The LittaTrap is a low-cost, innovative technology that prevents plastic and trash from reaching our waterways. Designed to be easily retrofitted into new and existing stormwater drains, the LittaTrap is installed inside storm drains and when it rains, catches plastic and trash before it can reach our streams, rivers and oceans.


  • Urban runoff or snowmelt treatment anywhere there is grated inlets
  • Pretreatment of land based systems and LID
  • Pretreatment of manufactured filter systems for reduced maintenance

The LittaTrap is an innovative catch basin insert designed to be easily retrofitted into new and existing stormwater infrastructure to specifically target plastic, trash, and debris, capturing them at source and preventing them from entering our waterways. The LittaTrap is a low cost, easily hand maintained solution for 100% capture of particles larger than 5mm.

The LittaTrap is also effective as a pre-treatment device for use in a treatment train with hydrodynamic separators, filtration devices, ponds, and wetlands. In many cases, it is often the most practical solution for retrofits.


How does it work?

Placed inside the stormwater catch basin, the LittaTrap captures and retains plastic and trash larger than 5mm that are caught up in the stormwater runoff. Once the filter bag is full, it can be simply lifted out and emptied. If the screening bag is full or there are high flows, overflow is released through the overflow apertures in the frame assembly.

The LittaTrap is a low-cost solution to prevent plastic pollution in our waterways and can be easily installed into new or existing drainage infrastructure.

Installing a LittaTrap in a catch basin, captures & retains plastic & trash that would normally be washed down the stormwater drain and out into waterways.


Stop plastic leaving your site

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


Low cost solution

Lowest cost solution of any stormwater treatment device


Simple & easy maintenance

Designed to emptied by hand. The filter bag can be easily lifted and the contents recycled or sent to a landfill.


Innovative design

Can be modified to fit most catch basins


Easy Installation

Simple step-by-step install


Target site-specific pollutants

Using passive screening and optional oil-adsorbent media, the LittaTrap can be customized to meet site-specific requirements

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.

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 or heavy lifting equipment. As the basins can be accessed from ground level, there is also no requirement for confined space entry, reducing maintenance costs.

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.
