Foster City Commercial Development Protects Waterways with LittaTrap™ Full Capture Technology

As new commercial developments seek to improve environmental performance and sustainability, stormwater management plays an increasingly important role. Preventing pollutants from entering waterways at the source not only protects the environment but also supports green building initiatives and long-term asset performance.

To achieve these outcomes, EnviroPod™ International, together with installation partner Storm Water Inspection and Maintenance Services (SWIMS), installed 10 LittaTrap™ FC (Full Capture) Grate Inlet Filters at a new commercial development in Foster City, California.

The Challenge:

The Foster City site is a modern commercial/light industrial development where stormwater runoff from the parking areas drains into ten catch basins before discharging directly to the adjacent lagoon and local waterways.

Although the development was not subject to mandatory stormwater discharge monitoring or local permit requirements, the project team wanted to implement a proactive stormwater treatment solution that would:

  • Prevent litter and plastic pollution entering local waterways
  • Capture fine pollutants associated with commercial runoff
  • Meet sustainability objectives
  • Be easy to install within existing infrastructure
  • Minimise future maintenance requirements

The project also aimed to contribute towards the site's LEED Silver accreditation through improved environmental performance.

The Solution:

Ten 18" × 18" LittaTrap™ FC (Full Capture) Grate Inlet Filters were retrofitted into the site's existing catch basins.

Each unit was fitted with:

  • 400-micron performance liners
  • Filtration media pouches designed to target:
    • Hydrocarbons
    • Copper (Cu)
    • Zinc (Zn)
    • Aluminium (Al)

The LittaTrap™ FC combines California-certified Full Trash Capture performance with enhanced pollutant removal, enabling the system to capture:

  • 100% of litter and debris larger than 5 mm
  • Fine suspended pollutants
  • Hydrocarbons
  • Heavy metals associated with urban runoff

Installation:

One of the major advantages of the LittaTrap™ system is its simplicity.

The project was completed with:

  • Average installation time of just 15 minutes per catch basin
  • No excavation
  • No modifications to existing infrastructure
  • Minimal disruption to site operations

The modular design enabled rapid deployment while maintaining full hydraulic performance.

Greg Yeoman, President of EnviroPod™ International, commented:

"The LittaTrap™ units were installed in an average of 15 minutes per catch basin and required no on-site modifications. The product satisfied all the technical and performance requirements for site compliance and had the added benefits of easy hand maintenance post install. The LittaTrap™ checked all the boxes for the customer."

Andy Hughes, Project Manager at SWIMS, added:

"SWIMS has a lot of experience installing trash control devices in California, and we like the flexibility of the LittaTrap™ design and ease of installation."

Project Outcomes:

The installation delivered multiple environmental and operational benefits, including:

  • Full Trash Capture performance
  • Enhanced removal of hydrocarbons and heavy metals
  • Protection of adjacent lagoons and waterways
  • Rapid retrofit installation
  • Simple hand maintenance
  • No changes required to existing drainage infrastructure
  • Contribution towards the development's LEED Silver certification

Why LittaTrap™ FC:

For commercial developments, the LittaTrap™ FC provides an effective retrofit solution that combines regulatory compliance with enhanced water quality treatment.

Key Benefits

  • California State Water Board Certified Full Capture Device
  • Captures 100% of trash and debris greater than 5 mm
  • Retrofit installation into existing catch basins
  • Customisable liners for enhanced pollutant removal
  • Simple hand maintenance
  • Supports sustainable development and green building objectives
  • Protects receiving waterways at the source

Supporting Sustainable Development:

As commercial developments continue to prioritise sustainability, stormwater treatment solutions that are practical, high-performing, and easy to maintain are becoming essential.

The Foster City installation demonstrates how LittaTrap™ FC can be integrated into new developments to deliver immediate environmental benefits while supporting long-term asset management and green building certification.

Today, the LittaTrap™ Grate and Curb Inlet Filter FC product range is certified by the California State Water Resources Control Board as a Full Trash Capture Device, helping municipalities, developers, and commercial property owners meet California's stringent trash capture requirements while protecting local waterways.
