The junction EnviroBasin™ allows for inlet pipes without impacting EnviroBasin™ performance.
This is where the EnviroBasin™ excels! The EnviroBasin™ takes the place of standard catch basins and is a fraction of the cost of a standard OGS saving money on installation and concrete while still achieving the required removal standards.
The EnviroBasin™ is ETV Verified and has a performance efficiency calculator which can be used to estimate removals for specific catchments. Fill out and email our project form to barryi@enviropod.com along with site plans and our technical team can verify the EnviroBasin™ will meet the removal required for your site.
The EnviroBasin™ is the best device on the market for pretreatment, whether it is filters, infiltration, or biofiltration. The Gross pollutant basket removes large pieces of litter and debris such as plastics or other neutrally buoyant objects that typically bypass standard OGS systems. Having multiple devices with sumps in a catchment also allows for greater sediment storage in some situations, meaning the downstream devices are focused on treating fine pollutants which extends their required maintenance frequency and helps improve their function overall.
The EnviroBasin™ is also great for large sites with many catch basins. The project with Aecom installed 35 EnviroBasins™ instead of traditional OGS in front of green infrastructure.

The LittaTrap™ is a catch basin filter insert designed to capture trash, debris, and plastic pollution before it enters the stormwater system. Flexible and easy to install, it is widely used by municipalities, commercial sites, and industrial facilities to protect waterways and improve stormwater quality. The LittaTrap™ can also include the EnviroPod™ Performance Liner to target specific pollutants.
The LittaTrap™ is installed inside a stormwater catch basin on engineered brackets and uses a patented design to capture and store gross solids from stormwater runoff.
How it functions:
1. Stormwater enters the catch basin through a grate or curb inlet and flows into the LittaTrap™ filter insert system.
2. The LittaTrap™ basket captures trash, debris, and other pollutants while allowing water to pass through to the outlet pipe.
3. During high flows or when the basket is full, excess water is safely released through overflow bypass apertures in the frame.
Maintenance: Easy and straightforward, it can be performed by a single person by hand lifting the insert out and emptying it into the trash or by a vactor truck.
The LittaTrap™ FC is California Water Board Full Trash Capture Certified by the CA State Water Board and is now available in California to meet stormwater regulations. The LittaTrap™ FC has been verified by MVCAC to ensure that inspection and treatment for the purpose of minimizing mosquito production is possible by MVCAC operation.
It is also an official supporter of Operation Clean Sweep in the USA & New Zealand. It is endorsed by the plastic industry associations in New Zealand, Canada, and Australia. It’s a key technology for Operation Clean Sweep compliance and preventing plastic pellet loss with the inclusion of the nurdle performance liner, reaching zero pellet loss.
The LittaTrap™ is trusted by public works, cities, developers, private owners and major industries, including the petrochemical, logistics, and manufacturing sectors, to capture pollutants and reduce stormwater contamination at the source. It helps organizations meet environmental regulations and achieve stormwater compliance while protecting local waterways.
The EnviroBasin™ is an all-in-one precast Water Quality Inlet (WQI) is a hydrodynamic separator and catch basin all-in-one within a standard catch basin footprint. Installed to capture and treat stormwater runoff at the source, removing sediment, trash and debris before it reaches local water bodies.
Designed for urban and space-constrained environments, it delivers high-performance stormwater treatment right at the source, removing pollutants before they enter the drainage system.
The EnviroBasin™ is available in a variety of sizes and configurations and is ideal for a pre-treatment solution for LID, rain gardens, tree cells and urban green infrastructure.
The EnviroBasin™ is also an ETV-certified device and has the equivalent performance of an Oil and Grit Separator (OGS).
The EnviroBasin™ captures and retains sediment, gross pollutants, and heavy metals before stormwater reaches downstream systems. It efficiently conveys peak stormwater flows without resuspension. The EnviroBasin provides effective pre-treatment at the source, enhancing the performance and longevity of Low Impact Development (LID) infrastructure such as tree cells, rain gardens, and bioretention basins.
The EnviroBasin™ is used across Canada in Ontario and British Columbia, including cities such as Toronto, Town of Innisfil, Kelowna, South London, Etobicoke, and London.
The EnviroBasin™ is an ETV-certified device and has the equivalent performance of an Oil and Grit Separator (OGS). Trialled and verified in Canada to the Canadian ISO 14034 ETV verified Oil and Grit Separator standard. The EnviroBasin™ is independently trialled and tested by Good Harbour Labs in Canada for the Canadian climate.
The LittaTrap™ typically requires maintenance two to four times a year across Canada. The most commonly used unit in Canada is designed with 45 litres of storage capacity, keeping maintenance cycles low.
Please note, this number can vary, and EnviroPod™ recommends regular checks of LittaTrap™ units for the first year post-installation to establish a site-specific maintenance plan.
As leaves enter the LittaTrap™ unit, subsequent water pressure compresses incoming leaves and ensures they will lot clog, blind or quickly fill the LittaTrap™ unit. Enviropod does advise maintenance both before and after the fall period to minimize the effect of leaves on overall storage capacity.
The LittaTrap™ is designed from engineered structural plastics that are both UV stable and freeze resistant. Said plastics will not corrode or leech pollutants and have been extensively tested to withstand winters across multiple North American locations. Frozen water may build up in the LittaTrap but will not back up and can escape via the overflow bypass slot once it thaws.
A standardly sized LittaTrap™ unit has been designed to ensure viable hand-maintenance at full capacity. EnviroPod™ advises that the unit is lifted by two workers who are trained in standard lifting techniques with equipment as necessary to avoid putting unnecessary weight on the lifters' backs.
The support bracket (comprised of fibreglass reinforced plastic) has been designed assuming a load of 440 pounds in the basket at 300 liters per second pass through. In addition, structural testing completed by Enviropod has shown negligible deflection on the bracket at 580 pounds and 140 pounds on the basket. This will ensure the LittaTrapTM™ is not compromised even assuming full capacity during a once in a decade storm.
An overflow bypass of 4 ½ inches has been added to the LittaTrap unit to promote optimal flow rates even when at maximum design capacity. To ensure maximum flow rates, please make sure you are maintaining the LittaTrap™ prior to 80% capacity of the basket.
In order to ensure the LittaTrap™ can withstand significant weight and ranging weather conditions, specific engineer structural plastics have been used that cannot be readily sourced from recyclable plastics. To minimize waste, Enviropod uses minimal packaging and online installation guides.
The LittaTrap™ was introduced to Canada in response to the growing marine plastic problem identified via the Ocean Plastics Charter. A body of water that provides 21% of the worlds water supply, the Great Lakes are currently subjected to an estimated 22 million pounds of plastic debris annually with significant sediment pollution also occurring. This pollution can be minimalized through LittaTrap™ installation.
EnviroPod™ can provide nationwide installation services through the recommended installation provider, Minotaur Stormwater Services.
A standard LittaTrap™ unit is supplied with a five-millimeter, enabling the capture of over 99% of gross pollutants whilst keeping maintenance cycles relatively low. Capture can be enhanced through a performance enhancing liner which will enable the capture of additional pollutants such as plastic pellets, PVC cuttings and microplastics.
The performance of the LittaTrap™ can be enhanced by adding the plastic pellet liner which enables the capture of all pollutants greater in size than one millimeter. Plastic pellets are sized two to five millimeters, so full capture of pellets is achievable. Given the density of plastic pellets, they are prone to floating in water. As a result, Enviropod recommends utilizing the bypass removal feature for application when attempting to capture plastic pellets. Units in this application will require additional maintenance to ensure units do not cause flooding.
Yes, LittaTrap™ installation facilitates reduced resuspension through energy dissipation. This enables significantly higher capture of sediment at the sump of the catch basin, with third party testing showing 50% TSS removal at four liters per second.
The LittaTrap™ basket has been designed with a structural baton running across all four sides of this design. This will prevent the bag from bulging, even at full capacity. As a result, the weight will be evenly distributed which will make maintenance easier and help promote optimal water flow.
The LittaTrap™ has been designed with ease of installation in mind. Few parts have kept installation as simple as possible, and the device can be installed by all installation providers. To ensure confidence, see Enviropod™ installation video available at our website.
Enviropod has a variety of sizes and configurations that have enabled install across ranging catch basin structures. The LittaTrap™ can be installed inside grate inlet, curb inlet and manhole units with custom seal kits available for unique catch basin structures.
Yes, Enviropod use a manhole adaptor kit to offer customers a solution for circular structures across ranging diameters. For more information, please contact Enviropod.
Yes, Enviropod can provide custom solutions based on the size of the curb-inlet unit. For more information, please contact Enviropod.
Yes, LittaTrap™ maintenance is encouraged via use of a vactor truck where hand maintenance is not possible. Usage of a rubber boot and the base of the vactor hose is optimal to avoid a potential tear of the LittaTrap™ bag.
The LittaTrap™ will capture over 99% of all gross pollutants and 50% percent of all total suspended solids (TSS) running into a stormwater drain, equating to approximately 75 percent of the total loading. This will decrease the risk of pipe blockages, reduce the need for a maintenance contractor, protect technology further downstream (i.e. – Jellyfish or Oil Grit Separator) and help you to meet environmental targets.
It is recommended that all LittaTrap™ units are maintained prior to reaching 80 percent capacity as this will enable optimal water conductivity at all times. In the event that your LittaTrap™ reaches full capacity, water will still bypass, and the unit’s structure will support the weight of the basket and incoming water flows indefinitely.
The LittaTrap™ is not degraded, clogged or otherwise affected by annual salting and/or snowing of roads during the winter months. The LittaTrap™ unit is made from engineered structural plastics that will not corrode or leach pollutants in the event of salting or sanding. Similarly to TSS capture, the LittaTrap™ will capture significant quantities of sand and salt that enter catch basins, and stop these harmful pollutants entering waterways.
