The LittaTrap™ typically requires maintenance two to four times a year across Canada. The most commonly used unit in Canada is designed with 45 liters 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 the unit is lifted by two workers who are trained in standard lifting technique with equipment as necessary to avoid putting unnecessary weight on 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 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.
