Dewatering Bag Specifications

Dewatering silt bags, also referred to as filter dewatering bags or sediment filter bags, are widely known as effective BMPs (Best Management Practices) for removing sediment, sludge, or oil and sediment from construction sites, processing ponds, and other areas where water needs filtration. These durable, non-woven geotextile fabric bags are designed to surround and trap unwanted materials while allowing clean water to pass through. Simply place the bag on an aggregate or haybale bed for optimal performance.
