Rain Guardian

Curbline Pretreatment Structure

The Rain Guardian is an effective stormwater pretreatment structure. It works well in bioretention, rain gardens, vegetated BMPS, and other related systems. Furthermore, it is a premium solution for both retrofits and new construction. These pretreatment devices are often used in urban curb-line applications that lack the space for standard sediment forebays. Multiple configurations are available and meet both commercial and residential needs. All configurations include a grate, filter, and chamber combination with overflow points to prevent inlet debris from causing bypass before the system reaches capacity.

Unlike other pretreatment systems, Rain Guardians are very maintenance-friendly, and can be inspected visually. Remove sediment easily from the chamber using a shovel and clean the drop-in filter with a broom or hose.

Key Features:

• Maximizes capacity and extends the life of bioretention systems
• Maintenance is simple – it only requires a shovel and a broom or hose
• Installation is quick – placement and securing take only minutes
• The system helps eliminate bypass and sediment build-up, protecting surrounding vegetation
• Works well with new construction, retrofits, and tight urban spaces
• Visual inspections of accumulated sediment depth are easy
• Multiple configurations available for both commercial and residential needs

Why is Pretreatment important?

Pretreatment is a critical component in a variety of stormwater systems, like FocalPoint. Without a pretreatment system, high quantities of sediment, trash, and debris are likely to clog the system resulting in costly repairs.
