Catch Basin Inserts / Basket Filters
Catch basin Inserts / STORMWATER Basket Filters
Effectively Capture Pollution at the Grate: Introducing SOP Technologies Drop Inlet Screens / Basket Filters.
Engineered with our patented technology, our Stormwater Catch Basin Inserts offer advanced debris capture for grate openings. This solution not only significantly reduces pollutants entering our rivers, lakes, and oceans but also simplifies maintenance and helps prevent costly street flooding, making your stormwater management more effective.
Easy Drop-In Installation
Our patented stormwater basket filters simply drop into place between the grate and the grate frame for quick and easy installation.
Custom-Fit for Maximum Capture
We customize filters based on existing infrastructure dimensions, ensuring a perfect fit and maximizing capture volume for your specific grate openings.
Adaptable & Proven Design
Engineered to fit various grate types, our anti-clogging, upward-flow design is proven in the field and lab to maximize water flow while capturing pollutants.
Flexible Cleaning Methods
Captured debris can be removed by hand by lifting the basket from the grate, or easily vacuumed out with a vacuum truck.
Effective Pollution Control
These filters capture a wide range of debris, including organic material, plastic trash, and cigarette butts, preventing it from entering waterways.
O&M Software Included FOr Free
Included with our stormwater system are our patented QR Code Storm Drain Markers and software for Operations and Maintenance (O&M) teams and Community Engagement. Use the QR Code Markers and software for Asset Management, engaging your community to share what they see, and to log activities for MS4 and NPDES reporting.






See our patented Basket Filter/Catch Basin Insert Filter in action! Our custom-fit design offers superior protection for waterways and infrastructure right at the grate. This allows maintenance and operations teams to decrease the cost of cleaning catch basins and stormwater pipes.
Explore Our Innovations
-
Our Basket Filters / Drop Inlet Screens are designed with an integrated overflow bypass capability to prevent backups during extreme rain events.
In situations of exceptionally high water flow, the overflow bypass allows excess water to flow unimpeded.
The bypass prevents street flooding and can be built based on your preferences (e.g. larger bypass opening for areas with more expected rainfall).

For installations requiring the highest level of precision and fit, SOP Technologies offers the ability to perform 3D scanning of existing infrastructure.
This advanced capability allows us to obtain highly accurate measurements, enabling us to customize each filter to maximize capture volume and ensure a truly seamless integration within unique grate and catch basin geometries.
While basic dimensions are usually sufficient, 3D scanning provides unparalleled accuracy for challenging or complex environments.
