LittaTrapCatch Basin Insert

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 available across the USA, Canada, Australia and New Zealand and with over 50,000 installed it is the world's leading stormwater Catch Basin Filter.


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.
- Varying configurations

Stop trash, debris , sediment and plastic in stormwater runoff

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™  is lightweight and is designed to
be lifted by hand with no confined space entry required

Independently tested

Independently trialled and tested by city councils throughout Canada, 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.

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 stormwater drain wall; halving installation time.

Grate Inlet 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.

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

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.

The LittaTrap™ is designed to be simply inserted into the catch basin and has a number of different configurations.

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 catch basin using handles.

Tip LittaTrap

2. Tip

Tip the contents out of basket into suitable receptacle for contents.

Replace LittaTrap

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.
