Professional-grade patented stormwater filtration system designed to capture silt, sediment, and debris before entering storm drain inlets. The flagship Dandy Bag features unique 30" x 30" square dimensions engineered to reliably filter sediment-laden stormwater in construction sites, parking lots, and municipal applications. This durable filtration bag works with flat grates (including round openings) and mountable curbs to slow stormwater flow, allowing suspended solids to settle out and be captured prior to entering the inlet. The bright orange monofilament geotextile remains visible in any weather conditions for easy inspection and compliance verification. Unlike single-use sediment bags, the Dandy Bag can be reused multiple times for cost-effective, ongoing compliance-level performance.
