Engineered for Modern Stormwater Networks 

Developed and engineered by the Storwater360 Group, the LittaTrap™ evolved from New Zealand’s first patented catch pit insert system and has since become one of the most widely adopted inlet filtration technologies globally.

The LittaTrap™ is a modular, adaptable inlet filtration device designed to capture gross pollutants, litter, sediment, hydrocarbons, and other stormwater contaminants at the source — supporting water quality objectives, regulatory compliance, and improved asset performance.

Designed for retrofit and new-build applications, the system can be configured to suit a wide range of catch pit and inlet environments across municipal, industrial, commercial, and transport infrastructure projects.

With more than 75,000 installations across New Zealand, Australia, Canada, the USA and beyond, LittaTrap™ is trusted by engineers, councils, contractors, and asset owners for its:

• High hydraulic efficiency
• Modular retrofit adaptability
• Lightweight maintenance access
• Proven field performance
• Long-term operational durability
