PIG® Stormwater Filter Sock

Remove hydrocarbons, chemicals, trash and debris from stormwater runoff and boost your erosion control efforts with our innovative dual-chamber Filter Sock.

• Filter sock allows water to pass through as it removes oils, sediment, trash, debris and other pollutants from your stormwater runoff
• Patent-pending, dual-chamber design: highly absorbent proprietary filler pulls in oil and filters water; a separate chamber is filled with stone ballast to keep sock in place
• Weighted sock eliminates the labor and expense of staking or trenching
• Durable geotextile skin removes total suspended solids (TSS) over 297 microns (50 mesh) and maintains an impressive flow rate of 2 gpm per foot
• Flexible design follows the contours of uneven ground for maximum surface contact; can be shaped, even at right angles, to create fully contained spaces
• Heavy-duty straps make filter socks easy to carry while you install, reposition or replace socks
• Highly efficient erosion control solution; reduces pollutant release and water flow rates while eliminating environmental nutrient discharge
• Protect more than your drains! Also ideal for source pollutant removal around grease dumpsters, garbage dumpsters, oil containment areas, roof drains, property perimeters, outfall pipes, downspouts, culvert pipes, stock piles, washdowns, outdoor cooling systems and other oily applications
• Use standalone for smaller applications or use multiple units in a treatment train for source-to-drain protection
