FAQ Catch Basin Installation & Maintenance
Yes, a standard-sized LittaTrap™ unit has been designed to ensure hand maintenance at full capacity. Enviropod advises the unit is lifted by two workers who are trained in standard lifting techniques. However, some LittaTrap Curb Inlet configurations may require vactor trucks to maintain.
As of 2015 in California, the State of California adopted statewide provisions that are applicable to all regulated stormwater discharges to surface waters. The State of California has set the goal of zero percent discharge by 2030 and requires the capture of all particles five millimeters of larger from peak flow generated for a one year, one hour storm event. A certified full capture system such as the LittaTrap™ FC must be used to meet these objectives.
EnviroPod™ can provide nationwide installation services through recommended installation partners. Please reach out to Enviropod™ today for an installer in your area.
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 smaller pollutants such as plastic pellets, PVC cuttings and microplastics
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.
Yes, the LittaTrap™ FC has been certified as a Full Capture System of Trash Treatment Control by the Californian State Water Resources Control Board. This means the LittaTrap™ FC can be implemented statewide to meet your trash capture regulation objectives.
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.
Yes, 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. Please note, as of 2021 all full capture systems used within California must be verified by MVCAC.
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.
The LittaTrap™ typically requires maintenance two to four times a year across America. 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.
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.
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.
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.
