The LittaTrap is a catch basin insert that sits inside the stormwater drain and  catches plastic & litter caught up in the stormwater runoff before it can reach rivers, lakes and oceans.

The LittaTrap's patented gross pollutant 5mm mesh basket is designed to capture and retain 100% of plastic and other debris over 5mm.

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.

When stormwater runoff enters a catch basin with a LittaTrap installed, the water passes through the patented LittaTrap bag and ALL the plastic and pollutants larger than the holes in the filter bag
( 5mm) are captured and retained. When the bag is full, it can be simply lifted out and tipped into either recycling or landfill.

Technical Documentation

Measuring a catch basin to install a LittaTrap

As most catch basins are situated on the road or in busy traffic areas , traffic control must be well planned when measuring a catch basin. 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 need to be identified & control methods put in place prior to undertaking any activity.

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.

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

2. Tip

3. Replace

Replace LittaTrap securely back into surrounding frame and 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.
