Eco Passive Filtration Plates for Sustainable Urban Rain Runoff Solutions

Sustainable cities demand low-impact, reliable water management. Eco passive filtration plates—installed in drains, gutters, or landscape swales—block pollution at the source, improve water quality, and eliminate the need for complex powered filtration.

Project Highlight — Oslo Campus Stormwater Retrofit

In 2023, the University of Oslo upgraded its rain runoff system with passive drainage filter plates on all campus roads and green spaces.
Project highlights:

• 92% decrease in visible trash and organic debris in drains

• Fewer maintenance visits (from 9 to 2 per year)

• NS-EN 1433 European Drain Standard

• SGS Water Filtration Testing

Advantages of Eco Passive Filtration Plates

Non-Electric, Always-On Filtration

Plates rely on mesh design and gravity—no moving parts, wiring, or power source required.

Maximum Durability, Minimum Service

Stainless or composite materials, tested for over 10 years’ life in salt, ice, and pollution.

Easy Fit for New or Retrofit

Plates can be dropped into existing curb inlets, manholes, green swales, or new construction.
