Delivering Certified Full Trash Capture for Municipal Stormwater Networks

‍

Located in San Bernardino County, California, the City of Colton—known as the "Hub City"—is committed to protecting local waterways.

To support compliance with California's stringent stormwater regulations, the City of Colton Public Works Department approved the installation of 10 EnviroPod™ LittaTrap™ FC Curb Inlet units across municipal catch basins along public streets.

The project was installed by Storm Water Inspection & Maintenance Services (SWIMS), providing the city with a certified Full Trash Capture solution that was quick to install, easy to maintain, and designed to perform in real-world municipal environments.

‍

The Challenge

The City required a stormwater treatment solution capable of:

  • Meeting California State Water Board Full Trash Capture (FTC) requirements
  • Retrofitting into existing municipal catch basins
  • Minimising installation time and disruption to public roads
  • Capturing large volumes of litter and debris while maintaining hydraulic performance
  • Providing a long-term, low-maintenance solution for ongoing compliance

Many of the existing catch basins varied in condition, meaning installation flexibility was critical to the project's success.

‍

The Solution:

The LittaTrap™ FC Curb Inlet was selected for its certified Full Trash Capture performance, modular design, and ability to retrofit into existing infrastructure without major civil works.

Installed beneath the curb inlet grate, the LittaTrap™ captures trash and debris before it enters the stormwater network, helping prevent pollution from reaching downstream waterways.

The project included:

  • 10 municipal installation locations
  • Seven-foot curb inlets fitted with dual LittaTrap™ FC units
  • Modular retrofit installation
  • High-capacity debris capture
  • Built-in bypass functionality during extreme flow events

The flexible design enabled fast installation regardless of individual catch basin conditions. In many cases, cleaning accumulated sediment from the existing vault required more time than installing the LittaTrap™ units themselves.

Design Features:

The LittaTrap™ system was selected for several key performance advantages:

  • California State Water Board Certified Full Trash Capture device
  • Modular retrofit design suitable for existing infrastructure
  • Dual-basket configuration for oversized curb inlets
  • High-flow hydraulic performance
  • Three cubic feet of debris storage per basket
  • Integrated bypass function to maintain flow if maintenance is delayed
  • Simple hand maintenance without confined space entry

The modular construction also allows the system to accommodate variations commonly found in existing municipal drainage assets.

‍

Key Benefits:

  • Achieves Full Trash Capture compliance
  • Protects downstream waterways from litter and gross pollutants
  • Fast installation with minimal disruption to traffic
  • Flexible retrofit solution requiring no major infrastructure modifications
  • Reduced maintenance complexity
  • High debris storage capacity
  • Reliable hydraulic performance during storm events

‍

Maintenance:

LittaTrap™ has been engineered for simple, efficient maintenance.

Routine servicing can be completed quickly by removing accumulated debris from the baskets without confined space entry. The integrated bypass function ensures continued stormwater conveyance during larger storm events should maintenance be delayed.

Maintenance frequency can be tailored to site conditions and pollutant loading, helping municipalities optimise operational costs while maintaining compliance.

‍

Conclusion:

The City of Colton project demonstrates how municipalities can achieve California Full Trash Capture compliance using a practical retrofit solution that is both cost-effective and easy to maintain.

By installing 10 LittaTrap™ FC, the city strengthened its stormwater management programme while protecting local waterways from litter and debris before pollutants entered the drainage network.

With certified performance, rapid installation, and straightforward maintenance, LittaTrap™ continues to provide municipalities across California with a proven at-source solution for meeting stormwater compliance requirements and improving water quality.
