets. The LittaTrap™ patented design captures and  stores gross solids caught up in the stormwater runoff.

1

As stormwater runoff flows into the catch basin through a grate or curb entry, the runoff will enter the LittaTrap™ system.

2

The LittaTrap™ basket captures the pollutants caught in the runoff and allows the water to pass through to the outlet pipe. When maintenance is required, the basket can simply be lifted out and emptied by hand or contents can be removed by a vacuum inductor truck.

3

Once the basket is full or during high flows, overflow is released through the overflow bypass apertures in the frame assembly.

Features

Superior pollutant removal with high hydraulic efficiency

The EnviroPod™ LittaTrap™ catch basin filter is a proven, robust technology that can be applied in varying applications. Designed to target trash, plastic, and other pollutants to ensure compliance with stormwater quality requirements, the LittaTrap™ has a high capacity pollutant storage with high hydraulic efficiency.

Full capture of trash, plastic, debris

Full capture of pollutants and with the interchangeable performance liners ranging from 100 to 1000+ micron pore size, the LittaTrap™ can be tailored to a site-specific solution.

Easy to install and fits existing infrastructure

Often the most practical solution for retrofits as it requires no alterations to the drainage network.

Easy maintenance with minimal cost and effort

Easy to maintain with no confined space entry.

Supported by an eight-year limited warranty

Designed with engineered plastic and structurally robust, the LittaTrap™ is supported by a comprehensive 8 year warranty.

Independently tested

Independently trialled and tested by municipalities and with over 50,000 units installed worldwide the EnviroPod™ LittaTrap™ is the most specified filter insert available today.

Modular Design for Flexibility

The LittaTrap™ system is a universal fit with seal kits and adaptors to fit any catch basin. Grate, Manhole and Combination configurations available in multiple sizes.

Pre-treatment for downstream infrastructure

Protect downstream infrastructure by including the LittaTrap™ as part of a treatment train.

Meets Regulatory Compliance

Meets and adheres to water quality objectives and regulations. To meet Full Capture requirements please see LittaTrapFC

Enhanced particle capture with performance liners

The performance of the LittaTrap™ can be enhanced by the use of liners. The liners are easily attached to the LittaTrap™ basket and allow the capture of finer particles, and pollutants of concern such as plastic pellets and TSS.

Inlet Configurations

LIttaTrap drain grate with drain filter

Grate Inlet

The innovative design of the LittaTrap™ allows for installation across a wide range of grate inlets. No two catch basins are the same which makes other catch basin inserts difficult or expensive to install. The LittaTrap™ has standard sizes and flexibility using simple-to-use seal kits allows for professional and high-performance installations.

LittaTrap FC Inlet Filter Curb Entry

Curb Inlet

The advantage of using a LittaTrap™ is the modular design. This allows for standard units to be installed on any curb inlet infrastructure, despite the field constraints.

Manhole inlet filter

Manhole Inlet

The LittaTrap™ can be installed easily within a range of round stormwater infrastructure. We use a bracket that is as easy to install as the LittaTrap™ itself. The round seal kits can then be used to finish off the installation that looks professional and provides optimal flow of water into the system.

Installation

Simple Installation

The LittaTrap™ is designed to be simply installed into the catch basin. The modular design allows for flexibility with the install and has a number of different configurations.

Measure & assess catch basin

Before installing a LittaTrap™, the catch basin needs to be assessed and measured to gauge suitability. Follow the step-by-step guide to ensure the catch basin is measured accurately.

Attach brackets & install Filterbox

Follow guidelines in instruction guides and video

Insert Filterbag & performance liner if required
