Rain Guardian

Rain Guardian

Extending Maintenance Cycles. Simplifying the Maintenance Process.

The Rain Guardian is a highly effective stormwater pretreatment device designed for use in bioretention systems, rain gardens, vegetated BMPs, and similar applications. Ideal for both new construction and retrofit projects, it excels in space-limited urban curb-line settings where traditional sediment forebays aren’t feasible.

Each Rain Guardian unit includes a grate, filter, and chamber with built-in overflow points, ensuring debris is captured without causing bypass before the system reaches capacity. Available in multiple configurations, it serves both commercial and residential needs.

Unlike many pretreatment systems, the Rain Guardian is exceptionally maintenance-friendly. Visual inspections are simple, and maintenance requires only basic tools, a shovel to remove sediment and a broom or hose to clean the drop-in filter.
