We have developed a measuring method where we ask you to take photos of the catch basin/s so we can determine the correct size of LittaTrap™. We require your assistance by following the step-by-step instructions on our Measure Up video.

Please ensure that you have location services turned on, on your smartphone device. Also, please take note of the Health & Safety recommendations on the video.

The LittaTrap™ is easy to install if you have the right equipment. We have an installation instructional guide that goes through the step-by-step process.  In some area's we have installation contractors we work with that we can provide details for. Contact us at 0800STORMWATER for more details.

The typical LittaTrap™ maintenance interval is 1 – 2 times a year. We recommend doing this at the start and end of Fall (Autumn).  Leaves and gross solids tend to compress in the device over time and are not a problem if the unit is maintained.  The system has a flow bypass that allows water and debris to travel around the system if it has not been maintained and is full. 

The frequency of maintenance services should be reviewed at the completion of each service and modified if pollutant loadings deem this necessary. If the site has a high pollutant loading more maintenance will be required.  Please see our maintenance instructional LittaTrap™ video.

The LittaTrap™ has been designed to overcome the problems of simple and earlier catch basin inserts such as leaf traps. While the LittaTrap™ looks simple it is a highly engineered device that manages the large forces and high flow rates experienced by a stormwater treatment device.  The patented basket is approximately 100 litres in volume (600mm x 600mm LittaTrap™) and has a bypass that is designed for approximately 3 times the flow that the average catch basin would receive in a 1 in 10-year storm. The LittaTrap™ is designed to not cause flooding and be easily maintained when full.
