Bio Clean® Catch Basin Inlet Filters

Bio Clean® Catch Basin Inlet Filters

Bio Clean Catch Basin Inlet Filters provide the first defense against trash and other pollutants entering your stormwater system by providing 100% trash capture at the source.

Catch Basin Inlet Filters

*Catch Basin Inlet Filters are only available in California

Our nation has some of the world’s most beautiful beaches and waterways. Unfortunately, trash such as cigarette butts, food packaging, cans and bottles, and plastic waste makes its way into streams, creeks, rivers, and the ocean, as rain events wash them into gutters and storm drains

Bio Clean Catch Basin Filters provide the first defense against trash and other pollutants entering your stormwater steam by providing 100% trash capture at the source, preventing system clogging and improving downstream water quality.

Trash Removal

Many municipalities have enacted specific trash control strategies in response to TMDLs or municipal stormwater permit requirements. To address these issues, stormwater managers, municipal officials, and other stakeholders need solutions like Contech's Catch Basin Inlet Filters, Debris Separating Baffle Box, and CDS hydrodynamic separators that can remove trash and TSS, which are easy to maintain, and can easily be implemented in a retrofit scenario.
