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
Lowest cost treatment available – No construction means low capital costs
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 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.)
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.
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
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.View our range
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.
Ensure to follow the instructions when installing a LittaTrap.
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.
Lift basket out of pit using handles
Tip the contents out of basket into suitable receptacle for contents
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.
Between June-December 2019, the LittaTrap unit caught a total of 473 gross pollutants. Almost 60 percent of all pollutants were cigarettes.
'....Chemicals released from cigarettes release enough toxins to kill over fifty percent of the fish exposed to those toxins within 96 hours....'
Enviropod Canada in conjunction with their partners Imbrium Systems approached the Brampton Public Works team to trial the Enviropod technologies: the Enviropod Filterand the LittaTrap.
In 2016 students from Wilford School took part in the Experiencing Marine Reserves programme and identified litter washing up on local beaches as the problem they wanted to tackle. Stormwater360 donated two LittaTraps to the school to assist the children in their monitoring.
Six kg's of plastic pellets stopped from entering the waterways from one LittaTrap in a 12 month monitoring period.
A trial LittaTrap was installed in a busy loading zone storm drain to monitor how much plastic and litter would be caught and retained.
A single catch basin insert was installed on the corner of Beresford Street and Hopetoun Street, Auckland. The aim of the trial is to provide quantitative and qualitative data on the gross pollutants captured by the LittaTrap in a typical inner city Auckland catchment.
EXPOL are committed to protecting the natural environment and were concerned that waste material from manufacturing their polystyrene products was entering waterways via the stormdrains. A LittaTrap™ was installed to provide data on the effectiveness of capturing the very fine polystyrene particles and other gross pollutants.
Lab testing by the Brisbane City Council, Australia concluded that the Enviropod LittaTrap basket was capable of collecting and retaining large amounts of gross pollutants at high flow rates.
This report details the results of approximately 6 months monitoring of 155 Enviropod LittaTraps installed in selected gullypits within the Brisbane CBD, Australia.
