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.

Manhole inlet filter

Manhole Inlet

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

Enviropod™ LittaTrap Performance Liners

The performance of the LittaTrap can be enhanced by the use of Enviropod micron performance liners to target site-specific pollutants. The liners are easily attached to the LittaTrap basket and allow the capture of finer particles such as plastic pellets.
