The Enviropod LittaTrap is  a patented catch basin basket that sits inside the stormwater drain and  prevents  trash and other debris carried by stormwater from entering the storm drain system.

The LittaTrap's mesh basket is designed to capture and retain 100% of plastic and other debris over 5mm. The basket has high hydraulic conductivity, lightweight and is structurally robust, designed with engineered inert plastic for a 25 year lifespan.

The LittaTrap basket can be enhanced by the addition of performance liners to capture smaller particles.


The patented design reduces the energy of inflowing water to capture total suspended solids (TSS) in the basket and sump below and the full capture of gross pollutants.The novel design maintains catch basin hydraulic conductivity and allows easy maintenance of the basket when full and also the sump below.

- Storage of captured dry gross pollutants
- High capacity pollutant storage
- Superior pollutant removal with high hydraulic efficiency
- Design flexibility – a range of sizes to fit most catch basins. Available in several standard sizes, ranging from 450 x 450mm up to 1200 x 1200mm, with custom design available.

Capture and retain all plastic and other litter over 5mm including cigarette butts

Low cost solution

Lowest cost treatment available No construction means low capital costs

Simple & easy maintenance

The LittaTrap has  improved H & S with the inclusion of four lifting handles on the basket - designed for safety. Lightweight basket , designed to be lifted by hand.

Independently tested

Independently trialled and tested by city councils throughout Australia and New Zealand and with the installation of over 50,000 units worldwide including North America, the Enviropod LittaTrap is the most specified and installed pit insert in Australasia.

(Independently tested by Auckland University, NZTA, Auckland Council, Tauranga City Council, University of South Australia.)

Easy to install & retrofit

Simple step-by-step install.
The new support bracket uses a cantilever mechanism to enable the system to be mounted from one gully pit wall; halving installation time.

Target site-specific pollutants

Using passive screening , the Enviropod LittaTrap can be customised to meet site-specific requirements with interchangeable performance liners ranging from 100 to 1000+ micron pore size

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.

Technical Documentation

Measuring a catch basin to install a LittaTrap

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..


Traffic control must be well planned when installing or inspecting a LittaTrap. All standard rules and regulations governing Traffic Control and Health & Safety while working on the road must be followed at all times. All potential hazards must be identified and control methods put in place prior to undertaking any activity.

Step-by-Step Guide

Ensure to follow the instructions when installing a LittaTrap.

Easy Maintenance

The LittaTrap is designed to be emptied by hand so it can be easily cleaned by site owners or maintenance crew without the need for vacuum inductor trucks ( unless this is how you chose to maintain) or heavy lifting equipment. As most catch basins can be accessed from ground level, there is no requirement for confined space entry, reducing maintenance costs.

1. Lift

Lift basket out of pit using handles

2. Tip

Tip the contents out of basket into suitable receptacle for contents

3. Reuse

Place the basket securely back into surrounding frame, ensuring a good seal

LittaTrap filters should be inspected periodically to determine maintenance frequency. The frequency of maintenance services should be reviewed at the completion of each clean and modified if pollutant loadings deem this necessary. At the required maintenance interval the contaminants need to be removed from the filterbags and disposed of appropriately. The maintenance crew is responsible for the disposal of debris in accordance with all applicable regulations and is responsible for following all Health and Safety requirements.
