The EnviroPod™ LittaTrap™ is a modular and versatile inlet filter device that is designed to capture trash, debris, sediments and other pollutants of concern conveyed in stormwater runoff.
The LittaTrap™'s mesh basket is designed to capture and retain 100% of plastic and other gross pollutants 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™ has been manufactured in multiple standard sizes to fit a range of grated inlet, curb inlet and manhole catch basin structures, and custom designs are available. The LittaTrap™ can also be designed for different pollutant removal requirements using site-specific performance liners. li
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
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. The basket is lightweight and is 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 stormwater drain 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
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.
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.
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 catch basin 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.
A pilot project in a plastic manufacturing facility looked at the effectiveness of the LittaTrap™ in capturing pre-production plastic pellets.
By installing 30 x LittaTrap™'s a total of 248.84kg of litter and debris was prevented from entering the Atlantic Ocean from the City of St Johns.
