The Enviropod™ 200 is our patented structural mesh basket coupled with a 200 micron liner designed to capture sediments, litter, debris, total suspended solids (TSS), nutrients, metals, and hydrocarbons conveyed in stormwater runoff.
The Enviropod200 is available in several standard sizes, designed to fit pits ranging from 450 x 450mm up to 1200 x 1200mm. Custom designs are also available for larger pits and the unit can be installed in kerb entry, grated drain and field catch basins.
The Enviropod200 removes gross pollutants, sediment and associated pollutants making the the device a Stormwater Quality Improvement Device ( SQID) . Ideally used as a pre-treatment device for use in a treatment train with hydrodynamic separators, filtration devices, ponds and wetlands. In many cases, it is often the most practical solution for retrofits as it requires no alterations to the drainage network. Independently trialled and tested by city councils throughout Australia and New Zealand, the Enviropod200 is the most specified and installed pit insert in Australasia.
The Enviropod 200 is installed with a 200 micron liner for complete capture of gross pollutants ≥ 200 micron
Placed inside the stormwater drain gully pit, the EnviroPod 200 captures and retains any sediment and gross pollutants caught up in the stormwater runoff.Stormwater flow enters the gully pit through a grate, kerb entry or both, and enters the patented basket before passing over oil adsorbent pads (optional) and through the filter liner.The filter liner captures pollutants and allows the water to pass through to the outlet pipe. The optional absorbent material inside the screening bag captures oil and grease caught up in the stormwater runoff. Once the filterbag is full, it can be lifted out and emptied by hand or contents can be removed by a vacuum inductor truck. If the filterbag is full or during high flows, overflow is released through the overflow apertures in the frame assembly.
The EnviroPod 200 consists of a Support System, Plastic Seals, Flow Diverter, Energy Dissipator, Basket, and Adjustable overflow Bypass. Components comprise of inert engineered plastics.Support system brackets fix the unit to the gully pit wall below the stormwater drain grate allowing the filter bag to be easily lifted out for hand maintenance. Modular plastic deflector seals attach to the filterbox and guide the flow of water to the filter bag. Openings in the filter box allow water to bypass the filter bag during high flow conditions to prevent surface flooding.Once the filter bag has been removed for maintenance, open access to the base of the gully pit and outlet pipe means any accumulated sediment in the pit can easily be removed by inductor truck if required.
The EnviroPod 200 is available in several standard sizes, designed to fit pits ranging from 450 x 450mm up to 1200 x 1200mm. Custom designs are also available for larger pits. The EnviroPod 200 can be installed in kerb entry, grated drain, and field gully pits.
All treatment devices require maintenance to remove trapped contaminants and to minimise bypass. Due to the variable nature of stormwater pollution and localised site pollutant loadings, maintenance frequencies vary for different sites and different rainfall characteristics.To ensure that each EnviroPod 200 achieves optimal performance, the unit should be maintained every 6-12 months; however it is dependent on the catchments’ pollutant loading.Maintenance is a simple process that requires no confined space entry. Maintenance can be quickly undertaken using a vacuum truck or it can be maintained manually by hand.
Between June-December 2019, the LittaTrap unit caught a total of 473 gross pollutants. Almost 60 percent of all pollutants were cigarettes.
