Circular Drain Inlet Protection Filter

Capture Sediment Before It Reaches Storm Drains

Sandbaggy's Circular Drain Inlet Protection is a patented, above-ground filtration system designed to reduce sediment and debris from entering grated storm drain inlets in paved areas. The integrated filter captures sediment while allowing stormwater to flow, helping support erosion and sediment control efforts on construction sites.

The system features an outer berm that allows water to rise up to approximately 1.5 inches before reaching the filter, encouraging heavier particles to settle above ground for easier inspection and maintenance. Its durable, reusable design withstands construction traffic, installs without removing the drain grate, and provides reliable performance throughout the project.

Features

• Captures Sediment Above Ground – Helps prevent sediment and debris from entering storm drains while making inspection and cleanup easier.
• No Grate Removal Required – Installs and maintains without lifting heavy drain grates, improving safety and reducing labor.
• Built-In Settling Berm – Outer berm allows water to pond before filtration, helping heavier particles settle out before reaching the filter.
• Handles High Flow Conditions – Integrated high-flow bypass helps maintain drainage performance during storm events.
• Durable & Reusable Design – Built to withstand construction traffic and remain in service throughout the project.
• Reduces Maintenance Costs – Above-ground filtration allows faster inspection, cleaning, and removal compared to traditional inlet protection methods.

FAQs

What type of drains is this designed for?

Sandbaggy's Circular Drain Inlet Protection is designed for grated circular storm drain inlets located in paved areas.

Does the drain grate need to be removed during installation?

No. The system installs above ground and does not require grate removal.

How does the outer berm improve performance?

The berm allows water to rise before reaching the filter, helping heavier sediment particles settle out above ground.

Can it handle heavy rain events?

Yes. The integrated filter is designed for high-flow conditions and includes a bypass feature to maintain drainage.
